        Noticed today that my fresh water tank has about 3″ of water in it, up to about 1 ” above the drain.
        Decided to drain it so turned the spigot and even open the low point drains and nothing happened.
        How do I drain the tank, I don’t use it except when travelling and we are now parked for the winter in one spot.

        I think with those connections, you may have to pull the valves, not turn them.

        X2 Valve is push/pull type not a turn to open.

        Terry,

        The tank drain is on the outside bottom of the utility closet (where your fresh water hose and can tv connections are). It is a “pull to open” valve. Draining that is the best you can do, but it will still leave a bit of water in the tank. To reduce the frequency of bleaching the tank, I try to run some chlorinated water into and out of the tank routinely.

        Terry,

        Before pulling on that “T” handle, you should find a small clip just below at the bottom of the valve. It’s like a “U” with indented sides to hold it in place. Remove that clip (careful as it’s small and may hide if you drop it), then pull up on the “T”.

        Hey Y’all
        There was no clip below the spigot so I gave the valve a hearty pull. It came away in my hand, no problem in that it appears I can simply push it back in.
        Mystery though as I didn’t get the tank to drain other than about 1/2 a cup. The water level is still about 1″ above where the drain goes into the tank.
        While I’m not using the tank at present, I will be in mid April when we head back home at the end of our winter stay.
        I’m concerned that when I fill up my tank that the water presently there will be mixed with fresh water and may affect the overall quality of the water.
        Any more suggestions are appreciated.
        Thanks in advance
        Terry

        Terry,

        I’ve pulled out “T” handle out also. It’ll pop back in. You could fashion a clamp or tywrap the T handle in place for travel security. Assuming it’s been a while since it’s been drained, try to run a flexible wire or plastic “device” and see if there’s a clog of some kind. (Maybe a long Tywrap?)

        Ours has what appears to be a permanent crimp style clamp that could be easily replaced with a hose clamp if you had to take more drastic measures. The tank shouldn’t be air locked so I’m guessing a clog.

        Thanks, good idea, I’ll give it a go and see if I can get it drained. Don’t want unsanitary water mixed in my whiskey.

        Two or three teaspoons per two fingers max. Even better is a good fresh store bought ice cube till ya get it all flushed out.

        Make sure you perform a good sanitization before you use that tank for other than flushing. How long’s it been standing in there, if ya know?

        Terry, assuming you don’t have a clog, maybe you could use Bigfoot to raise the door side, effectively tilting the water tank so the water can drain out.

        You could also run the water pump, but don’t let it run dry.

        We dry camp quite a bit and use the water tank often. The first few times we used I would drain it after each use to prevent any problems. It would drain but would stop with about 2 or 3″ left in the tank. Once the pressure reduced the flow would stop. Figured I had something partially clogging the hole. I used air from my compressor and blew air (not too aggressively) up the drain tube. Problem solved. I am sure the debris that created the clog is still in the tank and my eventually end up stopping the flow again. I’ll blow it out again if it does.

        Could just be plastic shavings from construction. Glad you got it licked!

        I have the same issue with my fresh water tank. I have used compressed air to blow the drain line back into the tank and it seems to work for a while then stops flowing again. So I also figure I have debris in the tank causing the problem. Any suggestions to open the tank short of drilling a large hole in the bottom corner and using a plastic epoxy to plug the hole? If I remove the tank from the camper is there a access panel anywhere on the tank? Should I just cut out the drain nipple and glue it back in after cleaning? Searching for suggestions.

        Greg,

        The forward black wall is very easy to remove.

        Still not having any luck, tried the wire approach, NG, don’t have big foot so don’t want to put too much weight on electric jacks. Guess I’ll try the compressed air and if it doesn’t work then the wall will have to come out.

        I got tired of leaving that 1″ of water in the tank so I took an extreme measure. I removed the basement side wall and placed a 2×4 under the passenger side of the water tank to effectively tilt the tank toward the drain. I then placed a section of plywood under the rest of the tank to act as a supporting floor and wedged progressive smaller boards under the plywood for support. I know I lost some capacity when the tank is full, but I like not carrying that extra estimated 5 gallons of water in my not so empty tank which is 98% of my travel.
        I did end up cutting off the drain tube just in front of the drain T valve and found it full of plastic shavings from the tank. After cleaning, I was able to put the shorter tube back on the nipple and secure with a small hose clamp.
