DavidH77 Posted March 17, 2019 Report Share Posted March 17, 2019 My variable speed pump has started to have problems when it switches from high speed to low speed. We have full flow at high speed but now we have nothing at low speed. There seems to be a lot of air getting in there but I have no idea how. Any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
