Water pump issues(?)

Hi all,
I have a 2018 Escape 19.
I am un-winterizing and when I filled the water tank and turned on the pump (after using city water and purging system) the pump cycles after I turn everything off. It appears that air bubbles are in the "out" side of the pump by viewing the clear line. I have taken off the clear screen filter and inspected and reinstalled it, making sure it was hand tight. I can see no areas that are wet but I can hear air sucking into the system. When I take the hot water tank off-line the air noise stops and the pump still cycles, but more quickly.
I've also tightened all of the hose clamps going into the water pump itself.

With hot water tank on-line the pump cycles about every 10 seconds, with tank off line it cycles about every 2 or 3 seconds.
Do you have any suggestions?


No wet areas to be found, unable to tell where air sound is coming from but generally sounds like water heater area. As most of you know it is a small space so located a sound can be a problem. Pump still cycles with water heater off line

Is the hot water tank full or is that what you mean by a full water tank?

Yes, water heater is full. I filled and purged the system with city water before trying the pump

Is this the 1st time you've dewinterized the trailer? We've seen them with the HW tank bypass valves installed wrong so I'm wondering if it's worked correctly in the past.

We've had our 19 since September of 2017. I winterized and had no trouble for the 2018 season. It seems to me that somehow air is being leaked into the pump or pump fixtures. I can hear a little air hiss sometimes but can't really tell where it is coming from

Just so you know that 2 ft x 3 ft plywood bed deck above the pump unscrews real quick if you need a better look.

thanks, got the bed propped up and the little panel removed.
I've tried to reasonably tighten all the fixtures and even tried the pump priming process that Escape has on you tube.

One possibly and one suggestion.

Inside the city water fill fitting is a check valve to prevent pressurized water from squirting out the fitting. As part of your recent procedure you may have caused the check valve to become unseated. Run the pump and see if any water is squirting out of the fitting. If so,
After you have relieved all pressure from the system, use a pencil eraser and very, very gently push the center button in and out.
If this proves to be the source of the problem and if you can’t reset the check valve, you can buy a plug at the neighborhood hardware store as a temporary / permanent fix.

Suggestion.
We just finished a three week sea trial with our new 21. Dave Warren is the head man of parts and service. A major source of good info. He helped me out several times.
He is at extension 117 or e-mail at

Take care

Ed

Thanks to Ed for another option
I found the check valve behind the screen on the city water fill side. After pressing the valve I got water to come out under pressure. Then I turned on the pump and tried to press the valve again and again got water to come out. The valve seems to seal effectively as there was no squirting or dribbling with the pump running.
A big clue to me seems to be the air bubble on the outlet side of the pump. To me it suggests that there is air either in the pump or leaking into the pump somehow.
Learning a lot in this process.
I've already had one reply from Dave who suggested watching the video on purging the pump. I did that and also decreased the pressure switch by 1/2 turn as a second step. Still have the issue.
Dave may have another idea but I'm trying everything right now - thanks very much for your help

"I got water to come out under pressure. "

Going forward, never press the tip of the check valve unless all pressure has been removed from the system by opening faucets. Doing so while the system is pressurized is a common way of breaking the interior of the valve. I did that once before and replacing the check valve is a project to be avoided.

Good luck, but if Dave can't help it's a certainty that I can't.
