Common Questions

Can I install this at a lavatory or sink - is it ASSE 1070 listed?

Yes. It is listed to ASSE 1070, the point-of-use scald-protection standard, so it is legal to install serving a lavatory, sink or similar fixture. Its outlet adjusts from 95°F to 115°F.

Does the hot and cold supply pressure matter?

Yes - the maximum allowed pressure differential between the hot and cold inlets is 15 psi. A bigger imbalance than that is a real install-failure mode: the valve cannot hold its set temperature if one side is starved relative to the other.

Does it have integral checks?

Yes. Check valves and strainer screens are built into the hot and cold inlets to stop cross-flow between the supplies and keep debris off the thermostat.

What is the hottest water this can accept on the hot side?

Up to 195°F. The valve blends it down to the safe outlet range regardless of how hot the supply runs, within its rated pressure and flow.
