Plumber bros, I know you're out there.
Lend me your wisdom.

Renovating for the homeowner, house was built early 60s.
Western Canada, moderate climate, water table unknown.
Pictured is the old clay tile subsoil drainage running to the combined sewer beneath the house.

My issue is, the homeowners want a bathroom installed in the basement, on the upstream side of the weeping tile.
I figure this clay tile has never seen a drop of water since it was installed. The entire community is on a sort of plateau above the freshwater reservoir.

Can I (safely/legally) cut out the rusted backwater valve, P trap, and abandon the clay tile -- and connect my new drain line to the existing?

My other thought was to do the above, but dig in a sump barrel with a pump to collect any groundwater, and tie the discharge into the new sanitary stack above ground, with a new trap and check valve.

Any thoughts bros?

Second angle

Is it even legal to have your drain tile connected to the sewer anymore?
>>

Not for new construction.
But anything existing is grandfathered

Yes... Grandfather is a verb...

>>2136701
Don't destroy a grandfathered privilege. Do it right and install a separate line.

I would work around it. It looks like you cut into it already though

I personally guarantee you after 20 years there isn't a backwater valve doing its job.
Do what you want. But I suggest an ejector pit and no floor drains tied into the gravity sewer.

OP here,

Spoke with a local inspector.

He agreed that a sump pit and pump would be okay for any groundwater that may collect, but the discharge would have to go to the outside.

Because we are replacing and not repairing, current codes apply.

Not a plumber, but the general rule is that anything you do that is considered "major" must be up to modern code. Generally things can only be grandfathered for direct repairs or things inside the living space.

It is a verb though. It is in common usage and people know what it means. That's how language works. We don't need your approval for it.
