Bandage Fe Building Drain Piping: Identification, Diagnosis, Repair

Bandage iron drain piping has been used in buildings for more than 100 years and can concluding for 50 years or longer. T

his heavy cloth is available in diameters from 2" and upwardly, with typical master building drains of four" to six" in bore in residential buildings.

A hub system connects piping sections, originally using melted lead to seal the joint against wastewater leaks or sewer gas odor leaks.

The cast iron pipe hub and stub were wiped with oil to remove water, avoiding a dangerous steam flash when pb was poured into the fitting.

Most modernistic bandage iron connections are made using prophylactic or plastic fittings that no longer require heating and melting lead.

The illustrations (left) testify accessing a bandage fe drain cleanout and two methods of emergency, temporary repair of leaks in drain piping.

Making New Drain Connections to Old Cast Iron Drain Pipage

Our photograph of cast iron drain piping (below left) demonstrates two methods past which connections take been made to newer copper drain lines. At upper left a black plastic hub fitting has been used to connect the four" copper drain to the cast fe drain line.

At center-right in the above left photo a questionable clamp-on type fitting has been used for the aforementioned purpose, including a makeshift clamp using a block of wood to adjust use of the wrong-sized clench effectually the cast atomic number 26 drain. Stains on the upper section of piping signal that this drain system has been leaking.

Our photograph above shows 3 clench-on connectors joining bandage iron and plastic drains to the cast iron sewer line.

Cast Iron Drain Pipe Leak & Odor Locations, Causes, Diagnosis

Our photograph shows an odd double-hub connexion on a vertical section of cast iron drain pipage in a 1935-built abode in poughkeepsie, NY.

You can run across by the rust stains that this bandage iron pipe articulation has been leaking for some time, that the physical "repair" activeness was not fully effective, and that the basement is exposed to unsanitary weather condition due to sewage leakage.

Our second cast iron drain leak photo (beneath) shows a different type of bleed piping leak: sewer gases. This fitting and drove of galvanized iron elbows and nipples should be removed and the opening in the vertical cast iron drain plugged to stop potentially dangerous sewer gases from entering the building.

We suspect that this bleed was once used to receive water from a basement dehumidifier or h2o softener, but information technology is no longer in utilize. The dry "trap" formed at the lesser of the pipe "U" no longer serves to keep sewer gases out of the building.

Watch out: sewer gases may be both unsanitary and also risk of a very serious marsh gas gas explosion.

See SEWER GAS ODORS.

Types of leaks occur in Bandage Atomic number 26 Piping

• Improper cast iron pipage connections or retrofit connections (see our photograph simply below), including poorly-prepared lead hub joints as well as use of improper clamp on or hubless connectors
• Perforations from defective cast atomic number 26 material or corrosive conditions
• Splits in cast iron drains due to freezing - occurring when the drain line is blocked or improperly pitched, left full of wastewater, and exposed to freezing conditions
• Improper support leading to movement and separation of pipe joints.
• Breaks at cast iron pipes or piping joints due to mechanical impact, movement due to poor back up of the cast fe piping, or similar causes.

Our photograph above shows that the rope trying to secure the galvanized drain line to the cast iron sewer pipage confirm a history of leak troubles and improper plumbing connections.

Cast Iron Drain Pipe Leak & Repair Instance - Odors Lead to Discovery of Under-Flooring Drain Leaks

Cast Iron Drains Receiving Roof Gutter Drainage May Burst Basement Floor Slabs

Frequently on metropolis lots that are flat and poorly drained, builders or building owners were pressed to decide how to get rid of rainwater spilling off of building roofs and through the gutter and downspout system.

The best approach is to route these drains to a nearby urban center tempest bleed, pumping if necessary but best by gravity. This avoids overloading the city sewer arrangement during periods of heavy rainfall.

