Having an issue with the Bradley sinks constantly tripping on high pressure. Originally when installed, the city water pressure exceeded 85 psi and the sinks tripped frequently. Subsequently a PRV was added to reduce the city pres. to 65 psi.
Sinks however are still tripping on high pres.
Could the pres. switch have been damaged with the frequent trips and is now useless?
BTW - there is no mention of a high pres. cut out in the Bradley manual.
Any help would be appreciated.
Tks

65 PSI is borderline high. reduce the pressure to 45 PSI.

Normal city pres. around here is between 50 and 70. Never had issues before with these sinks at these pressures. If the are "rated" 20 to 80 psi operation....65 is 15 psi below rating and should be more than ok.
I'm more concerned about the durability of the high limit - will it wear out with constant trips?

Bradley Corp of Wisconsin, has been around for decades, making several different models of lavatories and sinks. Which model are you refering to? Concrete, Metal or Fiberglass? Are they using pressure balanced cartridges or solenoid operators. Do you have a model number?

Express....MG3.
With Battery IR operation/mixing valve and solenoid I believe.
There is no mention of the pres. high limit in the Manual - any idea why not?

Solenoid Valves have plungers that allow water to by-pass when they open and when the energy is removed those same plungers, stop the waters from flowing.
I'm guessing, without seeing, that your water may have some debris that is affecting the plunger from seating, regardless of the pressure.
Some of that debris could be plumber's putty or minerals. The solenoid or solenoids must be removed, and cleaned. Inspection should be made to make sure they "seat" properly when power/energy is removed.
Also depending on the age of your Express Lav, use only Bradley Original Repair Parts.
