Expansion Tank for Tankless Water Heaters in Longview, WA

While tankless water heaters do not store hot water, an expansion tank can still be beneficial, and sometimes required, in Longview, WA 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 ideal solution for your system's longevity and performance.

Expansion Tanks With Tankless Water Heaters in Longview, WA

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 real purpose. This keeps you from paying for parts you do not need.

Brands and Tank Materials in Longview, WA

We install potable-rated thermal expansion tanks from brands such as Watts, Amtrol and A.O. Smith. Potable tanks use a butyl diaphragm and a lined interior so water never touches bare steel. Municipal water west of the mountains in Washington is generally soft, while supplies on the drier east side tend to run harder. Stainless steel connections hold up against corrosion from hard or aggressive water. We avoid tanks designed only for hydronic heating, since they are not approved for drinking water.

Pressure Reducing Valve and Expansion Tank Pairing in Longview

Many homes see high incoming pressure, so pressure reducing valves are widespread. The PRV protects your fixtures but also turns your plumbing into a closed system, which makes an expansion tank necessary. We test the PRV output and replace it if it is creeping or failing. Pairing a healthy PRV with a correctly charged expansion tank gives you stable pressure throughout the house.
