Toilet shut off valve

[AbdRahim]

Anyone put a shut off valve on the back of their toilet? What size is the fitting that goes into the toilet? BayStar 3626.

Curious - why do you want/need a shutoff valve? You have one at the wet bay - turn off the pump or city water.

In case of a toilet valve leak, like the other gentleman described. That way I can continue to use water in the rest of the coach. This has been on my mind since the last coach and I never got to it.

If it were me...I would simply cut the PEX and install a ball valve inline. It's possible your water inlet is 1/2" ID (Easy to measure before you make a trip to the hardware store ?) and install using pipe clamps. Should be easy-peesy! (Until it's not!) Good luck my friend.

All pex plumbing has labels along it's length outlining, specifications and size amoug other things. It's written everywhere. I believe all of the plumbing is 1/2" in diameter. You can find a part with the label then you will know.

There is a healthy mix of 3/8 and 1/2.

I was going to guess 3/8 on that line.

 

[Old-RV'er]

Could be, but pipe is labeled, so no guess work here.

Not concerned about pipe.I was thinking of a valve with male thread on one side and female on the other. I thought I could just get something to screw into existing fittings.

Assuming, you can take it apart. The pipe coming into that "screw in" fitting has been crimped with a special tool. You can get one at HD, it was in the 70 range when I bought mine almost 6 years ago. They also sell the little fittings to crimp it with. Not sure how you are going to unscrew that fitting. Cannot see back of it with your picture. Have fun with this one.

To me you're asking for trouble such as a leak, flood, etc. so be very careful. The "easiest" option is like is done for our ice makers and other pex lines you may see running in the basement where they have inline shutoff valves. For the pex size you'll probably have to cut it and measure but you could measure the OD and probably be fine knowing that number to go to Lowes/HD and find the parts that match the OD which will give you the ID. I bought a pex crimp tool, the good (right) one is not cheap but good to have. The other option are hose clamps. Adding fittings to the end as you describe still may require you to cut and shorten the pex line which would require cutting off the pex clamp, cutting the tube length down, then reattaching the fittings on the end and using either a hose clamp or another pex clamp. If you've never used pex clamps you can watch YouTube videos on it, moral is you have to clamp it at the proper angle, i.e. not at any angle on the hose when crimping, it has to be aligned perfectly.

I would find a plastic male male inline valve. I would send your picture to Newmar parts as they know the coach and pex size. Tell them what you want to do and they may know the exact part to get. I'd get something like the ice maker shutoff valve that's in the basement pex line.

At Lowe's or Home Depot you can buy a Sharkbite valve with the configuration you need. Just cut the line with a knife {it is tough} or a tubing cutter {preferred} and slide the Sharkbite on. No special tools are needed. Now should the toilet flush valve fail, you can shut it off and still have the water system operational.

The valve below is similar to what I used on ours. Just cut 3/4 inch or so from the existing line and insert the valve. You line is shorter than ours so not sure it would fit. Could be possible below the floor as well.

Thanks folks. I am familiar with Sharkbite. I don’t have much room to work with and was hoping for a simple screw on solution, between the current fittings.

I have the same installation and adding a Sharkbite only adds about 1" in total line length. So cut out 1" of line and install the Sharkbite. All dimensions will then be the same. Adding a screw-on solution will take 3" or so and you'll have less area to work.

Oh, it is best to remove the toilet, cover the hole, and do the plumbing work. Much much more comfortable to work with an uncluttered and accessable area. The toilet is likely held in place by 2 bolts. It will go back the same way it came out.
