Re: Basement shower sewer smell


did they camera main drain?
what about washer drain?
that pumping action could siphon shower if
those two drains tie together & vent
for shower location/function questionable

Peace

Re: Basement shower sewer smell


you can test yourself,
next time before your washer dumps,
go to shower drain w/flashlight &
watch if trap level fluctuates up/down
as pumping action is created by washer

Does sink drain easily handle all water discharged from washer without backup?

Peace

Yeah I see the water just vibrate a little but doesn't look like it goes up or down.

But, I measured the water then went to bed with no activity over night and measured in the morning and it was like 3 inches lower. I think it has to be a slow leak.

My neighbor does concrete. Would a plumber work with me on this so I can save money.

I dig it out.
Plumber fixes pipe
I put dirt back and concrete

finished showers have pans incorporated into drainage...
are saying this is a rough concrete floor (without any tiling)?

Ok yeah I thought there are pans. This shower floor has tiles. I assume the pan is under the tiles?

yes & pan incorporates/rolls up behind tile shower's vertical surfaces along with threshold...
therefore entire bottom 1/3 of shower will need replacing (if not entire shower)...
I've done this for older clients on budget when pan failed
but it is a pain and most tile contractors would not even consider this ...
they get paid to put in tile & there is more money involved with gutting shower = more tile...

Ah got it. Man this is bad timing. I can't sell the house this way.

I spoke with my realtor and she said to fix it and she will mention it to buyer and say we did fix it.

But I wonder if they would want to be involved as they may want to just retile the whole shower and not just the bottom 1/3.

The person buying the house is a 29 year girl. I do not want to put her in a bad spot with this issue, so I do want to do the right thing. Just hope this does not make her back out.

Re: Basement shower sewer smell


Christian, let's start from the other end & work backwards. That drain is supposed to go into the city sewer or into a septic tank. However, in some early builds, the drains went directly into the ground or a line into the gutter near the curb. Have you traced that line to the end wherever it may take you? Do the other showers drain into a visible 4" pipe?

Re: Basement shower sewer smell


try the vegetable oil test
Pour at least 8 oz into trap
& monitor level for week
while communicating forward

knocking off value of new shower
may be acceptable to new buyer
especially since drain can be plugged in interim

Peace

It does drain to the city sewer. Near the sidewalk there is a 4" pipe. When I run shower I can put my ear to it and here water.

The up stairs shower drains into a 2" pipe then over to a large cast iron vertical stack.

I can't see where the basement pipe goes into.

Ok I'll try the oil.

Thanks

Re: Basement shower sewer smell


For the record, you should use mineral oil and not vegetable oil in a seldom used trap. The vegetable oil can and does go rancid and will smell just as bad as the sewer gas!
For a basement shower that is rarely used, is it really worth the expense to bust up the concrete to look for a leak that may or may not even be there? If it was me, I'd go with the $30 trap guard, disclose it to the buyer and call it done.

Re: Basement shower sewer smell


Christian, where the basement pipe goes is most important. Can you obtain a plumbing plan?

I did a test last night. Measured the water level in the trap. Went to bed. Then checked it in the morning. We did not run water or flush any toilets. It went down just over 1 inch in 6 hrs.

If it's going down without running water or flushing toilet or doing wash It has to be a leak?

I'm not sure where to get the plans to show where/how the pipes run.
