What is the required pipe size for a in floor sewer pump? This pump has a 1.5 inch pipe traveling from the pump to the main waste line. Shouldn’t it be 3 inch?
Not if it is a macerator pump. It leaves no solids and only pumps a slurry.
Discharge pipe looks fine, it does need a vent pipe, however, if that is an ejector/sewer pump.
Trap mounted up and down can make a loud slam when the pump shuts off .
Recommended it is side ways for a more silent operation .
Billy, Who’s the manufacture?
Most I’m familiar with require a minimum of 2.
Lol it’s messed up either way.
If its a sump pump, most areas don’t allow it to connect to the sewer line.
If its a grinder pump, it’s missing a vent and a ball, or gate valve. Minimum grinder pump discharge is 1 1/4.
The only requirement is that the pipe be no smaller than the pump discharge.
You guys are rock stars. Thank you all!
What did you end up reporting?
I was curious as well, being the vent is the issue.
The “issue” depends on what kind of pump it is. It might not need a vent.
Basement sump pump? Were there any bathroom facilities in the basement? I don’t see a vent, so it may be just a ground water sump pump.
He said “floor sewer pump” in OP. I would assume that BB would know the difference between a sump pump and a sewer pump.
“floor sewer pump” is not a real term. 3 inches isn’t the required min, and it has a host of other problems. Including a missing vent possibly. I am not convinced the OP does know the difference.
The difference is that lacking a vent it does not look like an ejector pump to me.
Yeah, but since it’s discharging into the main waste line, it does not look like a sump pump to me. :mrgreen:
Billy, what is it?
That looks like a sewage pump lid to me with two holes just like in Joe’s graphic…
