Tankless water heater installation, repair and descaling for homes in Lodi, Acampo and the surrounding area, with the gas line, venting and valves the job actually needs.
A tankless water heater heats water only when you open a tap, so you never run out mid-shower and you stop paying to keep 40 or 50 gallons hot all day. The catch is that tankless units are far less forgiving of a sloppy install. AccuFlow handles tankless water heater installation in Lodi, Acampo and the surrounding towns, including tank-to-tankless conversions, and we repair and descale existing units. We’re an authorized warranty and service provider for Navien, Rinnai, Noritz, Rheem and other major brands, size each unit to your fixtures and household, and set it up with the gas line, venting, condensate drain and service valves it needs to last.
Old tank out, new tankless on the wall, with the gas line and venting upgraded to match.
Ignition failures, error codes, temperature swings and low flow diagnosed and fixed.
Yearly descaling through the service valves to keep scale out of the heat exchanger.
Covered parts handled through the manufacturer warranty when a component fails.
Tankless units are sized by flow, not tank capacity. We add up the fixtures your household runs at the same time (two showers and a dishwasher on a winter morning is a common test) and the temperature rise from your incoming water to your shower setting. Undersize the unit and the water goes lukewarm when a second shower turns on; oversize it and you pay for capacity you never use. Larger homes sometimes need two units linked together. We do the math before we quote, so the tankless water heater fits the way your family actually uses hot water.
Swapping a tank for a tankless unit is more than a one-for-one replacement. Most gas tankless heaters need a larger gas line than the old tank, because they burn a lot of gas for short periods; we check your meter, pipe size and run length first. The old vent usually can’t be reused, so the new unit gets its own stainless or PVC venting, plus a condensate drain on high-efficiency models. We also add isolation valves so the unit can be descaled every year. Most conversions are finished in a day, depending on how much gas and vent work the house needs.
Most tankless water heater repair calls come down to scale, ignition or electronics. Hard water leaves mineral scale in the heat exchanger, which shows up as error codes, fluctuating temperature and reduced flow. We descale the unit with a flush kit through the service valves, clean the inlet filter, and check the igniter, flame sensor, flow sensor and control board. Many manufacturers require regular descaling to keep the heat exchanger warranty valid, and we handle warranty parts when a covered part fails. Comparing options before you commit?

Accuflow Plumbing were excellent to do business with. Mikey and Tristan were very professional, knowledgeable, and did an outstanding installation job of a Navien Tankless Waterheater. They were both fast and efficient and left the worksite spotless. We highly recommend their services and would do business with them again in a heartbeat.
Great experience, 2nd time using them. Replaced an old water heater with a tankless unit in less than a day, everything works great!
