Expansion Tanks With Tankless Water Heaters in Helena, MT
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.

Expansion Tank Replacement in Helena, MT
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.
Code-Compliant Installations in Helena, MT
Local plumbing codes in Helena, MT frequently require expansion tanks, particularly when a backflow preventer or pressure reducing valve creates a closed system. Montana uses a statewide plumbing code based on the Uniform Plumbing Code, and plumbers are licensed by the state. DFV Plumbing stays up to date with current regulations and makes sure every expansion tank installation is fully compliant. We obtain any required permits and perform installations that pass inspection, safeguarding your home and avoiding fines or insurance issues. Trust us for installations that meet or exceed all local requirements.

We choose the correct size and model to match your water heater's capacity for full system protection.
New Expansion Tank Installation in Helena
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 & Upgrades in Helena
If your existing expansion tank is old, leaking or no longer working correctly, DFV Plumbing offers professional replacement in Helena. We can also upgrade your current tank to a larger or more efficient model if your plumbing needs have changed. A failing expansion tank can cause the same pressure problems as having no tank at all. Our team will promptly diagnose the issue and install a new, high-quality tank, restoring protection to your water heating system.
Tank Sizing and Placement in Helena
Correct sizing and placement are key to an effective water heater expansion tank in Helena. An undersized tank will not provide adequate protection, while an oversized one is an unnecessary expense. We accurately calculate the required tank volume based on your water heater's capacity, system pressure and average water temperature. Placement matters too, typically near the water heater on the cold water inlet line, with easy access for future maintenance or inspection.
