Water tank.... overflow

When I fill mine, I stop when it starts raining under the coach.... :W

Can't over fill it. There is an overflow tube, water will start pouring out that tube. That's the only way to know it's full!

So bottom line it will spit water back at you but make sure your standing there when it does so you can shut off the water.

I agree with the second quote here, and I absolutely disagree with the first quote.

First buy one of these fresh water tank filler tubes, you won't regret it because you can flip the shutoff switch when it does hit full so you don't get wet! :W AND the filler tube fits down into the hole, a garden hose doesn't.

I am fortunate I just open the bay door for the fresh tank and I can watch it fill. But I still always use the filler tube.

Your question has been asked before. Try to do a search on water overflow

Welcome to the forum.

You could have answered his question in less keystrokes than your non-answer non-welcoming response.

You can't see your fresh water tank when filling? Wow, the things I take for granted. I have a sliding access door that allows me to see the entire end of the fresh water tanks and also access the 12v water pump and associated fittings and sensors on the fresh water tank.

On our HTT we used to own, it had a gravity fill. When the tank got close to full, water would spit back out the gravity fill. Our motorhome has a single water connection for both filling the tank as well as using City Water. We move a few levers to switch functions. With our current setup, when the tank gets filled, additional water exits through an overflow valve that just spills water onto the ground. When water starts hitting the ground, I know the tank is full.

Picking up our first TT on Friday a Dutchman colman 31'. Our first trip the site does not have water hook up but does have stations through out the state park. Probably a stupid question but when fill the tanks how do u know they are full without over filling them causing a problem.thanks again sorry if it's a silly question

If filling your H20 tanks for the first time, put your wide open water hose in the fill spout, turn H20 on. Time with your watch how long it takes to see water spurting out. Turn the H20 off. Now you have an approx. time measurement it takes to fill your tank when empty. You can also use your "idiot" panel light gauge to measure but all gauges are rarely spot on accurate. Overfilling your H20 tank will not cause any damage to my knowledge.

Even if you didnt have an overflow/air flow tube for some weird reason, it would just spit water back out the entrance

Unless it's a threaded fill.

I will add that it can be very easy to overfill and do damage if your not monitoring the hose as it fills. On my last three trailers the hose would stay in the fill tube without being held. The overflow is much smaller than the gravity fill so if you have the hose cranked up once it gets full it can pressurize the tank and bend or break the support brackets. I found out the hard way. I have seen it actually lift up the floor in a trailer and heard about a motor home that ruined his floor inside and burst the tank when he forgot and left the hose going for too long.

First, when your toilet tank is getting pretty full, you will start noticing the stink inside, since it's past the vent pipe to the roof. You don't want that smell seeping in for long. Also, at that point, the toilet will start to "burp". That is, when you flush, a bubble will come up and burst. Since the level inside is past the vent pipe, the air inside the tank has to come out when you flush and put more "stuff" in. Drain immediately if that's the case since there probably isn't much more room in there for more than a couple of more trips to the bathroom.

Second is your grey tank. Some are built differently, but if your grey tank is an isolated tank with no overflow protection to the black (toilet) tank, when it gets full, the water will start to accumulate at the bottom of your tub, since it's lower than your sinks. That will be time to drain. If there is some kind of overflow protection (yes, it does exist, as disgusting as it sounds) to your black and you fill it up (essentially BOTH will be filled), that water at the bottom of your tub could and will be a mix of both grey and black tank water. UGH.

Overfilling your water tank isn't much of an issue. Should be overflow protection, but even if not, no damage will occur since it'll be like overfilling your gas tank - it'll spit out at you.
