Another LHC modification is the shut-off valve. It’s cheap insurance against a failed toilet flush valve. If the valve fails, water will continuously run into the toilet which can result in a flooded camper. With a quick twist of the knob, the water is cut off to the toilet.

The only tool required for the job is a plastic tubing cutter. Remember to turn off the water supply! Before cutting, hold down on the flush pedal to make sure there’s no water pressure. Even though our Casita hadn’t been hooked up to water for weeks, there was enough pressure in the line to give me a shower surprise when I cut the hose!
Cut out a 1 inch section, push the black fittings into the hose ends, then slide the ends into the shut off valve. Push HARD to make sure the hoses are fully seated. That’s it! Turn on the water and check for leaks.

Hi Greg- I installed the toilet valve yesterday and all went well…pressure tested and no leaks. However, I notice that when turning the valve on or off- there is a slight little pulse on the black insert end of the lines…it kind of locks in as water pressure is applied… Is that normal and to be expected? I just want to make sure that’s how this type of valve works.
Thanks for putting all the great info/mods and accessories out there for us Casita owners. Cheers-
Yes that’s normal.
Thank you! Peace of mind is priceless.
