Plumbing question

[tractorface]

I am in the process of plumbing the basement bathroom. My house was built in 2004 and has a rough in for the basement bathroom. The rough in is for a system with a sewage ejector pump since the drain line leaving the house to the septic system is higher than the basement slab. I have a cast iron sewage ejector pump ready to go.



My question is about the rubber grommets that are used on the lid to the sewage pit. Are these grommets going to keep the sewer gas in?? Also Should I simply stick the 2" vent pipe through the grommet and not "terminate" it in any way. I am thinking leaving it in about 1" is the way to go but would feel better if I could terminate it solidly somehow. I plan to install my check valve Horizontally any comments?

Last question is with the lid. Do I simply bolt it on using the hardware supplied or should I seal it with RTV. Hoping not to have to get back in very often :-laf



Ho maitenace free are these systems? Any tips or tricks would be appreciated. I am going to add a high level alarm also.

Thanks in advance

To answer your first question the grommets will keep the sewer gases in... providing you are using the correct diameter pipe, you will know you are by the difficulty in putting the pipe thru. What do you mean by terminate? It is best to place the check valve verticle and the lid should have a rubber seal, if not just use clear latex caulk... make sure the surface is clean. If you could describe a little better the system you are using i may be able to help more.

What EDunford says.

The vent through the lid will be fine, just be sure it has some type of support where it is turning down to keep the strain off that fitting. I would also suggest you put the check valve just high enough to get the lid off for service and then put a pvc ball above that in case the check valve goes bad or has something in the flapper portion. Installing the check valve horizontally is ok, although we always did them vertically.

The crock should come with a rubber/foam type of seal to seal the lid with, you can also use some silicone or other type of caulk to seal it as well.

Ahh. Missing the rubber seal. I thought it needed something.

OK, I'll install check valve vertically. I have a 2" ball valve as well. Up to this point I have been going by pictures of systems. Thanks for the replies. I will stop by the plumbing supply house and see if they have a rubber gasket. That will make re-entry less of a pain.



By terminate, I mean solidly mount, maybe with a TA and locknut or something. I'll stick with the rubber seal.

I am an Electrician by trade, so I have seen plenty of Plumbers plumbing :-laf



Yep I want to keep the sewer gas in :-laf Thanks
