If I were to install a sump pump system in my brownstone basement where do I discharge the collected water? Could I use a check valve and combine it with the sanitary before the house trap. I know this is not allowed in some municipalities but my roof drain does this already. The house is a corner house so I could pump it up above grade and out through the foundation wall. There is about 4 feet of planted space before the sidewalk but I can’t imagine discharging it onto the sidewalk is allowed and dumping it into the planted zone probably doesn’t get it far enough from the house to do much good. Master plumber are you there?
I’d like to piggback on this question and ask if you could discharge the water into rain barrels out back?
Why are you adding a sump pump and what are you pumping?
True dat.
In some high-risk situations we’ve added a tee and shut off valves to divert the pumped water to a pipe leading outside.
MP can’t tell you this but in a significant weather event where the sewers are backed up dumping into the slop sink won’t get you anything. Dumping it onto the sidewalk will.
Thanks!
I’ve got a slop sink in the immediate vicinity.
Yeah, I’m here.
You can pump it into the sewer system but it has to drain indirectly into a trapped and vented fixture (a fixture can be a slop sink, funnel drain, or other waste receptacle).
You need a check valve on most pump installations.
