Toilet Water Valve Leak

I am filling up my trailer with water the other day, and my first clue something was weird was when my water pump kept going. Didn't think much of it, shut it off and moved my water hose over from the holding tank to the fresh water connection so I could prime all my faucets. I go inside and notice I don't have a lot of water pressure. As I am stepping outside, i see water dripping underneath the trailer towards the front. I go in the bathroom and the toilet water valve is flowing pretty good. I get the water stopped outside and start to sop up the water. This will be the second one of these I will have replaced. Is this a common issue or am I the only one with this issue and maybe not winterizing the trailer correctly? I follow the owners manual for winterizing, it doesn't show anything specific to the toilet. I use compressed air (about 35 psi) and run it through the system until no water is coming from any faucet. Then I put some antifreeze in all the drains. We triple check every faucet too. The valve is a Sealand 385314349. Any help is appreciated, I am tired of fixing this piece.

    When using air pressure you need to step on the pedal and trigger the sprayer that's attached to the same valve until they both run dry. My manual doesn’t mention anything about this procedure either


    I think you are right. I am going to assume it was bad winterizing on my part. I will step on the toilet pedal to push air thru the valve next time I winterize. Thank to all.

    I have had the same freeze problem with my unit. When you simply drain the valve the water remains in there (because of the twisted pathway) and then it freezes. If you add anti-freeze it doesn’t get to this valve because of the same twisted pathway.

    When using air pressure you need to step on the pedal and trigger the sprayer that's attached to the same valve until they both run dry. My manual doesn’t mention anything about this procedure either.

    I haven’t had a problem in several years now that I blow out the pedal and spray line.

    I had this problem a couple times over the winter in our RV during sub zero nights. I narrowed it down to the water lines freezing (or partially freezing) in the RV, which caused the water pressure to drop to a very low psi. For whatever reason, when the water pressure is extremely low, the valve on the toilet isn't forced shut, and the low pressure water is allowed to run past the valve, filling the bowl and eventually running into the bathroom.

    I did 2 things. Installed a manual shutoff valve on the pex line running to the toilet. I also installed a water leak alarm around the base of the toilet which goes off if the toilet bowl floods.

    The RVDreams thread has some good suggestions too. Electric switch, or the electric flush toilet...

    AZ most of the plumbing now is all plastic, plastic is OK, we use Pex in home building these days, there is however a wide range of fittings and quality, some of the RV stuff I have seen has been pretty cheap, fittings can fail, more often than not it happens during the original install, (over tighten, bend aggressively, etc....) it holds for awhile but after traveling and use it ultimately fails. Don't get me wrong it could have frozen due to remaining water, but you did use a compressor, and hopefully opened your low point drain and bypassed your water heater. If you must change the whole fitting use a higher quality one......good luck.

    It looks as the black, screw on "cap" on the bottom side is cracked, thus causing the leak when the water is pressurized. Since the cap is on the bottom, I am thinking the water stays there when I winterize the trailer, and this water later on freezes and cracks the cap. If I could find caps that would help, but its the entire valve or nothing at all. I guess I was wondering if anyone else had this issue, or if it is just me. Wondering if it is my winterizing (or lack there of) or terrible parts.

    AZ, these toilets often have these running issues nothing to do with your winterizing, go to RVDREAMS, THERE is a recent thread call Potty Talk, we discuss a pretty easy fix , it requires a 12 volt 1/2" water valve and switch, if you have any questions ask away.
