Water Pump

On maiden trip an can't prime water pump. Spoke to Colonial and they recommended filling the tank completely and then add some pressurized air. Still not working any suggestions would be appreciated. Other than the pump the van is amazing.

Assume it's not handy to take it by dealer? Might be a dud pump or something as simple as they forgot to connect the inlet line to the pump intake. Did it ever work? Do you hear the pump running?

Can you get an eyeball and hand on the pump and verify the fittings are snug? I have a trailer, haven't got a clue where they hide the thing on the Interstates, but it should be accessible.

I have had trailers where you had to open all the faucets before it would prime, and others where I had to remove the outlet right at the pump until water started to flow. Kind of messy

Open a galley faucet and the lav faucet. If you can get access to an air compressor, insert a blow nozzle into the water fill port using a rag to plug up as much of the opening as you can. It doesn't need to be a complete seal. Then let the pump run for a bit while adding compressed air. These pumps aren't damaged by running dry for a couple of minutes like some other types of pump. The first time might take a minute or two.

Water Pump Location

The water pump is under the microwave. You have to remove the drawer under the microwave to access the water pump. It's not exactly easy to reach but if you get down on the floor you can check the fittings. The inlet side has a quick disconnect fitting on the line from water tank. That line is a clear plastic line with over braid on RH side as you look in drawer opening. Photo of what it looks like below.

Opening the facets might help.

Good luck!

Is there an in line valve that is turned in the wrong position thus bypassing the pump?

The fresh water tank is not designed to be pressurized. You could damage it with compressed air.

Not if you do it the way described above by using a rag as a method of sealing it off because you cannot get that much pressure on it. You just need to get a little bit of air pressure to force the water into the pump to get it primed.

Correct! The method described has been suggested to me personally by AS Customer Support. And it has worked for me on a couple of occasions with no ill affect.

My water pumpó supposedly self-primingó never would self-prime, until the folks at Foley RV center discovered and repaired a leak in the pump inlet line between the tank and the pump. Air was leaking in, not water leaking out, which is why I never could find it myself. If the pump is getting adequate suction and the tank is pretty full, it should self-prime without the need to add compressed air to the tank.

Side note, the more water in the tank, the less effective lift the pump needs to deal with, and the more likely it is to self-prime.

Ditto this. I also had an experience on my old SOB where the pickup tube INSIDE the tank came off. Obviously this resulted in no draw. I am not sure how AS does your pickup, but don't overlook a suction issue inside the tank.

Thanks to everyone for your input and advise. Applied a bit more pressure to the fresh water tank and was able to prime the pump.
