Hi k sifus, i am facing similar issue now where my water pump wont stop running. Noticed this issue this morning when water is scalding hot but water pressure is still strong.
Have checked all outlet in the house but no leakage. Went to the pump itself and saw leakage at the pump inlet. Does the leakage at the inlet causes the pump to run continuously? Or is there other underlying issue?

Don't think there is a valve on my pump though
