I'm installing a sewage ejector pump in my basement.
I need to install a check valve between the pump and the sewer line.
The pump manual says to mount the check valve horizontally to avoid solids settling atop the valve and causing it to stick.
However, I purchased a rigid pvc cv that seems much sturdier than the 'economy' cv the pump mfg recommends using. The pvc valve mfg says it can be installed vertically or horizontally. In fact, they say vertically is better because it lets gravity work better to seal the valve AND it actually says the column of water atop the valve is a good thing for preventing b-flow and won't cause the valve to seal or a pump to burnout.
Who do I believe? The pump manufacturer or the valve manufacturer? BTW, I'm partial to vertical installation bkz it'll make removing the pump for servicing easier in the long run.
Also, my pump is about 10 horiz feet from the stack. Any problem with lifting the discharge straight up, and running 10feet horiz (with appropriate pitch) to the sewer (or do I have to position the pump as close underneath the sewer outlet as possible?)
I'm using a 2hp / 2"discharge pump.
