3-Way Thermostatic Mixing Valve DN15 Temperature Control Anti Scald

I’ve been using this thermostatic mixing valve for our outdoor dog bath, and it works great! It does a really good job of controlling the temperature and can easily provide water that is cooler or warmer as needed. My only complaint is that the temperature markings are in Celsius instead of Fahrenheit. It took a little getting used to, but it doesn’t bother me too much. Once you get familiar with the settings, it works really well. Overall, I’m very happy with it and it has been perfect for our outdoor dog bath.

Great replacement valve. No modifications to the connections needed. Easy to install. Works very well.

december 2025 Over time I ordered and used 5 of these and they perform well. No issues at all.

Wanted to chime in on the reviews - complaints aside, this is an excellent valve for the price. Do the threads leak? Yes - if you install fittings onto this mixing valve and wrap it with Teflon tape the way you normally would, chances are that it will leak. Two of the three connections on mine leaked. Is it insurmountable? No - wrap with Teflon tape a bit heavier (5-6 wraps total) toward the beginning (inlet/opening) of the threads, trim off excess that laps over the end (so you don't clog your screens/fittings, and try again. Not wanting to attempt a third install, I did the above and also added a bit of thread sealant to the female fittings. It's been functioning excellently for the past three weeks. Also, NOTE - I had to two-wrench tighten this significantly more than I would typical fittings. Bottom line, the next comparable mixing valve is over 3x the cost - play with your taping and/or sealant a bit and this will serve well. Update - 3 months later, still going strong, no leaks, this is a solid and responsive valve.

I use it on my bidet because I don’t have hot water close by. I first put on a portable instant water heater. Too hot for my liking so I installed this mixer and all is well.

I used this for bidet water. I put it in line with the toilet flush water in the basement, and it also prevents condensation on the flusher tank. The water temperature adjusts very quickly to the right temperature. it appears it uses hot water as long as it is colder than the set temperature, and then starts adding cold water immediately so I didn't feel any hot water coming. First of all, the issues people have with threads are pointless. You need to study on BSPP threads and I recommend this video: https://youtu.be/aXqGrWUkJ1s?t=3m27s . Basically, you need an adapter WITH A SPECIAL WASHER that SITS OUTSIDE the fitting. I purchased 3 Female BSPP to MNPT adapters that come with the special washers with amazing results: http://a.co/a0lulcj . What I could find was that this valve does not have a built-in check valve. I don't know if it provides an equivalent functionality, but I put check valves on both inputs just in case. These come with built in strainers on both inputs. One issue I realized was that I may need to open these once a year to clear out the debris and that mean undoing the plumbing work. I put two inline strainers on the input lines with easy cleanup: http://a.co/0SRiJKl , Use these at your own risk. I also put two shut off valves very close to the strainers. I will update this review with any issues I may see with this setup in the long run.

I purchased this valve and had it installed started to leak and the joints, leak got worse day after day. So I thought might just have been a bad assembly. Ordered another one and installed it. Same issue happening again. I have now spent 150 dollars in piping and materials and 2 days of time and these bales are no good. Do not purchase them

I have a dog wash system that accommodated hot and cold but very hard to control the temperature so I acquired this and split the water feed between the original faucet and now I have a dedicated temperature control for a dog washing.
