Overflows & Overflows

[Antique Pedaler]

Reading some of the "overflow" posts suggests I tell you about my recent experience. While on city water, backflow through the water pump would fill the freshwater tank and overflow out the breather tube. Also when boondocking, the water pump came on for a short burst every five minutes or so.

When we got home I called the manufacturer, Aquatec. The customer service tech figured I had a faulty check valve and sent me a new one. When I opened the water line at the pump outlet to remove the suspect check valve....there was none there. I installed the one sent to me and I think everything is okay now. But the long term test will come with an upcoming month long trek.

jcanavera also had a faulty check valve. Replacement seemed to also fix his similar issue (though you didn't even seem to have one).

Our pump may come on 1 time every 5-6 hours of so if that, but I agree, once every 5 minutes it way too often.

When hooked up to city water, my fresh water tank has slowly lost volume (yes, the pump is off). Is this a check valve problem? It is on a 2007 Classic.

You might check the drain valve on the bottom of the fresh water tank. I sure can't imagine why being hooked up city water would drain the fresh water tank, other than a venturi effect taking place.
