In reply to Sump Pump Discharge by Steve on June 14th, 1998 01:57 PM [Go to top of thread]

The problem is only in the elevation and distance of run on the 1 1/2" pipe.
1/ Find out your total elevation from the pump to the highest point at which the discharge can free flow.
2/ Find out the total distance of the run from the pump to the point at which the discharge can free flow.
3/ consult the pump MFG. to find out if you have the proper pump for your elevation and distance of run.
4/The pipe size is based on the discharge size of the pump.
5/You should always install a check valve near the pump so the pumped water that remains in the line will not back up.
6/ Drill a small hole in the pipe below the check valve near the base of the pump to allow the water below the check valve to drain back.
7/ Install Fustat on the electrical box where you are pluging in the pump (your furnace should have one, look at it and you will see what I'm talking about) This is hardware store item and easy to install. The fuse should be one size larger in AMPS than the AMPS of your sump pump.
This is a Fuse designed to take stress off the pump motor as it pulls the load while it starts.
8/ I would also in install clean out in the discharge line after the check valve, even though your only pumping water. Strap and brace all piping as necessary.
Good Luck,
