Neat, quick & temporary waste valve repair.

I've had a twist on valve since the first time I dumped and got a poop shower. Should be standard equipment.

B.O.

I went this route on my previous trailer and was very happy with the results. I had the usually problem old valves can have of leaking. Spending the money for the twist on valve was money well spent so I could tackle replacing the leaky one on my time. That never happened and when we traded it, I kept the twist on for my new trailer. I like the fact that I have a second safety valve for when I do something stupid.

Not necessarily true. Time it takes to replace the valve depends a lot on it's location, how rigidly it is lock into place by other drain lines, etc. and whether or not the trailer has an enclosed underbelly. :S

Dutch 12078 has it right! I do the same thing for the back-flush process. I use a "Flush King" style. Same as the OP referenced, except it has a clear section you can see through.

About a "simple" 10 minute replacement if the camper valve goes bad??? That's not true for every camper. I'm on my 3rd camper and each camper has had the slide valve hard plumbed into the black PVC lines. The only way to get them out is the cut the black PVC drain pipe and replace, there's no flexibility as both tanks flow to the same point. In my current camper, it would be even more difficult (much longer than 10 minutes), as I'd have to remove the under cover first. That in itself would probably take MUCH longer than a simple 10 minutes.

If you do go this route something to be careful is using a washing machine. Not all washers send waste water into a tank. Some send it straight down the waste line and out. If you have a valve at the end which is shut, then you'll overflow at the washer pipe.

Yes, some valves are very expensive and hard to swap out. Thetford is one of them and may even be glued on.

Well maybe on your unit!

My unit the Grey and Black thank face each other and the valves are right at the tank, with a Y between them. Tried once to loosen and move the tanks just a bit, no luck. The twist on is a good solution for now.

I have the Valterra twist-on valve semi-permanently installed on the waste outlet. When dumping, I open the third valve and the black tank valves first, then close the third valve and open the grey tank valve to back flush the black tank with grey water before draining everything. The third valve also makes it easy to gain extra grey tank capacity by letting it equalize with the black tank if necessary.

I sometimes put grey water into my black tank when boondocking. They are on the same level and the two valves are close together but that leaves about a quart of stuff between the valves. By using a $6 end cap with a hose bib and a $5 hose valve I can drain the quart of stuff into the sewer hose before taking the end cap off.

Dennis, if your valves are like mine it's nearly impossible to get the old valve out as everything is that ridged. I had to cut a 1/2" section out of the smaller grey pipe and put it back together with a rubber hose.




Sometimes a hose goes on it instead.:W
