Please Help Identify Pipe
1 Attachment(s)
I would like to do a search on this forum for a leak that I have on the side of my house. However, I do not know what the pipe is called therefore, cannot do a search. Can anyone help me identify this pipe in the picture? It is in the side of the house.

Sorry for the small pic. I had to crop most of it due to pic size.

I would say it is the clean-out for you main drain line (to public sewer or private septic tank)

It is a clean-out for your main sewer as RJ stated. What is leaking? If the leak is at the cap, MAKE SURE NOTHING IS RUNNING THRU THE DRAINS, then you can either try ti tighten it a bit or remove it clean out the threads and re tighten it. If it is the glue joint then you might need a plumber. That may require cutting the pipe inside the house and running new pipe

Thanks for the replies. We are first-time homeowners and wanted to make sure this leak was not a major problem that needed to be repaired before we moved in.

It is not leaking from the outside but rather from the inside of walls. I noticed a wet spot in the slab under the brick below the pipe. Roto-rooter came out and they really counldn't find why it is leaking. It did not leak during our numerous flushing of all 3 toilets. They just told me to keep an eye on it.

Could it be rain coming in through cracks around the pipe? I can see what looks like a small crack on the right of the pipe.

mystery leak
First of all, what size is this pipe? It appears to be white (PVC) plastic, and you could expect a drain cleanout plug to be in excess of 2 inches usually. Did Roto Rooter unscrew the square plug, which does indeed appear to be a cleanout. Water that appears to be coming from inside of the walls is never good - unless it is ALSO inside of a pipe. I am in Fort Worth, but more familiar with UPC which was used in Phoenix when I was plumbing there 20 years ago. I expect plastic drain pipes to be ABS black plastic.

I thought it was rain getting in through the crack as well. However, it has not rained in the past couple of days and it has still been there this entire time.

I flushed multiple times yesterday and did not see any additional water on the foundation. However, this morning it was still there. Faucet or toilet were not used overnight as the house is still vacant. We will be moving in this weekend.

Rotorooter did unplug the cap while I flushed the toilets. He did not see anything unusual. NOTE: there is a toilet immediately over this cleanout on the second floor.

I guess the only way to find the leak is to go into the wall.

other sources for water
The D/FW area is legendary for foundation problems. I am wondering whether you have a supply leak. Does this drippage have waste water odor? If not, I have more questions. How low is this cleanout? You refer to the foundation several times. This last picture shows the line where the brick meets the foundation. I am thinking you have a supply leak and you are seeing seepage from the only visable exit point for the oversaturated area. With all water off in the house, watch the meter. Make a mark on the glass and come back in 15 minutes. If the needle has moved, you need to find out why. I don't like the implications. In the Dallas area, I have seen great hollow mini-lakes from just such leaks. Water will, of course, find some sort of an opening to escape, right. If you have determined that there is a small leak, try the homegrown stethascope approach, your ear to a drinking glass, pressed to the floor in various places around the house. First, be sure that all anglestops are turned off to reduce the complication of a tank to bowl leak or a drippy faucet. After all, if something ELSE has a small leak, it will make the needle move and you need to know where the water is coming from. Just because Roto Rooter found nothing, well, I'm shaking my head as I type. They are not noted as plumbers, and can be focussed on drains, a little tunnel vision so to speak. Let me know.

Any buckling of tile or wood floors in the house? Did the previous owners recently replace carpet or other flooring? Any signs of mold on lower edges of sheetrock or plaster? All of this can be going on under the slab, but sometimes signs will appear above, depending on whether there is any sort of a pathway for the water to escape.

I am in northwest Plano. The foundation seems to be surprisingly in good shape. We removed the entire downstairs flooring. There was tile in the area that we recently removed and no cracks were visible on the slab. A couple of days later I noticed there was a small damp area in the inside of the house. It came out maybe an inch from the baseboard. I figured it was rain coming through the brick spacer(not sure what its really called. I am referring to the first row of brick that does not have grout to allow the slab to expand or breathe) from the outside. In the picture you will notice that I put some caulk tape as a bandaid to see if that was the location of possible rain coming in.

When I say foundation I mean the actual slab. There is not a collection of water on the ground. The only water/damp area that can be seen is on the slab as the picture shows. There is no discoloration or damp areas on the outside or inside wall of the house around where this cleanout is located other than what the picture shows. There is not a bad smell either.

One of my concerns is also that since winter is coming that this leak will become a geiser.

Thanks for the heads up regarding RR. Perhaps I can call a 'plumber' after doing what you recommended with the water meter test.

When you say brick spacer do you mean weep hole? There are suppose to be weep holes between the bottom bricks to allow moisture to weep out so it doesn't stay in your walls. Brick walls are very permeable so water easily goes through to the inside when it rains. The weep holes are essential to letting this water get back out. Whatever you do, don't plug the weep holes or you'll trap the water in the wall.

Thanks, jogr. I only put that there for a day. Its no longer there.
