Zoeller ejector not pumping
 
Hi,
The pump is humming, but not pumping (no jokes plz :jester:)
The cover to the pit is off, and the pit is almost above the intake pipes.
This is a roughed-in plumbing situation that has never been used other than the humidifier going into the floor drain...unfinished basement and bathroom...5 yr old house.

So there is water in the pit, the float switch (zoeller m211) is free to move...yet nothing. I have unplugged the pump...I couldn't tell if the pump was trying to run since the pump is 6" under water...other than the hum.

The vertical pipe that goes into the house sewer pipes seems full of water, again hard to tell...just tapped on it.

The pipe goes to the joists, over to the perimeter and into the larger6" pipe to the sewer. When I run a sink upstairs I can hear water trickling into the 6" pipe.

So can it be vapor lock only in the 2" pipe? A blockage?

What is the best way to troubleshoot? The ejector pipe has no cleanout, and the closest cleanout is a foot upstream from the 2" pipe going into the 6" pipe.

There is a valve that is about 2' above the pit.....I will post a picture when I can....does it look like the valve can be loosened to let water out and release the vapor lock, if that is it?

Before I put a pipe wrench to the bottom of the valve....I would like to know that it is threaded and not a glued joint if anyone knows.

Thanks...I figure I have 2 days before this overflows.....

If it's running --it will make noise and get hot----
If that is the case your back flow valve might be jammed.

If the pump is not running---could be the power to that outlet is off--check the outlet-

Pump or switch on the pump could be broken---if so replace the pump.

Post a picture if you can--someone here will tell you how to easily change yours.

picture of valve....
Can I loosen the bottom of this...is anyone familiar?

There is a hum when I plug the pump back in, but I haven't reached in to feel any vibration on the pump...yet.

Thanks.

Typical set up---

If that pit is only used for clear drain water you could use a sump pump instead of the more expensive sewage pump--

You will need two--2" rubber Fernco couplings
A pump

A threaded adapter to fit the new pump in 2"

A piece of 2" pipe about 3 feet long

Pvc primer and pvc cement--

Saw and a screw driver.

turn the blue handle on the back flow valve---

cut the pipe about 4" below the valve.

Cut the vent pipe at about the same height--

Remove the pump and lid--Clean the pit if it needs it.

Add the fitting and length of pipe to the new pump--

lower it into the pit---cut the pipe to match the pipe coming off the back flow valve

position the pump so the float works without hitting the wall of the pit.

Install the lid--add the gaskets for the lid/pipe---

Install and tighten the rubber Fernco coupling to the pump piping and the cut off vent pipe.

Turn the blue handle back on--


test the new pump

Thanks for the step-by-step....

Im not sure what I will replace it with...not sure WHEN it will be a functioning bathroom (i.e. finished).

The bottom flange of the shutoff valve loosened by hand...so I disconnected the pipe ...plugged in the pump pump...pump hums...and nothing. Zoeller even disse'd the pump saying it was a low end (new construction) pump. 1 year warranty. nice quality construction..lol, not.

Bummer.

Thanks for the help, I was hopeful it was something less costly.

I've had ejector pumps suck up a piece of gravel and jamb.

I pulled out the gravel---pump was fine---then I cleaned the pit---and reinstalled the pump.

I suggest a sump pump-get an ejector if and when you build that bathroom.

well....it was frozen, but after turning it by hand several times....it now runs....now what? replace or keep it?

Update:
According to Zoeller...a gasket on the impeller shaft can sometimes allow grime to build up and prevent the pump from spinning (very low torque motor).

Suggestion was to soak the pump in vinegar overnight.....If this works, maybe I'll do this once every couple of months.
