Expansion Tanks With Tankless Water Heaters in Hempstead, NY

Tankless water heaters hold very little water, so thermal expansion is minimal in most homes. However, homes with recirculation loops, storage buffer tanks or certain closed system setups may still benefit from an expansion tank. We evaluate your system and only recommend a tank when it serves a genuine purpose. This keeps you from paying for parts you do not need.

New Expansion Tank Installation in Hempstead

If your home has a pressure reducing valve and no expansion tank, the water heater is probably seeing a pressure spike every heating cycle. We install a new tank on the cold water supply near the heater using a tee and short nipple. The air side is precharged to match your static pressure, usually between 50 and 70 psi. We then run the heater and watch the gauge to confirm pressure stays steady.

Expansion Tank Replacement in Hempstead, NY

Expansion tanks wear out over time as the internal bladder or diaphragm fails and the tank fills with water. A waterlogged tank feels heavy, and tapping it produces a dull sound all the way up instead of a hollow top. Pressing the air valve and getting water instead of air is a sure sign it has failed. We replace failed tanks with a correctly sized new unit and check the precharge before installation.

Expansion Tank for Tankless Water Heaters in Hempstead, NY

While tankless water heaters do not store hot water, an expansion tank can still be beneficial, and sometimes required, in Hempstead, NY plumbing systems. If your tankless unit is part of a closed system, an expansion tank can help absorb pressure spikes from the cold water supply or cut down wear on components. Our plumbers assess your tankless setup and local codes to determine whether an expansion tank is necessary and recommend the right solution for your system's longevity and performance.
