2A. Install the discharge plumbing and check valve, using teflon tape - NOT pipe joint compound.

2B. Tighten the pipe into the pump (hand tight + 1-1/2 turns).

2C. Install a check valve in the vertical pipe to prevent flow backwards through the pump when it shuts off. To prevent airlocking the pump, drill a 1/8" (3.2 mm) hole in the discharge pipe just above where it screws into the pump discharge. Install the check valve above this hole, but keep it as close to the pump as possible. Be sure the hole is below the waterline and below the check valve.

2D.To reduce noise and vibration, cut the discharge pipe near the pump and fasten a short length of rubber hose (1-7/8" (48 mm) I.D., e.g. radiator hose) into it with hose clamps.
