Pride Plumbing came out and replaced a non-working Navien tankless water heater with a new Navien 240S tankless model without a NAVICIRC recirculation pump. This included 1) removing and disposing of the old water heater along with its electrical wiring, venting, and gas and water supply lines; 2) 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, drip leg, gas shutoff valve, and condensation and intake lines; 3) wiring up the unit; 4) ensuring that it was properly vented; 5) lighting and programming the unit; and 6) linking it together with two existing Navien tankless units.
