Air in water lines

I put fresh water into my rig for the first time. It is a brand new fleetwood 28S 2013. I cannot get the air out of the lines. I've checked all the faucets, plugs and valves to ensure they are closed. But the water pump runs when all are closed so air is getting in somewhere. Any suggestions as to how I can track this down. ( All faucets have air in them when opened one at a time.)

Thanks!

I would start with the faucet farthest from the water pump and run it until there is no more air. Then do the next to the closest. Do both hot and cold (one at a time).
Don't forget the outside faucets, shower, tank flushes, etc.
Don't drain the water tank dry (suck air) or you must start again.

Check your drain valves. Should be closed. Also check you bathroom.
If the system is full and pump is running with nothing on, you might have a water leak somewhere.

Make sure the suction hose is not kinked, it looks like this is a new unit. Manufacturing defects

Is any water at all coming out of the faucets or is it all air?

You will have run each faucet one at a time and let the air out. Would be easier if you hook up to city water with your hose. You will want to open the pressure valve on water heater tank till it flows out of it also. May have to do one for a while, then switch back. You will know when you are all good. Good luck

Check to see if you have your fill valve in the right position. Is it in the fill position or the service position. If it's in the fill position the pump will run all the time. That's what it does on mine anyway, just a thought. Jim

Blow it out with shore water first. Then see how onboard water works.

Pumps have a hard time picking up water for the first time unless all faucets are left open to allow the pump to push the air out and eventually suck up the water. At that point the pump will start pumping properly and the air will soon be pushed out.

Also the first time you will be filling the HW tank and that will take several minutes.

If that doesn't work then you can put it down to your first experience of both manufacturer and dealer failing to do the job they were paid for and hoping you will understand that they can't be expected to get everything in such a complex machine to work first time or second or tenth and that you will fix it for them.

BTW do you know for sure that the tank is full??

I agree with rvjimmy, check to make sure the tank fill valve is not in the fill position.

Note that the pump can run continuously for reasons other than air in the lines. The most common one is leaving the tank fill valve in the fill position, which basically just pumps water right back into the tank. Another is a leak or an open drain valve, either of which will prevent the pump from building enough pressure to reach the shutoff point. Still another is debris on the pump inlet screen, which prevents the pump from getting enough water to build up pressure quickly.

Where did you put fresh water in? Fresh water tank or hook hose up to water inlet(main hook up)? Usually if water pump continues to run with everything shut off it is leaking somewhere! If pump runs when you open a water valve you should eventually get water. When all water gets in lines (toilet, bathroom, kitchen, shower, water heater) you should get water out of both hot and cold sides. If you get air then the pump may not be primed and is not picking up the water. I would try to connect hose to rv and open faucet fartherest from supply as suggested above. You have a valve close to the hot water heater that should be close as it will only let the water bypass heater and not fill it up. You also have a valve that should be closed close to the water heater as water will just run out on the ground. It is a water drain line. Hope this helps. Someone with more experience hopefully will come along that has more ideas. hope you get it solved.

First, I'm surprised that the dealer did not fill the tank and do any leak-testing before you took delivery. That should have been a part of make-ready IMO. Since it is a new unit, can you take it back to the dealership and get them to help you determine the problem?

You might contact Fleetwood Customer Service to see if they have a procedure to follow for first-time water fill up. Good luck to you, and don't get discouraged.

If you have a city water fill, make sure it is off. Make sure you have at least 1/3 tank of water. And make sure any "winterizing vales" are closed or set to normal. Make sure the plug/anode rod is in the water heater. And make sure the low point drains are closed. Then open a faucet, to vent air while the pump picks up the water from the tank. You have to leave a open faucet till you get water into the system. When the pump picks up water from the tank you should hear the tone change. Once you get water out the 1'st one go around to every faucet & the toilet and bleed the air. If filling the water heater it will take some time to get water out the hot side.
