Adding a gravity water fill

Rossi6998 · 12-22-2013, 07:09 PM

Hello,

I have a 2013 Sunstar 26HE. I love the motorhome, but it does not have a gravity water fill. Does anyone know if it is possible to add one? Looking at my water tank, I would think someone would have a way to add some type of threaded connection that would allow me to something to fill the water tank while dry camping.

I do have an external 12v water pump to fill through the city water connection, but I would rather have a gravity fill. Any ideas or suggestions would be appreciated.

If you have the usual antifreeze suction hose, you can use it by using an adapter to female garden hose. Set city water valve to tank fill and turn on pump and turn antifreeze valve.

If you have easy access to the water tank and you can cut in a gravity water fill door

According to Winnebago Support, this will not work on my motorhome. Having said that, I have not tried this and probably should just to make sure.

You can test by turning city valve to tank fill, then turn on pump. If all faucets are closed and pump runs, then you should be able to use antifreeze hose if you have it.

If you have access to the top part of the tank to add a fitting for another fill source, the route is clear to an outside location to add the proper fill door and hardware and you have no problem cutting the whole in your rig, I see no problem.

I can only say what I did to my '89. Was able to see the tank when I removed the cushion from the dinette. Shopped a PVC fitting that would work cut a hole into the tank and glued it in. Hardest part was getting the nerve up to cut the hole. Had to bring a hose inside to fill, but primarily used a jerry can.

If you are meticulas and can get alligned to bore a clean hole near the top of the tank you could get by with a slip seal setup through the side of the tank.

I pondered the same as you. I decided to go with a pump. Got it from
harbor freight and it works slick. No prime. I pack an extra 30 gal when we dry camp out in the desert.

I probably picked up the same pump from Harbor Freight. Still want to look into a gravity fill solution.

Thanks

To me a 50 gallon water bag in the back of my SUV and a pump would be preferable to multiple trips with a bunch of 5 gallon jerry cans manually held up to a gravity fill. I have a gravity fill on my rig and the gravity fill is used with a hose as I could not imagine hefting 15 to 20 jerry cans to fill-err-up

I have the water bag and Harbor Freight pump and use the hose from the pump in the gravity feed.

Just wanted to let others know that this worked perfectly for me. Just stuck the anti-freeze hose directly into a 5 gal water can and pumped the contents into my water tank. Took about 1 min. Thanks for the post.
