Answer This Question

I am not familiar with that Navien's inlet and outlet connections but most tankless water heaters use 3/4" MIP inlet and outlet connections. I would look up that specific heater and make sure it has the 3/4" MIP inlet and outlet before purchasing. Thanks

        My problem is low household water pressure and have a Bosch tankless w/h that works ok on first floor use, but not for shower on second floor. I also read about the hot water tank booster, which one could work for this situation. Thank you for your help.

        Answer This Question

        Thank you NewSanDiegan for the question. BrassCraft tankless water heater service valves are used to shut off water flow to and from the appliance. In addition, the valves have several features that ease the task of appliance maintenance. Unfortunately, tankless service valves are not intended to regulate the pressure of the water distribution system. Hope this helps. If you have further questions please do not hesitate to contact one of our Product Experts toll-free at 877-272-7755. Have a great day.

          I am clueless when it comes to valves - what ever my plumber needed, this worked like a charm. Like that it was solid brass.

          Seized Up in Under 4 Months
          Installed this kit in February and the hot water supply valve is already seized. Pathetic.

            Very bad product. Will never recommend.
            Threads are so wide that every joint leaked, had to do few times with tons of teflon tape and great white compound, pressure relief valve was also leaking and never stopped draining the tank.Very bad product. Will never recommend.

              Installation was easy, they look like they might do the job. Won't know until that time comes in a few months.

              Bought as a back-up set for when valve change out is needed - valves last about seven years due to well water low pH that is corrosive to metal fittings.
