About Tankless Water Heater Expansion Tank Service

When water is heated inside a closed plumbing system equipped with a check valve or pressure reducing valve, it expands. Without a properly pressurized thermal expansion tank, thermal expansion creates pressure spikes above 150 PSI, causing relief valves to drip and stressing internal tankless copper welds. We install, test, and repressurize thermal expansion tanks across Broadview, Illinois to absorb thermal expansion and protect your tankless unit.

Tankless Water Heater Expansion Tank Service Questions

Do tankless water heaters require an expansion tank in Broadview, Illinois?

Why is my expansion tank dripping water from the air valve?

Our Navien NPE unit was leaking water from the bottom and throwing error E003. The technician diagnosed a leaking internal recirculation pump and swapped it out on the spot with an original factory part. Honest upfront pricing and super clean work.

We hadn't flushed our tankless water heater in four years and hot water pressure dropped to a trickle. Their team performed a chemical descaling flush and cleaned out the inlet filter screen. Water pressure is completely restored to day-one performance.