Our photograph above shows a New York Urban center storm drain overflow station (officially, a: New York State Moisture Atmospheric condition Discharge Bespeak) where excess drainage is dumped into the Hudson River when more water or wastewater enters the city sewer system than can be handled. The green sign atop this drain warns

If you see a discharge during dry weather, please call 311 - DEP (Department of Ecology Protection).

Overloading a city'due south sewer often means that raw sewage is simply overflowed or dumped into local rivers or streams.

Merely It was mutual in previous generations for builders to rout (usually cast iron) drain pipes from ground-level outside of a building into the building, under the basement floor slab, and out to the municipal sewer arrangement. These drains were used to receive roof gutter drainage and dispose of it into the city sewers.

Our photo above shows an in-basement cast iron drain line that originally received outside gutter/downspout bleed water. At the time of our inspection that system had been changed and downspouts were routed to to a higher place-ground drains (unfortunately still likewise close to the building to assure a dry basement).

A problem with the in-edifice, under-flooring piping disposal of roof runoff, likewise overloading the city sewers in wet weather, is that somewhen the under-flooring drain may become chock-full, perhaps with leaves washing into the drain from the building'due south gutters. The best result of that problem is that the drain stops draining and gutters spill outdoors along the foundation, possibly leading to basement water entry, rot, mold, and insect harm.

Still more troubling, a blocked under-floor drain in a building left with no heat sometimes led to frozen drain pipes and burst, heaved pipe and floor harm in the edifice, followed past an in-building alluvion when freezing weather changed to a thaw.

If you accept roof gutters continued to drains that enter the building and are routed to the sewers, (a step still permitted and even required in a few communities), reconnecting the drains from outside basis-level to a nearby tempest drain may be a better arroyo.

Reader Comments & Q&A

@Sometime Home,

Sure, could have been a loop vent, though I haven't institute that design common in homes from the 1950s or older.

DRYWELL DESIGN & USES

@inspectapedia.com.moderator, Concur with all. I take found many surprises working in old buildings.

But they do brand me curious why it was done that way and some you lot only shake your head. A thought came to mind.

Could that mystery pipe be the downstream part of a 50s version of a loop vent?

Both have some water in them right at present because of a downstream blockage simply once I cutting them to supplant with PVC I can investigate further.

I'll send my "judge" pic of the loop vent [ shown above ] Let me know if I'm way off base or it could be right. Both pics are in the same area, less than six feet apart

@Onetime Home,

Non really; having worked on many old houses I can prove that information technology's no surprise to find abased plumbing, wiring, and structural components equally a building's features, occupants, uses, needs change over many decades. I've constitute garden hose used equally piping in walls, septic tanks in basements, gutters used in a kitchen to catch roof leaks, dead raccoons in a shower converted to a cupboard.

Every bit long as the building isn't beingness made unsafe or damaged by these left over pipes nosotros cut them off and remove them if possible, else exit them alone during renovations.

But beware; a plumber at a habitation in San Miguel de Allende was making new building main drain connections to the street and didn't see whatever reason why a second bleed, a "mystery piping" needed to exist included, then he just cutting it off and buried it.

Ultimately the occupants found that while almost all of the building's fixtures tuckered to the building's master drain, at present connected to the sewer, a kitchen drain had been routed separately - out through the wall, under the sidewalk, and downwards to bring together the main drain outside. When the kitchen drainage started bubbling upward through the sidewalk the owners knew something was missing.

@inspectapedia.com.moderator, Distressing I didn't proof read that last mail service before striking send. It was a footling jumbled. This is in south Texas. The soil here is very sandy for the first foot of so then more than similar a clay.

Information technology is ordinarily very dry out simply this spot was probably always wet due to all the rusted thru holes in the lesser of nearly of the tee's. As for soil corrosivity, No idea. The h2o is pretty hard. I added a water softener a few years back and considering that pipe carries away the weekly softener regeneration pretty certain that didn't do information technology any favors. Any ideas on what that 2d mystery drain in the pic might be?

