Common Faults & Methods

2, The pump works, but with small flow and low pressure: shorten the inlet/outlet water pipe length; change to high power adaptor or high capacity battery.

3, The pressure will reduce after years of usage: change pump head or pump head bracket, membrane.

4, Can’t suck after long time idle: pour some water into inlet.
