Price Pfister Parisa Shower Anti-scald valve fails to scald position

My California code, i had to install an anti-scald valve in my stand-alone shower. I chose the Price Pfister Parisa single handled faucet that has a plastic mixer valve in the unit behind the handle assembly. There are no works or it doesn't. It is a thermostatic type mixer. My problem is that it worked fine for 3 yrs and then suddenly failed to the full scald position. Playing around with the temp selection via the handle sometimes worked, but the problem deteriorated to point all i could get was full cold with handle barely on or full scald, handle at any other position. When i removed the mixer for troubleshooting i notices a tiny rubber o-ring on the hot side had broken. The cold side o-ring was still intact. The o-rings are really not a good design IMO. Anyway PP sent me a new one under warranty and problem was fixed for two yrs. Last week, the valve failed to scald again and my wife and i are using the guest shower until PP can be contacted again. Is anyone else having problems with these Federally mandated anti-scald valves??? My biggest problem is the valves are failing to the scald position....what good is that???
