Help understanding this plumbing setup

[toney_c]

Hi, we are redoing the floor and vanity in our bathroom. I'm not sure I understand this setup for the plumbing at the sinks. It's a mixing valve, but it doesn't appear to do any good for the sink it is attached to. It seems to be on the second to last fixture in the house based on having some freezing in the past that only affected the sinks and not the shower or tub. I can't tell where the "mixed" line actually goes. As you can see it made for a fun removal of the existing vanity and will be fun to work around for the new one as well. Just trying to understand the purpose since it is very in the way.

It's a thermostatic tempering valve. Some Municipalities require them going to a shower valve's hot side it the valve does not have a scald guard internally. This keeps anyone using a shower from getting burned when someone else flushes the toilet.

A Tempering valve is NOT considered an anti scald device . The majority of the law suits I am involved in are scalding as plumbers installed a Holby* tempering valve as an anti scald device


*Holby is one of the best tempering valves available

• Anti-scald shower bodies fall under plumbing codes and standards for shower and tub/shower valves.
• They must conform to the ASSE 1016/ASME A112.1016/CSA B125.16 standard.
• These standards mandate a maximum temperature setting of 120°F (49°C) to prevent scalding.

I know a bidet can have a maximum of 110 degree water going to it. Was there a bidet in this bathroom or nearby?
