Citywide Coverage
Every neighborhood in San Rafael has homes with pressure regulators that create closed systems, and we serve all of them. We also install expansion tanks for townhomes, condos and small commercial buildings.
Experienced Team
The team understands how pressure regulators, check valves and backflow devices create closed systems. That knowledge helps them diagnose dripping relief valves and fluctuating pressure accurately.
Safety-First Approach
Thermal expansion can push household pressure past 150 psi, the point where a temperature and pressure relief valve opens. A properly installed expansion tank keeps pressure in a safe range and protects the heater from strain.

New Expansion Tank Installation in San Rafael
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.
Preventative Expansion Tank Maintenance in San Rafael, CA
Beyond installation, regular checks and maintenance of your water heater expansion tank help it keep working properly. FBL Plumbing offers preventive maintenance in San Rafael, CA to inspect your expansion tank's air precharge, check for leaks and confirm proper mounting. This proactive approach helps identify potential issues before they lead to system failures, extending the life of both your tank and your water heater.
Expansion Tank Replacement in San Rafael, 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 clear sign it has failed. We replace failed tanks with a correctly sized new unit and check the precharge before installation.
Watts Expansion Tank Installation in San Rafael, CA
Watts is a leading manufacturer of high-quality plumbing products, including durable water heater expansion tanks.

Our technicians are experienced with Watts products and handle proper installation.
Tankless Water Heater Expansion Tank Integration in San Rafael, CA
While tankless water heaters usually have different pressure dynamics, an expansion tank can still be beneficial or even required in certain setups or by local codes in San Rafael, CA. We assess your tankless unit and plumbing configuration to determine whether an expansion tank is necessary, especially with higher flow rates or a recirculation pump. Our technicians are skilled in integrating expansion tanks cleanly with many tankless models, keeping them running efficiently and protecting your plumbing system.
Replacing Old Expansion Tanks in San Rafael
Expansion tanks do not last forever, and an old, waterlogged or corroded tank offers no protection. If your existing tank in San Rafael is showing signs of failure, such as a dripping relief valve or fluctuating water pressure, it is time for a new one. We carefully remove the old unit, dispose of it responsibly and install a new, correctly sized expansion tank. This proactive replacement prevents costly damage to your water heater and plumbing system and restores proper pressure control.
Commercial and Multi-Unit Expansion Tanks in San Rafael
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 limit hot water interruption for tenants or customers.
Brands and Tank Materials in San Rafael, 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. Rural properties around San Rafael often rely on private wells, which may need treatment for iron, sediment, or other minerals. 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.

An expansion tank is important in San Rafael because water expands when heated. Without a tank to absorb this expansion, the increased pressure can damage your water heater, pipes and fixtures. Plumbing contractors here must hold a state contractor license, and permits are typically required for water heaters, repiping, and sewer replacements. Many local plumbing codes also require expansion tanks for safety and system longevity.

When water heats up, it expands. Without an expansion tank, this expanded water has nowhere to go, increasing pressure within your closed plumbing system. This constant pressure can quickly wear out water heater components and relief valves and even cause leaks or ruptures. The expansion tank absorbs this excess volume, protecting your whole system.
An expansion tank is essential in closed plumbing systems to absorb the increased water volume and pressure that occur when water is heated. Without it, thermal expansion can damage your water heater, pipes and fixtures, leading to leaks and premature system failure. Many local codes in Northern California require them.
If your home has a pressure reducing valve, check valve or backflow preventer on the main, you probably have a closed system that needs one. Many local codes require it whenever a water heater is installed on a closed system.
