I live in NJ. Does the plumbing code indicate that a basement sewage pump has to be on a separate circuit? Or, can it be on the same 20 amp circuit as the bathroom it services. The pump is rated for 15 amps.

Hi JK

Plumbing code does not say anything to do with electrical code. This question may do better over at electrical.

However, in all my years of installing these ejector pumps almost every one had its own dedicated circuit. Some of these circuits had G.F.C.I. protection... others didn't. BUT, as said, almost every one had its own dedicated circuit.

Sorry, that's all I have for now. I am sure others will be in with opinions as well. I will try to see if we can move you over to electric so they can answer the CODE question asap!

Good luck! Mark

I would say that (besides IF there are rules for a separate circuit) it much depends on what else you run in that same circuit. Do you have only lights, or do you have any (other) appliances on that same circuit?
Specially any possible start-up motor current could be a problem.
That saying : a pump rated for 15 Amps can have a starting peak current double of that, though this is only for less than a second.
It would be wise to upgrade your breaker to accommodate that start-up current pulse! Say to 30+ Amps.

A 15A pump would need a dedicated 20A circuit regardless of where it is.
It especially CANNOT be on a circuit with bathroom receptacles.