@Old Abode,

Looks like all of that needs to be replaced. Where is this dwelling house located ?

and do you know annihilation almost the corrosivity index of your soil?

@inspectapedia.com.moderator, Thank you!

I am familiar with "cheater vent" It be to a option but certain if local code allows them here. No Gurgles so probably ok at that place. I did endeavor to have my plumber telescopic the drain when I remodeled the kitchen but he couldn't get far. Now I know why looking at the rats nest of pipe (posted beneath).

I wanted nether the slab wall checked and He tried from the cap that popped off (bottom one ). Want I can't figure out is what is that second pipe (upper) going under the slab towards the kitchen? I had the room stripped to bare walls and in that location is simply ONE drain in the kitchen. Naught else is that requires plumbing is in the expanse.

@Old Home,

If venting were the issue you'd probably hear gurgling drains; in any event yous could endeavor a "cheater vent" like those described at

AIR ADMITTANCE VALVES AAVs https://inspectapedia.com/plumbing/Air_Admittance_Studor_Vents.php

You could too have the drains scoped with a sewer line photographic camera to be sure y'all understand the condition of the pipe and the problem.

I've wasted money before paying plumbers to "snake" old cast iron and galvanized fe drains to no avail when what was really needed was bleed replacment because the pipes were badly clogged with scale and worse, thick rust build-upward.

may exist of help

I originally posted some questions in the drywell section thinking information technology may of been my issue. Information technology wasn't. After advice and my inspection I found bandage steel pipes Passing shut to (simply not attached) to an abased drywell.

Groundwork: this is an belatedly 40s-early 50s house, on a slab, ciderblock walls with stucco inside and out. Dwelling house used to be on a septic system but changed to metropolis service sometime prior to 1999. I accept found both terra cotta clay pipes 4" and cast fe/steel pipes two" on the waste drains outside.

Bathrooms drain to the four" at the one cease of the house (closest to city connection) and the kitchen and washer at the other end have a Cast ii" drain. Haven't plant where the two connect nevertheless.

My problem is the kitchen/washer room two" cast pipes are very slow draining, very rusty and some of the tee and wye joints have rusted thru. I institute the trouble when a cleanout plug rusted thru and soapy water from the washer bubbled up.

I have dug up the problem area and plan to replace as much cast pipe with PVC every bit possible (about 60 feet). Hopefully none of the pipe under the slab or in the wall is bad. Major issues if they practise! Any additional suggestions would be helpful.

When I had the kitchen and laundry updated I had some questions of proper venting in the kitchen (the laundry had None! Laundry was replumbed with proper traps and a roof vent. The kitchen sink is on an exterior wall nether a window then the roof stack is possibly 3' off to the side of the sink.

When they chipped abroad the wall to replace the Galv. water pipes with PEX I saw what appeared to be a loop vent organisation using 2" Galv pipe but that'south only a guess. Also the sink drain pipe is very low, perhaps 12" above the slab. Equally a result my sink trap lis ike 2" above the chiffonier floor. Non ideal. Any idea's and suggestions would be appreciated.

I accept some pics merely have had trouble posting them on the site.

@Gladys,

To protect reader trust in this website we don't sell any product nor whatever service. Y'all will want to call some local plumbers. If a question arises about the cause or perfect cure for the impairment that your building will exist glad to exercise what nosotros tin to assistance you answer that.

I can tell hyou that while plumbing costs vary widely by country and city within land, in the U.S. you lot tin figure a ballpark toll to replace

basement cast iron drain pipe of about $175./ft.

Impairment Bandage iron pipes in basement Leaking near impairment h2o heater .How much estimated to replace?

I would have to see the line both outside and inside to be confident that I know what it is, notwithstanding it was a time when people would connect downspout lines to a cast-iron line that went into the building and out through a sewer line.

I had a downwards spout removed from the side of my house and it exposed a big bandage iron pipe that's open simply sticking out of the side of my house. What the heck is information technology and should it exist covered and so rodents don't get in.
No clue

RK asked

I am searching for standard weight chart of bandage iron spun soul waste pipes. I am requesting yous for providing the aforementioned.

