      A:  It keeps temperature and pressure level under control for your tankless water heater.

        A:  PR valve is 2 valves “1 for hot and 1 for the cold” is used to isolate the tankless hot water heater either for repair or mantainace ,,, the tank less hot water heaters will need cleaned with vinegar mixed in water regularly if they are heavily used,, what happens is the heating elements will boil the calcium and other elements that are in all water out during heating and it will collect in the heating chambers,,,causing the water flow to reduce, not heating properly and eventually burning out the element itself,,, see video on you tube for proper matainace

        JUNK! Well designed but poor quality
        I bought this about 2 years ago and didn't know why my stainless steel hose was totally molding. I didn't see any water or leaks anywhere. So I decided to change the hose out. Well when I put the new one on, I saw the tiniest leak from the welds. VERY disappointing. I had to get a whole new unit (different brand) and re-do everything! I spent probably close to $200 and running back and forth to the store to keep getting more and more hardware to fix this! I do like how compact it is though.
