Brands and Quality Products in Mountain View, CA
FBL Plumbing uses only high-quality, durable expansion tanks from reputable manufacturers known for reliability. We work with trusted brands like Watts, Amtrol and Z-Flex, so you receive a product built to last in your Mountain View, CA home.

Brands and Tank Materials in Mountain View, CA
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. Homes on hard water see scale on fixtures and water heaters, while very soft water can be mildly corrosive to older copper pipe. 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.
Commercial and Multi-Unit Expansion Tanks in Mountain View
Apartment buildings, restaurants and offices with large commercial water heaters or multiple tanks need larger expansion tanks sized for total system volume. We calculate requirements for the entire hot water system, including any storage tanks and recirculation loops. Larger tanks are floor-mounted with proper supports. We schedule work to minimize hot water interruption for tenants or customers.
New Expansion Tank Installation in Mountain View
If your home has a pressure reducing valve and no expansion tank, the water heater is likely 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 stable.
Standard Water Heater Expansion Tank Installation in Mountain View
Our standard installation service covers traditional tank-style water heaters, with the expansion tank correctly tied into your cold water supply line. We use high-quality, pre-charged diaphragm tanks designed to absorb thermal expansion efficiently. This keeps excessive pressure from building up in your system, which is crucial for prolonging the life of your water heater and preventing damage to fixtures and appliances. We always test the system carefully after installation to confirm proper performance and compliance with local Mountain View regulations.
Residential Expansion Tank Installation in Mountain View
For homeowners in Mountain View, a properly installed water heater expansion tank is crucial, especially with so many closed plumbing systems. This device absorbs the increased volume of water when it heats, keeping excessive pressure from building up in your pipes and water heater. Our team makes sure the tank is correctly sized for your water heater's capacity and your home's water pressure, maximizing its protective benefits. We handle all connections and secure the tank according to industry standards, giving you peace of mind.

Expansion Tank Replacement in Mountain View, CA
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 installing.
