I know this sound crazy. When I turn on my booster pump it pulls water instead of blowing water. Nothing has changed Wiring still the same. Has not been wired backwards. Any help will be appreciated. Thanks
A better photo of where those 2 hoses connect to the plumbing would be helpful if you can post those.Last year everything worked fine there was no changes to anything since then. Opened pool now water jet (for vacuum) pushes water out just fine till I turn the booster pump on. Then the line flow reverses and pulls water.
