Watts 206070 – Frequently Asked Questions
1) What connections does the Watts 0206070 mixing valve use, and can I thread it into copper?
All three ports on the Watts MMV 0206070 are 1/2 inch union solder: hot inlet, cold inlet, and outlet. You sweat it directly to 1/2 inch copper. There is no threaded option on this model, so if your rough-in is NPT you need adapters or a threaded version of the valve instead. The unions let you break the valve out for service without cutting pipe.
2) What temperature can I set the Watts 0206070 to, and what does it come set at?
Adjustable from 80 to 120 degrees F, and it leaves the factory set at 105 degrees F. Outlet accuracy is plus or minus 3 degrees F. That range covers domestic hot water tempering at a fixture or a small distribution branch, but it will not deliver above 120, so it is not the valve for a dish machine or a high temperature process line.
3) What water heater temperature do I need feeding this Watts thermostatic mixing valve?
Hot inlet needs to be between 120 and 180 degrees F, and the valve also requires at least 5 degrees F of difference between the hot supply and your setpoint. So a tank running at 110 will not let you hold 120 out. Cold inlet is rated 39 to 85 degrees F. Store hot at 140 and temper down and you are well inside the window.
4) How many fixtures will a 1/2 inch Watts 0206070 mixing valve handle?
Flow range is 0.5 to 20 GPM, with 20 GPM at 125 PSI. The low end matters as much as the high end: it holds temperature down to half a gallon per minute, so a single lav will not make it hunt. On the top end 20 GPM is enough for a small multi-fixture group off one heater.
5) What pressure does this Watts MMV valve need to work correctly?
Minimum 30 PSI static, and hot and cold pressures must stay within 25 percent of each other. Maximum working pressure is 150 PSI. If you are on a well or a pumped system where hot and cold pressures swing apart, correct that first or the outlet temperature will drift.
6) Does the Watts 0206070 shut off if the cold water supply fails?
There is no cold water bypass on this valve, which is the safe behavior: lose cold and it does not pass unmixed hot straight through to the fixture. Property managers standardizing scald protection across units generally want that.
7) Is the Watts 0206070 mixing valve body bronze, and where is it made?
Bronze body in a rough bronze finish, made in the United States. The bronze body is what suits it to potable domestic hot water service rather than a plated decorative application, and it is a common spec call on institutional and government jobs with domestic sourcing requirements.
8) Is this Watts mixing valve a smart or connected device?
No. The MMV 0206070 is a purely mechanical thermostatic valve with a manual adjustment from 80 to 120 degrees F. No wifi, no controller, no power required. If you need remote temperature monitoring you are looking at a different product line.
