Sewage Pump Installation
I'm installing a sewage pump and I'm undecided as to whether I should put sealer on the threads that screw down into the vent outlet on the pump. This threaded fitting is glued to the vent pipe. If I am to ever remove the lid on the basin, I would need to remove this pipe so that I can pull the lid completely off and get to the pump. If this is sealed (at the threads) then I may need to cut the vent pipe or pull the pipe/lid up at the same time which may be tough. Anyone have suggestions?

Another related question: do I need to mount the pump to anything at the bottom of the basin? It's pretty heavy but my concern is that when it spins to pump it will turn and possibly break the exit pipe. What prevents this spin that would counteract the pump spin?

Your going to want to seal that bad boy, it's going to get smelly in there and you really don't want the wonderful fragrance floating throughout the house. The sewage ejectors I am familiar with have a removeable lid on a portion of the top thus allowing the vent pipe to not being effected by service to the motor, if such is not the case then should service be required you can simply cut the vent pipe and install a coupler at that time or use a union.

You do not need to mount the pump on anything just make sure the floats are free and clear of any obstructions down there, again, once that lid is on and sealed you really don't want to open it, it's not pretty in there after the first 'major' use.

Don't forget to use ALL the required parts on the drain side...Backflow Preventor, Union, Gate Valve.

I'm definitely going to seal it. It's confusing to me why the book says to "be sure to cut the exit pipe close to the lid for easy access" when I would have to cut the pipe itself to get to it if it were close to the lid whereas I could leave some room there and just pull the lid straight up and access if needed. I guess I can pop the lid up the rotate it around away from the hole to access the pump rather than cutting the pipe. Yes, I have a combination Check valve and Ball shutoff valve at the exit.
