Have a bay at my wash that has not been operational for several years, and the place is around 15 years old. So I removed the motor and pump, rebuilt both and cleaned up the stand. Put it all back together and manually pushed in the starter. No pressure showing on the gauge, and this is the best part, no water coming out in the bay. So what's going on? Since there was no pressure showing on the gauge, I thought it was bad, so put a new one on. Same thing. Pulled the discharge hose from the pump and got a nice stream coming out. Well the old hose and steel fittings must have corroded closed. But it that is so, there should be pressure showing on the gauge. The fun just never stops. And to make things easy, the bay is the farthest one away and you have to crouch down and walk on the roof trusses. And did I mention it's 90 degrees out?
