I'm going to open the floor of my basement to put in a sump pit. The weeping
tile system is connected directly to my sewer main. I know where it connects
(a y-connector was discovered near the main clean out by video inspection)
and that where I'm going to put the pit. Once I get the floor open and the
pipe excavated what's the best way to cut through the 4" weeping tile pipe?
I'm guessing it's probably cast iron. House was built in '66. Thx.

Why are you putting in a sump where you already have natural
gravitational drainage?

Does this Y have a backflow preventer so sewer clogs don't infest the
drain tiles?

at this point in your basement I would be surprised if the pipe is
weeping tile pipe. I would expect it to be regular pipe, but im no expert.

If the main line plugs or backflows I'm in big trouble. I'm also putting in
a backflow valve inside the house and probably going to put in a shut off
valve outside the house. I'm going to cap the y-connector on the weeping
tile side and divert the weeping tile water into the pit and pump it onto
the yard.

To answer your question about how to cut it. Chain cutter - it wraps
around the pipe, keep tightening and the pipe snaps cleanly. You might
be able to borrow one from a plumber.

I agree with others. It is a bad idea.

And in most areas, it's illegal to discharge sump pump water into the
sewer system. Sewer water must be treated and this increases the
amount of waste water that needs to be processed. The best way usually
is to discharge it outside, away from the house.
