I need to clean up the plumbing around the water tank and pump as it is a Hodge Podge of garden hose, rad hose, and gawd knows what else. I also want to put in a hot water bypass as well as an antifreeze line for winterizing.

Anyways my question is about how the fresh water hookup interfaces with the plumbing. Is there a one-way valve in the system? Or does the OEM pump have it built in? I'm thinking something might be in there as I had an issue the other week. I lost all water and my pump just kept going. After a crap load of debugging I saw water leaking out the fresh water hookup port. I 'pushed' the inside of it and water blasted out hard. After that my inside water returned to normal.

I really need to clean this up Smile

Well, a good start would be to replace that city water connection. That is supposed to have a working check valve.

In the early coaches with copper water systems, there was a check valve at the water pump because those pumps could not handle the 70psi that exists in some places. I don't know about the non-copper coaches.

The one thing you should pay attention to is that the hose and other parts you put in there are "drinking water safe". That means that they limited the amount of lead and toxic chemicals that might come loose.
