Is this pump self-priming?

The pump is self priming once it is submerged into the water and the water level starts the pump.

Wayne Pump Expert· 11 years ago
When the pump is placed in a sump pit and water is introduced through the discharge piping into the pit the pump will prime itself.
Sump pumps do not have a specific port to let water in-ours have multiple openings in the volute above the impeller to let the water in and be pumped out.Helpful?

Does Model# CDU800 come with an electrical cord?
Is there a check valve that prevents flow back into the pump and pool that goes with this model?

Mopic· 11 years ago
The pump comes with an electrical cord but not with a check valve to prevent flow back. You can get a check valve at any hardware store & install it very easly.

This pump is not good for recirculating water because it is not a continuous duty pump. I would suggest a fountain pump and I have listed a few options below.
