3-Way Thermostatic Mixing Valve, DN15 Temperature Control Bathroom Faucet and Shower Water Mixer Valve G1/2 NPS Male Connections,Chrome…

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.

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.

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 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.

Amazon should STOP selling this mixing valve in the USA. This is a well-made and cost-effective mixing valve. It would be a five-star product if they included three adapters from IPS to NPT with the valve. The valve has male ½" IPS (Iron Pipe Straight) / NPS (National Pipe Straight) threads on the connections. The mating fitting (if it could be located) also has straight internal female threads, with an internal washer that compresses against the face of the threaded connection, like on a garden hose, to seal the connection. The mating fitting was impossible for me to locate. These were not found on Amazon, in the big chain brick and mortar building supply stores or in any of the local professional full-line local plumbing stores. The US uses NPT (National Pipe Taper) threads, where the threads have a 1.7899° taper. Those NPT thread joints are sealed by application of a sealing material, like Teflon tape or pipe dope to the male threads, prior to tightening the fitting. When a NPS fitting is mated to an NPT fitting, there will be about one thread of surface-to-surface connection, unlike NPT to NPT that have many contacting threads. There is NO WAY I was going to depend on mis-matched parts to maintain a leak-free connection 24/7/365. When this connection silently fails, causing undetected damage, the insurance company would deny the claim, pointing to that incompatibility.

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.

Worth the money. Solved the condensation problem on the toilet tank. Dost waste your money on the insulation kits, they don’t work.
