## Description

Review: Works Well - Incorrect product description. Threads are straight (NPS), not tapered (NPT). Product leaks when connected to an NPT fitting. UPDATE: Had another go and cranked the 1/2 fittings on for all I was worth--no leaks. Device works perfectly for my application, prevent toilet sweating. Like that the temperature can be set down to ~68 F, some others cannot go that low.
Review: NPT unless you need NPS - NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight. Don't buy the NPS Thermostatic Mixing Valve unless you need straight threads, If you need NPT tapered no washer needed only thread seal buy the valve with NPT and no need to use the leaking fittings to change from NPS to NPT as almost all of the one star reviews did. Also a one star pointed out no directions come with valve for installation, the C on valve is for Cold water the H is for Hot water and the arrow is for warm mixed water out to fixture, and the red button lets you go over 100 degree water supply to fixture. The pointer is to set water temperature by turning the valve to the temperature you want. I put NPT to PEX fittings using tape on the NPT turned on the hot and cold water no drips worked great. set valve to 86 degrees, has a full flow and works great. I never tested to see if cold water fails if valve shuts down and I don't know if it fails to cold so I would not use it for anyone with any impairment that may scald them unless I checked that out first?

## Questions & Answers

**Q: is this lead free?**
A: yes

**Q: does this have internal check valves?**
A: I don't understand your question?. but I do use it to regulate the temperature of the water to my toilet tank. and it does a good job.

**Q: Does the check valve require equal pressure from both hot and cold water?**
A: Doesn't seem like it to me.  I have a lot more hot pressure than cold due to a big calcite bed.  Temp has always been dead on.  Hasn't failed me yet and since ours is connected to a bidet sprayer we'd know instantly if there were temp variations.

**Q: gallons per minute?**
A: That depends on water pressure, among other factors.
