Upon arrival turned main water off, cut out and replaced PRV and set pressure. After PRV was installed installed new Novo water softener, installing ball valve on inlet and outlet side, outlet side was ran directly into polyphosphate filter, then looped back into system. Tested for leaks by turning main water back on me airing out lines, after re-pressurizing the system ran softener through regeneration cycle and went over softener details. All good no leaks and all fixtures are working properly.
