Exclamation Water Pump / Pressure Problem 2017 Northpoint

I have a new 2017 Jayco NorthPoint 5th wheel. It has been winterized properly.
The problem is when running on self contained (tank water) the pump is sucking air and will not pressurize the system.
Here's the facts and troubleshooting so far:
- System works fine (no leaks) on city water pressure
- The system will not pressure up on the water pump. The pump will run and sporadically pump water mixed with a high volume of air.
- It is not a pump problem. I have tried 3 pumps.
- When testing the output of the pump (into a pail of water) the output constantly gurgles a lot of air. Run time does not help the air is continuous.
- When I use a bucket of water for my water source (to suction end of pump) the system will pressurize in seconds and operate normally.
- Through all of this, there are no water leaks, not anywhere.
- Somewhere my system is getting air to the pump input side and not allowing it to pressurize.

I've had this brand new trailer almost 4 months and it's been out of commission or in the shop for one reason or another more than I've been able to use it.

If anyone has any ideas as to where I'm getting the air; it would be most appreciated! Jayco Support usually doesn't have a clue. Their reply is "take it to the dealer". My dealer (CW) is worse than awful. They are booked for 6 weeks and say they will probably need the RV for at least 2 weeks to diagnose and fix.

I'm thinking (hoping) it's possibly one of the "water selector" valves (near the city water input. They look and feel cheap, but are next to impossible to access / get to. The factory plumbing and wiring behind that panel is an absolute unprofessional MESS (thank you Jayco).

HELP!! Where is the air coming from?? THAT is what is causing this problem.

Thank you!!

I'm just throwing this out there.
Check the check valve inside the hose connector for the city water hose to attach to.
It is to stop the pressure from coming back when your using the pump. But maybe it's stuck open and your sucking air?
Also my hose to the water pump was almost sucked flat, but it never stopped pumping. I replaced it with a solid pex pipe.

You can take the front white face plate off of the valves. Just unscrew everything. And all the plumbing is accessible. I have a picture when I took mine off, but I can't find it now.
That's all I got. Good luck.

Do you have a Girard Tankless hot water system? If so it could be that. There is a flow control on the back of that and if it's turned down too low it will cause the system to suck dry, this happened to me.

I believe (or I hope) behind that panel (where all the connections are) is where my air leak is. I unscrewed the entire panel but Jayco left NO slack in the plumbing lines. You can only pull the panel off about 3"; not enough to really see or work on it. What I can see back there is a MESS!
I checked the check valve inside the city water connection. It appears to be seated properly. When I slightly depress it (with the pump trying to pressurize) and water will spray out.

As far as water heater,... no I don't have the tankless; it's a regular 10gal Propane / Elect heater. When the pump is trying to pressure up, I'm pretty certain I can hear the tank "gurgling" from air being injected into it. Once again,.... the system works fine on city water pressure,.. no leaks. I'm not sure if those facts should be aiming me in a certain direction.

Maybe check for kinked line from the water tank.... Just throwing that out there. These problems.can be very frustrating!

Not trying to be "negative" and I DO appreciate all the replies,.. but,... I would think that there's got to be a break in the line or an open / loose connection for it to be "sucking air". I don't think just a kink would do it. The weird part is that either on city pressure or the pump nothing is leaking. I would think that if air can get sucked it that some "pressure" would allow water to leak and be seen??

These WILL NOT be the problem: Kink in the line, city water check valve.
These might be:
1. Filter bowl just before the pump inlet loose?
2. Winterizing suction line valve not fully closed?
3. Hose clamps on all connections tight between the pump and the fresh water tank?
4. Insufficient water in the fresh water tank?

I believe that the sediment filter is on the suction side of the pump, and if not screwed down tight, or with O ring not seated will suck air. If you haven't cleaned the filter in a while its worth checking anyway.
To checkbifvthere many be a pin hole in the suction hose into your fresh water tank, maybe you could disconnect that from pump and connect anothervpiece and try sucking water from a bucket. If it pressurizes then I'd suspect the tank hose.

I have the same problem and have been unable to figure out what the deal is. WE have a 2017 Jayflight 27BHS. I filled my tanks all the way and I get a good stream and then gurgling and spitting and then back to a good stream and so on.

I have checked connections, taken the filter off, cleaned it and put it back on. But, it still ends up doing the same thing.
