Frequently Asked Questions (FAQs)
(Oct 31, 2011) Alex in Seattle said:
the sewer line that comes through the foundation wall has a large irregular hole around it. the space between the copper sewer line and foundation is between 2" and 6". It was crudely made. I have water seeping in here and would like to seal it. If it was smaller I'd use hydrolic cement, but it seems to large. Can I fill the hole with regular cement and call it good? I'll use a bonding agent. Or I was thinking of doing some sort of sleeve that would allow the pipe to move a bit if needed.
I was thinking of wrapping the pipe with rope and then taping plastic over the rope. fill the hole with cement. after the cure, then pull out the rope and the plastic. should give me some space between the cement and the pipe. seal this space with a high quality sealant or spray foam. Any thoughts or ideas would be helpful. I can't seem to find any helpful info on this issue. Thanks.

I have a septic system with a house on blocks that I can crawl under. We have two toilets downstairs discharging into a 3 inch PVC with a 3 inch vent pipe going upstairs and venting outside the house. I want to add one more toilet in an up-stair bathroom and I want to discharge it into the 3 inch vent pipe - will i have any problems if I do this?

What would be the acceptable limit for foundation settling before
it would seriously affect the pitch of the drain pipe leading to
There's no smart succinct "right" answer to the question as you post it.
Any settlement that results in loss of the proper minimum pitch of 1/8 to 1/4" per foot in the drain line can lead to clogging.
I'd be worried that settlement might also break a sub-slab drain line leading to leaks, blockages, and possibly unsanitary condtions. Some investigation is in order. YOu could start by having a plumber send a camera through the line.
I'd also want to know the cause of settlement and what else it may have affected.
