Pump not pulling water from fresh water tank
City water works, however usiing the fresh water system with pump on, no water to faucets. Using winterized hose from a bucket of water, pump pulls water to faucets. Do I have a valve in the wrong position to pull from the fresh water tank?
Has anyone had a similar issue.
Thanks

Do you have a water connection that requires to flip a lever for city/tank fill? If you have separate city/ tank fill connectors you wouldn't have a lever to change. Also check for a strainer in the line from the water tank to the pump. Also make sure there's no closed valve between the winterizing valve and the tank.

Check to be sure you are getting water to the pump suction.
I have taken the pumps apart and found them full of plastic and metal shavings.
Good luck.

A leak in the vacuum side of the pump plumbing would allow air to get in
and reduce the ability of the pump to "lift" water. You would not
see a leak, was the bucket at the same height as the bottom of
your fresh water tank ? Could be a clue.

Winterizing means making ready for freezing temperatures. You drain all the water from tanks and plumbing or replace with RV antifreeze, pour some in the drain traps, and otherwise make the RV ready for long time storage.
Smart alecks who spend their winters in the south like to rub it in by professing ignorance as to the finer things of living in the temperate climates. They claim not to know what a snow shovel/blower is, winterizing, etc. I prefer it to 3 digit temperatures often found where they live.

It may have to be primed as suggested. See if there is an outside hose attachment besides the water fill or shoreline connection. Connect there if necessary to prime. Or you may simply need to open a drain hose to let water back its way through the pump to get rid of the air lock.

Check the filter on the intake side of pump coming from the fresh water tank. Every year I have to clean mine, collects dirt and crud and stops the water flow from the tank.

I had the same problem, almost a full tank showing, pump would just spin and not prime, I tried priming through the winterization hose, it would prime but when I switched the valve back, it lost prime again. I even had an RV shop check it while I was having some warranty work done. Found out the fresh tank was actually empty even though the tank showed all but the top LED lit.... DUH!

Just fixed my trailer, sane problem. My valve on the suction side had a crack that was letting air in (factory install problem in my case).
