Expansion Tank for Tankless Water Heaters in Novato, CA
While tankless water heaters do not store hot water, an expansion tank can still be beneficial, and sometimes required, in Novato, CA 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 reduce 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.

New Expansion Tank Installation in Novato
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 stable.
Replacing Old Expansion Tanks in Novato
Expansion tanks do not last forever, and an old, waterlogged or corroded tank offers no protection. If your existing tank in Novato is showing signs of failure, such as a dripping relief valve or fluctuating water pressure, it is time for a replacement. We expertly remove the old unit, dispose of it responsibly and install a new, correctly sized expansion tank. This timely replacement prevents costly damage to your water heater and plumbing system and restores proper pressure control.

Standard Water Heater Expansion Tank Installation in Novato
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 built 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 thoroughly after installation to confirm proper performance and compliance with local Novato regulations.

A waterlogged tank feels heavy and sounds solid when tapped near the top. Water coming out of the air valve when pressed is a sure sign the bladder has failed.
Most expansion tanks last 5 to 10 years. Hard water and high pressure can shorten that life, so we check them during water heater service.
A dripping temperature and pressure relief valve often means thermal expansion is pushing pressure too high. A failed or missing expansion tank is the most common cause.
We install high-quality expansion tanks from leading manufacturers known for reliability and durability. Our go-to brands include Watts, Amtrol and Z-Flex, so you receive a product built to last and perform reliably.
We install potable-rated tanks from Watts, Amtrol and A.O. Smith. Each is approved for drinking water and built with corrosion-resistant connections.
While less common than with traditional tank water heaters, an expansion tank can still be required or beneficial for tankless water heaters, especially if your home has a closed plumbing system because of a backflow preventer or pressure reducing valve. We will assess your setup to provide the best recommendation.
A typical water heater expansion tank can last anywhere from 5 to 10 years. Homes on hard water see scale on fixtures and water heaters, while very soft water can be slightly corrosive to older copper pipe.