Moderator answer:

Steeltubesindia.net says

Size: diameter (inch) length (feet) weight (pounds)

2 x 5 5 25.0

3 10 5 five 44.4

4 x v 5 59.6

That looks equally if we're joining lead to cast atomic number 26 and perhaps there was a cleanout - I tin can't see enough to be sure.

From the grey piping above the cast iron hub, probably lead, mayhap this is a cleanout beneath a toilet bend.

Watch out: an open up sewer line in a building risks both escape of pathogens ( a health risk) and methyl hydride gas (an explosion adventure).

What was this fitting for?information technology has 2" pipe that goes up thru roof all by itself and a 3/4 leg on the bottom? It can't exist a drain? I don't know what the broken role was? Information technology is in kitchen wall of an quondam apartment bldg.2 story bldg

Chris I'm deplorable but I don't accept a clear motion picture of your situation.

I can say in general that a main edifice drain on a residential property is very likely to be larger than ii ID and that it's normal for smaller drain lines such every bit from sinks, showers, tubs, (oftentimes 1 1/2" to 2" in diameter) to join a four" ID or larger sewer line.

I take 2" bandage iron piping that splits off , ane to my kitchen, and one to my bathroom, laundry. I've bout upwardly the concrete floor to where the Y connection is.

Tin can you tell me the pipage from there that leaves the business firm, is it three" , I need to replace the whole kitchen 2" pipage to the Y connection so I thought I would also replace the Y connector with PVC also. Does 3" pipe come into my house and will I detect a iii" connector that splits off into 2" pipes? Whatever help would be appreciated, thanks. Chris

We have a ane story commercial building that is 20 years onetime. We operate equally a eatery. Recently nosotros realized that we had a sewer gas problem and a plumber came in and replaced 3 areas of vent piping that had either cracked or rotted. We are still chasing at least one if not more leaks, and also wonder if nosotros detect them whether new ones will show up.

Replacing the entire vent arrangement would be devastating to the edifice interior walls (10+ water closets, 12 sinks, dishwasher station all continued). Is at that place a reliable fashion to reline the vent pipes or other suggestions that you may have? Thank y'all.

Nate

If you demand to get Across careful visual inspection I think you would want to contact a company that provides equipment for electronic survey of existing Pipelines. For a small-scale-scale project that's not going to be toll constructive but perhaps in your situation it would be appropriate.

What is a quick method of determining if the cast iron waste pipe delivered to a job has been damaged in transit

Yeah plumber coming over to morrow. We have a cast iron and copper connection leaking. The copper pipe may really have warn out or the alleged atomic number 82 seal.

Had to get some one certified to work with this "chancy material", and from this article the sewer gases sound like a problem. At that place is that rust and rot of the metal, the brownish color might actually be a reaction that produces hydrogen, I would guess, because the smell was indeed pretty nasty. I guess information technology is simple enough to ready, now after watching these repairs or others. Yes, a trivial nasty work though for certain and would not want to breath whatsoever of that.

It seems similar the copper pipe could be cut and a replacement put in place with gaskets on both sides accordingly. There is a galvanized nipple, coming off a copper and brass supply line for the toilet, information technology is likewise shut to the junction of the copper and cast that is leaking, affair of fact they practice touch and this volition need to be dealt with likewise, that is a bummer.

It volition need to be bent over, well cut and sauder to just motility it over a slight amount half inch or and so, will have to supplant the old nipple and toilet supply connection. So that is some other bummer for certain.

Anon:

Then conspicuously there is a drain line leak that needs repair; A drain blockage can besides brand leaks testify up where they were not previously noticed. So I think yous desire help from a plumber; Depending on the cause of the leak, its location, and the condition of the piping, temporary repair or emergency repair might exist possible with a clamp-around drain line leak fitting. Keep me posted.

which pipe is all-time between galvanized and pvc pipe for cool h2o supply

Reply:

Betimes, if you are connecting a plastic pipe to any metal, y'all don't need an intermediate diaelectric fitting. The plastic is basically non-conductive.

