Overflowing drain pipe

I understand that it is not the washer that is the problem but the stand pipe itself, how do I fix this though?

    figured out what the problem is, my pipe is a 1 1/2"

  • nickiknocker Dec 30, 2008

    The same thing is happening to me. I've had to plumbers out. We actually replaced the drain pipe and extended the heighth thinking that would solve the problem. Nope, still overflowing. I have to constantly stand over the washer during the rinse cycle and shut it off and on so that the pipe doesn't overflow. We did buy a water pressure reducer from the hardware store that only cost $4 and it's working okay so far. We did this once before and it WILL leak again. It's only a matter of time. Instead of putting a bandaid over the problem I would actually like to fix it. One of the plumbers told me to snake the pipe on my roof. I looked at him kind of funny because I've never heard of a pipe on a roof but I actually saw it today. Has anyone ever heard of this before?

It is ok to use a stand pipe that is 1 1/2 inch. the problem is that you need a new plumber!!! really you need someone that has a drain cleaning machine and can cut through all the years of lint and debris that has built up inside the pipe.
they will use the same type of head that is used to cut out tree roots from drains. make sure they know what they are doing before you agree to pay them, most good companies will charge about 50-75 bucks to clean the drain out.
also try the unit before the plumber leaves to make sure the drain is clean and doesnt back up.

I have a Utica gas furnace and the overflow pipe is dripping continuously. What could be the problem?

If your Utica is a high efficiency 90+ condensing furnace, I suspect not too much is wrong. A condensing furnace removes so much latent heat from the burned fuel that it condenses the moisture out of the flu-gases. The result is a very low flu temperature, AND water.

The water must be flowing correctly down the proper drain though, or you could suffer damage to the furnace itself. If there is an 'overflow' pipe and it is running over though, the drain downstream must have an obstruction. Clean the drain out and the overflow situation should go away.

Drain stand pipe Washer fills and drains at same time. Manual says the drain stand pipe must be greater than 30 degrees. I would like to have a description of the drain stand pipe and it's...

30 degrees or 30 inches. The drain stand pipe is separate from the washer and usual plumbed in behind the washer. You bring the the drain hose up to the top of the standpipe and then push the end (forming an upside down U at this point) into the top of the open 2-3" diameter PVC pipe and secure it so that it won't back out (but do not seal the opening). Nylon ties or hose clamps will work. The height requirement is so that the bottom of the hose in the standpipe is above the water level in the washer - this avoids the drain siphoning the water out of the washer. Check how far into the standpipe the drain hose has been pushed. If it is below the level of the water in the washer, back it out. Check the height of the standpipe. Many washer manuals recommend a 34" standpipe (max height of 48") based on the drain hose length on the down side of the U. Also make sure no one sealed the top of the standpipe against air entering the pipe. (Often this is done because of a back up in the drain, pull the drain hose out and get the pipe cleaned out and then put the hose in to the proper distance. Then leave the top of the standpipe open.)

For a picture of the standpipe, see .

There is a parts diagram for your washer itself is here: .

I hope this helps.

When it goes through rinse cycle and starts to pump water out of the machine, the drain pipe fills up and overflows, then it will rapidly drain.

Usually there is a clog or restriction in the stand pipe(drain pipe) causing water to not drain away.....Suggest drain-O products.
If you have a very long drain or the stand pipe is not above the water level in the tub you will want some type of air gap to prevent siphoning.(siphon break kit)

good luck

LSR8233JQ0Washer won't fill

The water is syphoning out the drain hose.
Many times when the stand pipe is backing up someone will seal the washer drain hose to the pipe to avoid overflow of the stand pipe.
This causes the water to syphon from the washer.

Or the opening for the stand pipe is just big enough to put the drain hose in and is to tight causing the syphon.

Putting the drain hose to far down the pipe can cause a syphon also.

When the washer drains water comes out the stand pipe The stand pipe is just over the back of the washer. This just started about 3 loads ago.

You have a clog in one of your lines that connects to the standpipe whether it be in that pipe or another one that is close to it. You may want to check the air gap either on the side of the house or rooftop and snake that out. The standpipe itself is generally 2" in width and 48" in length. to have a plumber out you are looking at about $200.00. Did you try to google "why would my standpipe overflow?" Just a thought. I am sorry I was not any help, good luck!

When washer was off it filled up with water and overflowed will a water inlet valve fix this. this is a whilpool washer frontload ghw9100lq1

Yes, it should. The only way water can enter a washer when off, is through a stuck inlet valve, or by siphoning water from a drain hose installed too deeply in the stand pipe. If your machine had enough water coming in to overflow, that definitely sounds like a bad inlet valve.

check to see how much drain line is in the stand pipe in the wall. there should only be about a foot of drain hose in the pipe any more that that will cause a syphon efect that will suck out any water that goes in. also, the stand piper in the wall bhind washer must be as tall as the washer itself.
