I have a utility sink in the basement which the washing machine drains into. I just installed this sink and used a Hydromatic HPUSP125 pump on the recommendation of another forum member.
The install went fine, but when the sink has water in it, the pump cycles on/off and can't empty the sink.
The pump has two plugs, a diaphragm switch with a piggyback outlet plug, and the actual pump plug. I've got it plugged in correctly, with the piggyback plug. If I unplug the switch and plug the pump directly into the wall, the pump runs great and is able to keep up with the washing machine discharge just fine, and pumps out the sink.
This is with the ball valve totally open. If I adjust the ball valve on the discharge line to about 70% closed, the pump will run continuously also(plugged into the switch correctly), but at 70% closed, the pump isn't emptying the sink fast enough and it overflows.
Could this be a bad switch? Why wouldn't the pump run continuously with a sink full of water and the ball valve 100% open?
Any help is appreciated. My wife would really like to do some laundry
