We just picked up our FFX 189FBS. The water pressure seems low and sputters as if air is getting in. Here's what I did to try to figure out what is going on:
--Turned the bypass valve for the winterization tube (clear plastic tube used to put in anti-freeze) over to the bypass setting briefly to see how that affects the pressure. As expected, water to the pump stops because it is now trying to get supply from the little tube.
--Switched it back over and let it run with water to get air out of system.
--Water pressure still low and sputtery.
--While water and pump running, put thumb over end of winterization tube. This caused the water pressure to improve greatly and stop sputtering. That tells me the little bypass valve must be faulty(not fully closing off).
--So, is it easy to just replace this little valve, or since the camper is brand new, should I have the service dept. do it?
--Water pump seemed to act as if water tank was getting empty-even with the sputtering problem listed above-but the tank fill indicator showed 2/3rds to 1/2 full.
--Looking at the water "basket" (clear cap on inlet line with a strainer in it), it would fill up almost all the way, but then drain back to be empty. When the tank is full, that basket fills up and the pump stops, having reached 40 psi.
--Is this an issue of where the tube is sitting in the fresh water tank, and if so, is that an easy fix?
New to all this, I need help!!
