Replaced our shower faucet with a MISSMIN 4 inch Thermostatic RV Shower Faucet Valve from Amazon.
A simple job to replace except the that the facuet bezel also needs to be replace since the existing one has 3 holes, Amazon also has a 2 hole one in white from Rec Pro.

I've only tested and it does a nice job of flow control, mixing/controling the temperature, getting ready for a 3 week week trip so that will serve as a better test of the overall fuction.

Appears to have a stronger flow also out of the sprayer head.
Real simple operation:
left valve controls overall flow and the right valve control temperature.

Our shower head also has a valve so we can shut off there to conserve water and maximize the hot water usage.

There are strainers in the valve assemby which are easily accesable from the back side of the facuet, shut off water and loosen the 2 nuts on the rear of the faucet to access and clean if necessary.

The thermostatic valve is also servicable if it needs cleaning from any scale buildup. That is detailed in the instructions sheet.
I'll provide some more feedback on our experience.

Any photos? We are not happy with our shower valves because they are lever style. Which I like but my wife always bumps them and turns the water on. We put our laundry hamper in the shower when not showering so it gets soggy when she does this.

Have a 3 week trip coming up so I will post an update on how it performs overall.

Out on our trip for about a week now using the new the new Thermosatic Facuet valve. Really works great for us. More or less have the temperture position set and we just need to open the flow valve and in a matter of a couple seconds it is controlling the temperature.

Really like how it functions.

We have no vested intrest in this product and would recommend it.

If possible, can you post the link to the faucet that you bought on Amazon? That would save several of us from having to do the search thing.....thanks in advance.

I read a review on another site by someone who had installed one of these in their motorhome. They said it clogged up and quit working very quickly due to hard water in the RV park. Please get back to us after you've used it for a while (and what the water conditions were). I would be very interested in this if it didn't require frequent cleaning out - we're in a place with pretty hard water.

Thanks,

Rob

Rob,
We have been out for about 4 weeks with out any problems, For the most part the water has been mostly soft.
We have been in Alabama (Desoto State Park & Foley), Tennessee (Gatlinburg), Northern Georgia, Unico State Park, & Mississippi, Buccaneer State Park).
Works prefectly, rarely have to move the temperature position and helps conserve the hot water most all the time, no real way of telling but we haven't run out of hot water during use.
 
Thanks for the update....and let us know if anything changes with your satisfaction of it.
 
Thanks for sharing this, I need to add it to my list. We waste too much water when boondocking trying to get the current faucet to the right temperature. It's the dual knob version. It's fine when hooked up to water but when trying to conserve it's a pain.
 
I should have asked earlier, what was the installation for the water lines? Did the existing water lines fitting screw onto the faucet or did you have a cut the line and put different fittings on?

Not trying to distract anyone from the original topic but thought this would be a good plug regarding boondocking "...wasting water..." and at the same time getting the water to the right temp if boondocking.

My suggestion is to run the water into a bucket, pitcher, whatever while waiting for the hot water and then use that water for flushing the toilet(s). This is hardly a new (or original) idea. But with so many new folks boondocking I thought it might be worth a mention.

Carry on......
 
I know this is old, but how did you attach the faucet to the bezel? If I use the nuts from the old tap then there isn't enough threads sticking out to allow the water connection to seal. How did you solve that. Thanks.

@o3griz -

Who are you asking? Here are a few forum tips:

1) If you use "Reply With Quote" (to the right of "Reply") as I have here, folks will know to whom you are responding and that person will get a notification.

2) You can also tag folks using the "@" symbol and their user name (as I have done yours) - they'll also get a notification that way.

I replaced the bezel with a new one that just had 2 holes there wasn't a problem. There are 2 adapters screwed into the rear of the faucet and 2 lock nuts used to sandwich it all together. The hoses screwed in to the rear of the adapters. Hope this helps

Question. What type of lines run to the faucet? Pex or vinyl? Any issues with line length...enough to work with or did you need to add line to work?

Thanks

They are PEX, looking back and since I had problems with most of the rest of them I wish I would have changed those plastic type ones out. Probably put this on the To Do LIST.

I’ve read about the cold water pushing into the hot water line when the shower is shut off then you get burst of cold water when you turn it on.

Does this product prevent that or is the Camco back flow device still required?

Thank you
