Good afternoon and thanks ahead of time for any suggestions. This may be long but I really need help! I searched the forums to find anyone with this same problem to no avail.

I have a BurCam model 400500 CAST IRON SUBMERSIBLE SEWAGE PUMP. 2" DISCHARGE AND 2"HANDLING CAPABILITIES. Independent MECHANICAL FLOAT SWITCH.
VORTEX DESIGN IMPELLER and 1/2 HP MOTOR, 115V. It came with the condo when we bought it newly remodeled last year. One guest bathroom and a washer drains into the basin. I knew nothing of sewage pumps until recently.

My problem is that the basin fills up sometimes (key word) and the motor kicks in but does not eject any of the waste. I have removed the basin cover and witnessed the waste water circling around like it is being pumped or waste is grinding just no water movement up and out of the basin. I few weeks ago I just unplugged the unit and let it sit and plugged it back in and it worked.

Most recently I completely drained the basin (shop vac... not fun) and vac'ed and snaked out the discharge pipe, examined the check valve, and drilled a hole in the discharge pipe in case of air lock, no dice. I did notice the check valve is intended for horizontal flow and the discharge pipe is in the vertical at that point. I intend on replacing but can't imagine that is my problem. I also know the pump is working to some point because I plugged it back in when the discharge pipe was disconnected at I witnessed the sewage geyser it created. Live and learn.

I want to do this myself. I feel I need to know how my property works. Has anyone run into this before or have any suggestions? Please let me know. My wife is getting impatient with my tinkering. Thanks!

If the pump spins - but doesn't pump you may have debris inside the pump. There may be some large rag that pump sucks in, holds it, and releases it when pump not in use for longer period. I would sugges that you remove the pump, take it outside, flip it upside down, take hose and clean it well. Then put in inside bucket full of water, plug it in, and observe the action. You could have clog in check valve as well. Check it out. Check valve should be installed right past discharge outlet on the pump. Get back to us and let us know how you did...
