How do you get air out of water pump?

The pump expels liquid at a high pressure; however, the area of the impeller eye maintains a lower pressure. This difference causes the air bubbles within the froth to build up and “lock” near the pump entrance.

Why does my shower pump keep pulsing?

Usually this is the result of either a scaled up shower head, a blockage in the hose (if fitted) or a blockage in the shower valve. Sometimes the pulsing occurs regardless of the temperature setting on the shower. The pump is fed by gravity from a roof tank about 1.5 metres above the shower head.