You only need to install special diaelectric fittings (or brass, for instance) between dissimilar metals - so you wouldn't go directly from iron pipe to copper without using an intermediate plumbing equipment, either a special diaelectric fitting (those have built-in plastic insulation components) or a brass fitting.

I accept wet on my slab floor around the sewer pipe where information technology comes out of the slab. The piping is completely dry out and shows no sign of water leaking down to the floor. anyone out there accept an thought?

Answer:

Richard,

If the drain itself is dry out and so mayhap
- there is water nether the slab that is leaking up effectually the drain insertion point
- you lot had a h2o leak that ran beyond the flooring, collected around the drain, but the run-path had dried

Reader follow-upward:

No, the moisture definitely moves abroad from the pipe and the flooring isn't moisture, simply slightly damp. Had the line tested and the water didn't back up in the pipe. Just every bit shortly as I started the shower again the dampness started to prove up. Roto Rooter thought that the elbow nether the concrete was probably corroded.
Does this sound right and should I get a 2d opinion?

Reply:

Richard,
Connecting the water appearance with the shower operation was a central diagnostic step.

Water may exist entering the flooring effectually the shower drain, or from a bad trap, or even from another shower leak point, post-obit the drain to the indicate of leave at the floor drain.

Inspect the shower drain carefully, removing information technology's grate if you tin, so every bit to check besides for leaks around the drain flange.

Reader follow-up:

(Nov 28, 2022) Richard Young said:

It doesn't matter whether it's the shower on the starting time floor or the second flooring. The drain pipe is dry on the outside all the manner down into the basement every bit far as the concrete slab. The last part of the sewer pipe that shows above the slab is a flange and that is dry out on the exterior also. No h2o shows except as moisture on the surface of the slab.

John, I'm not a corrosion practiced, only I recollect the safest bet would be to

1. gently clean off surface rust from the gas pipe

2. spray the exposed metal surfaces with an expoxy paint

three. follow British Gas' advice permitting covering the piping with concrete

Question: Why would contractor place black glue (abs?) down bandage iron shower drain?

(Sept 3, 2022) Lilia said:
Why would contractor place black glue (abs?) down cast atomic number 26 shower bleed? New bathroom and plumbing for new building - horrible smell emanating from shower. Contractor added new vent after violent into newly painted drywall - to no avail. And so coated mucilage downward the shower drain - yet bad smell slightly reduced. Then added 2nd application of the glue - scent seems to exist gone but I am worried that this is just covering a bigger problem. Even though this is a new installation the shower bleed is badly rusted and the screws on the shower drain cover rusted through. This bath is merely about 3 months old. Would a qualified plumber with a camera be able to diagnose this problem?

Reply:

Sounds odd to me too, perhaps thinking s/he is sealing a leak or deodorizing the drain but really risking a costly clog problem.

(Sept 7, 2022) Lilia said:
Dan thanks for your feedback. Would like to add together that since the last comment I did accept a plumber inspect. He pulled out an ABS sleeve out of the line for shower before the trap above and before the drain. He could see a 2" hole in side of the 2" ABS between trap and drain (possible wrong vent). Wasn't certain it the sleeve was covering up a pigsty and at that place was besides much glue to meet the problem. In order to run across the problem the make new marble tiles on shower floor demand to be pulled out and beneath excavated simply to inspect further.

Nice going Lilia. So evidently someone tried to patch a significant hole in the bandage iron drain line by inserting a plastic sleeve.

Mando,

I"m not famliar with the arroyo of drilling holes into an existing cast iron drain - interesting. How volition you seal them later?

Nearly the sludge, if the sludge is actually sewage deposits (and not corrosion for example) it sounds to me as if the main drain was blocked, partly blocked, or lacked adequate slope.
