A modification I made to more easily fill my fresh water tank. I installed a 1/2" threaded 3 way ball valve in the area of my water pump. I connected the input to the valve to the outside hose connection. One of the output ports I connected back to the water pump, the other output port I connected to the old breather hose to the fresh water tank. I cut a hole in the bulkhead wall of my front storage box to access the valve handle. The old filler hose now acts as the breather hose and I can still fill the tank with that hose.With a hose connected to the RV, I reach the valve thru the storage box and turn to the fill position. It will fill my tank in 4-5 minutes (will depend on water pressure).I used PEX pipe with SS cinch rings for the connections(I own the tools and connectors). You could also SS 1'2" FPT faucet connectors.Trying to figure out how to post a picture.

I’m nervous about filling fresh water quickly and look forward to your pictures.

Lately I've been seeing quite a few posts about mods & different ways to fill the fresh water tanks, some, Like this one seem to be a lot of work, makes me wonder, do I have the only MH with a gravity fill port, remove the cap, stick the hose in the hole, turn the water on? I have a friend with what appears to be 2 city water connections, but one of them is to fill the tank.I thought all RV's came with a way to fill the tank. :h

My TT’s gravity fill works fine and I’m not in a hurry.

Our new '88 Mallard and new 2001 Itasca both had a gravity fill port. Out 2014 does not. I built one using 3/4" PVC pipe and a 1/4-20 stainless threaded rod.

My RV has a gravity fill port but when I stick a hose it it to fill it constantly burps and spews water back from around the hose. This mod eliminates all of that.

Think of your fresh water tank like a balloon. Dont want to crack and pop it. In colder weather make sure to fill as slow as you can. If you are filling up at a public spot dont feel rushed. Sounds like your original tank vent has either failed....or....you crank the fresh water input full blast and the tank cant vent fast enough. Thats how people balloon their fresh water tank to the point it will lift your floor up. Bend the metal mounts. All types of badness.

This might have come in handy in the first rig I rented which was a real PIA to fill .... in hindsight I suspect there was a kink/blockage in the air bleeder valve.
