Plumbing Advice

[plutoniumJoe]

I am at a crossroads and I just want to make sure I proceed the most efficient way. My stand is done and I could move it in now but there is a drain issue that I want to think more about.

When I was removing my old sub floor I uncovered what looks like a drain or a clean-out.

I removed some of the concrete that was covering parts of the lip. At this point I am thinking it was plumbed when the foundation was poured for the possibility of a wet bar or sink and not a clean out. It would be the perfect spot for an emergency drain so that if I ever did overflow or have a disaster the water would simply go down the drain right under the tank. I am pretty certain that its pipe leads out under the wall to the garage where there is an existing function drain that I will use to drain my RO/DI water and do my water changes to. The grey rectangle show the drain direction to the wall.

The plug or cap is surrounded by hemp or whatever they used in 61 and poured lead. If I open this up am I looking for trouble or would an emergency drain be worth it?

It could be for a toilet I would have a plumber take a look at it and have them make a educated guess at what it is you could be opening a can of worms. If you could get a copy of the blue prints that would tell you city hall may have them as they would have needed a set no hand when the house was built.

An emergency drain is defenitly worth it. If it has a P-trap I would use it. if it doesn't have one I would hammer out the slab and install one.

Opening that may give you sewer gas coming up unless there is a trapp.

thats what I said

I have to say I like the spirit of adventure. If it doesn't have a P trap I will plug it until I can get a P trap in.

Bob,
Thank you for all the advice, you were patient and informative... and most of all right. The P trap was essential 90% away from where I thought the pipe was running, so inside the wall like you suggested. It was a b@*'~ to get the cap off as I couldn't grab it with anything because the whole thing was a couple of inches below grade. Eventually got it to spin by driving it with a screw driver into the brass.

So now I have an emergency drain that may save my basement and my marriage one day.

Good to hear, just remember you have a conduit for everything creepy and crawly in your garage to inside your home. Might want to plug it off in the garage. Just a thought, glad I could help,
