"The Pump", the hart of the water supply.

20200128 The water Pump

I confess I’ve been a little lax in creating blogs recently. I have been working on a very large project to revise the water purification system and the motor home. At the conclusion of the project. The pump that supplies pressure to the water system of the coach quit working.

A Relay. Provides full 15 Amps to pump, but the switch only handles a fraction of an Amp.
These relays are very small and can be hidden under vanities, behind studs or in void spaces.

Of course I did a bunch of troubleshooting, even enlisted Neil to help me. I finally decided that it was time to create a power source for the pump that included a relay. After several days of routing wires through the cupboards of the coach and hooking everything up, came the time for testing. I hit the “on” switch and nothing happened . I’m beginning to sweat a little, my handyman reputation is at stake. I pulled the cover on the strainer at the section of the pump and discovered that the section line was completely dry. Now there was water in the tank, but it wasn’t getting through the check valve. Logical conclusion: Check valve is plugged. Logical response: Remove, check valve. So I revised the inlet piping to eliminate the check valve. With my confidence renewed. I hit the on switch. Nothing happened. Now I’m really beginning to sweat. As handyman, I could be replaced, you know.

I think I do my best work. I’m asleep at night. The next morning I had a brilliant thought. We had been supplementing our water from the Tice’s house. The pressure from the hose could be keeping the pump from filling with water by blocking black pressure from the system. I walked over to the big house and turned off the water. You know it’s a little hard to flip the “on” switch with all your fingers crossed, but I managed to do it. Yes, it worked. Now I have to decide whether to put the check valve back in or not. I guess not.

The Sage Says: “What is the lesson to be learned here? It’s very possible to over analyze a problem. Occasionally you need to step back and look for the simple solution.”

Meanwhile, I will finish the two big projects I’m working on. The first is the adventures of the Abby Normal. The second is a detailed description of my new water system.
