Does your pump have a valve like on the bicycle tyre. You need to take a bicycle pump and pressurise to 30psi.
My Grundfos pump had continuous running issue was caused by the pressure switch needs the back pressure. After I pump the air in Now working normally again. This post has been edited by jetblast: Nov 8 2021, 02:00 PM |
