1A. Minimum sump size: 10" (254mm) diameter by 10" (254mm) depth for vertical switch models; 14" (356mm) diameter by 18" (457mm) depth for tethered switch models.

1B. Construct the sump pit of tile, concrete, steel, or plastic; it must meet code requirements.

1C. No clay, earth, sand, or gravel in the sump (they will clog the pump). Keep the pump inlet screen clear.

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.

3.Place the pump in the sump; make sure that nothing interferes with switch operation. For tethered switch models, the tether length should be 3-1/2" (See Figure 3).

4.Finish installing the necessary plumbing. Follow the glue manufacturer’s instructions for safety precautions and curing time.

Risk of flooding. Make sure the pump can- not move in the sump. If the pump moves when it runs, the piping or sump wall may interfere with the switch and prevent the pump from starting or stopping.
