I live in an area where this is allowed.
Every other place I worked it was not allowed.

How do you do this? Adaptors from the 4" slotted pipe to a P trap to the sewer line, a back-up valve in there some place?

Thinking maybe better to have a sump pump connected to the weeping tile, then the pump to a standing pipe with a P-trap, sort of like a washer drain.

Thanks for any help.

The washer drain method you described has the advantage that if the sewer backs up, it won't bring sewage into your weeping tiles and up into your basement should the check valve be held ajar by debris.

The advantage of draining the weeping tiles (or sump pump pit) directly into the sewer (slope permitting) is that the system still works if there is a power failure.

lol, it never can be a straightforward thing!

Talked to a carpenter who has been here for years, grew up here and is retired now. Says all the ones he knows of use a stand pipe.
