Water Tank Won't Fill

[Webfoot0807]

Have a weird problem on my 2016 3200BHT, hopefully someone can help:

While de-winterizing for the first time I tried filling the fresh water tank but after a minute the water came rushing back out like the tank was full. According to the gauge the tank is empty, and the pump doesn't prime so I don't believe that the gauge is wrong. I switched the inline valves at the water heater and the water pump, and all faucets work fine on city water.

Did I miss a valve or bypass somewhere?

This is a common problem. The first and most common problem with the gravity fed fresh water fills backing up is either a sag in the fill line and / or a kinked vent tube. So before anything check those two items. You may have to do a little disassembly to get to the hoses but it is more than likely the issue. Nothing you do will help if those hoses aren't in proper position. You can also check this item out to assist with filling.

If the undercarriage is sealed, do I disassemble it from the access panel?

The first thing I would do is remove the 3 screws holding the gravity fill inlet to the rig. Sometimes you can see in there to check hoses. Even better yet is if you can take any slack or kinks right from there by pulling on hoses and reattaching. Each rig is different as to where those hoses run and I am not sure with your unit model until you start looking.

I'll check it out, thanks

As usual ~~ found at 1/3 the price of Amazon. The last 3 items I ordered were found for less than A-zon Prime incl shipping.

I have had the same issue on my 262rgx Wildcat. On mine its a plugged vent line. I have found that by holding the filling hose in the filler tube so it somewhat seals i can force the air pressure in the tank as it fills to blow the vent line clear. It must have a low spot which fills with water. Once clear you can feel air escapeing out the vent as you fill

Can you follow your water lines from the fill spout to the tank? On ours it comes from the fill spout in beside the water heater and down and onto the top of the water tank. Our old one was totally accessible and a couple of ty-raps fixed our culprit - the vent had a droop in it and was lower than the fill line..

I have this problem with my Sunseeker 2860DS Model 2012. My solution is to blow out the vent tube with an air compressor at home or, on the way with a cheap 12V tire inflator. There must be a sack in the vent tube that fills up with water, if I overfill the tank and the next time filling, the problem shows up.

I can't access all of the lines because the undercarriage is sealed. Both fill inlets and the vent tube are on the same panel though, I am removing it tomorrow to check the vent tube

First try to blow the water out of the air vent with a small hose,,, then try to fill tank VERY SLOWLY !!! With some units it helps to have a short hose that will fit in to the fill tube,,, it still needs to be filled Very Slowly !!!

Also the screen on the air vent must be clean !!!

[Webfoot0807]

It was the vent screen, it had some clear film on it I had to scrub off. Works like a champ now though. Thank you for the help everyone!

Solved the problem by purchasing several feet of clear half inch tubing and a female hose adapter. I can feed the tubing into the tank fill connection directly into the tank. With hose adapter, I can attach the hose from the water supply. It only takes about 3feet of tubing so it is no big deal to carry with me.

Yes that works well,,, I use about 2 feet of garden hose with one end cut off !!!
We are filling below the crappy air vent !!! Still good to not try to fill to fast !!!
Just sit back and have a cold one while filling !!!
