Pride Plumbing was called out for a water leak at a Rinnai R85 tankless water heater. Our inspection found a leak on a water supply line union. We cut out and replaced the union and tested for leaks with no further issues. We provided cost estimates to 1) perform a descaling service on the existing water heater; and 2) replace the unit with a new Navien 240A tankless model with a NAVICIRC recirculation pump (this would include: a) removing and disposing of the old water heater along with its electrical wiring, venting, and gas and water supply lines; b) installing the new tankless unit along with its service valves, PEX and stainless steel water lines to the unit's water connections, copper gas supply line, gas regulator, NAVICIRC recirculating kit, drip leg, gas shutoff valve, and condensation and intake lines; c) wiring up the unit; d) ensuring that it was properly vented; and e) lighting and programming the unit).
