No water from fresh water tank
« on: April 01, 2022, 09:36:15 PM »
Hi All,

So I filled my fresh water tank today to clean rinse, I turned on the pump and no water is coming from the faucets. I can here the water running through the pump but nothing is coming out. I have attached a Pic of the Red Hat valve attached to the out let. Could this have failed?

Hi again

So when I turn on the pump, it just runs, even with all the faucets closed, water is running constantly

Did you turn the fill switch off? If it is off, then possibly the red hat valve is stuck open. Tap on valve lightly with screwdriver to get it to close. If you need to replace valve, replace with 100psi valve. The original was 40psi. Hope this helps.

The red hat valve is likely stuck open which allows the pump to run water in a circle and never build pressure
Try tapping on the red hat valve to get it to close again

Hope this helps

Thank you everybody, will give that a try, they are not cheap! What does that valve do exactly?

No luck, tapped it and the water just ran in a circle, add that to the list of repairs, thank you

See rebuild kit part number on red hat valve tag (yours is rated for 100 psi). part number 302373.
 https://store.flw.com/products/asco-rebuild-kit-302373.html

Likely the solenoid is ok, but the diaphragm is old and perforated. Your coach somewhere has a Fill switch that is used when hooked up to city water to fill your water tank.

Bill,

So the tank fills okay and doesn't shut off automatically which is okay, I just it fill up. So I watched YouTube videos about replacing the parts inside, pretty straight forward, amazing what the small parts for the rebuild kit cost. Think I will take apart and clean and look it over. To pull out the entire device would be quite a chore, almost built into the floor behind kitchen drawers under the stove top. Thank you for the help.

Jason,
If you have a outside faucet make sure the valves are turned off. Had that happen to me twice.
