In response to Re: Pressure balance with Circulating Pump.
: Hello,
: My question is a slight bit unusual and technical(not really). The questions is in regards to a remodel project in a 100 room motel. The property is about 15 years old. What I would like to know is:

: Will a recirculating pump maintain constant pressure? This pump is only on the hot water side; currently

: Do I need AntiScald Valves if I have two recirculating pumps; one for the hot line and the other for the cold line.?

: How do I know if the current valve mixer is anti-scald or not.?

: Thanks in advance

-No, it will only circulate the water.
-Yes, new installations are required to be pressure balanced, existing units can remain.
-Disassemble the unit and inspect the cartridge or bring it to a plumbing supply to be indentified.
Good Luck. e-plumber
