Unhappy Potable water pump keeps running


https://photos.app.goo.gl/qVfVmWSaq7qjGShV6

I have a two fold problem. When I turn the water on for street water the pump causing it to go to the storage tanks runs. The on/off switch isn't turning off.
I left for 4 days and came back to my interior pump not shutting off when I turn off the faucet inside, and the pressure is lousy.
I will admit, I took a shower before I left and found I ran my fresh water tanks out (forgot I used water bathing the dog the day before) at the end of the shower. They're full now, but have the problem.
Is there a way to prime the pump?

Is your tank fill sporlan valve stuck open? That was my first thought when, I think, you said it is running and recirculating back to the storage tanks.

Pump seals could be dead from running dry.

What does the sporlan look like? I have a part that looks like a thermostat for a car, right at the entrance where the hose screws on.

no, those are check valves on your water fill. Search here on WOG and you will find photos of sporlan
It looks like a brass plumbing tee with a ribbed black ice cube attached to the center branch.
If your pump runs and you hear water pouring back in to the tank, I'd suspect the Sporlan is stuck open.

In my old PT, it was under the bed near the fill and the water tanks and prone to sticking until I rebuilt it.

Symptoms sound like your Sporlan Valve is stuck/clogged. Near your fill is the switch labeled TANK FILL. With your pump OFF and water hose disconnected...cycle this switch. Do you hear a click? After cycling say 5 times...turn to OFF. Turn pump ON inside coach...what happens?

Use the search bar on home page to search for sporlan valve...you will find service sheet on how to clean it. Valve will be located near the outlet from water tank.

Oye vey! I knew I should have had an instant hot water system put in when I had the money. The water tank is so tight in there with all the copper pipe...I can't get to anything looking like that.
unfortunately getting less than $200 a mo to live on doesn't leave anything for repairs.
I'm about to pitch a tent somewhere!

The sporlan is under the bed and not that hard to get to. You really don't have to remove the complete thing just the top part to get to the stuck part. Answers are in the data base. Search Sporlan Valve 83 FC repair.

I fixed mine. That means you'll have no trouble.

If it's under the bed it has to be near the water pump. I have a rear bath.
