At 24/7 Plumbing Co., LP, we install and service water expansion tanks to help protect your plumbing system and water heater from excess pressure. A properly installed expansion tank prevents unnecessary strain on your pipes and fixtures, extends the life of your water heater, and helps your system run more efficiently.
A water expansion tank is a small, pressurized tank that absorbs excess water pressure caused by thermal expansion. When water is heated inside your water heater, it expands, increasing pressure within the plumbing system. Without an expansion tank, that extra pressure has nowhere to go, which can damage your pipes, fittings, or water heater.
The expansion tank acts as a cushion, using an internal air bladder to absorb the pressure and maintain a balanced system. This keeps your plumbing safe and reduces wear on valves, joints, and fixtures. It is a small component that makes a big difference in maintaining long-term reliability.
Not every home has one, but most modern plumbing codes now require expansion tanks, especially in homes with closed water systems or pressure-regulating valves. If your home has a newer water heater, fluctuating water pressure, or you hear unusual noises in your pipes, you may need an expansion tank installed.
Other signs include dripping from the temperature and pressure relief valve on your water heater or visible movement in your plumbing lines when hot water is running. These symptoms often indicate that your system is experiencing more pressure than it should.
Our team at 24/7 Plumbing Co., LP can inspect your system and determine whether an expansion tank is needed to bring your plumbing into compliance and protect it from damage.
A quality water expansion tank typically lasts between five and ten years, depending on water quality and pressure levels. Over time, the internal bladder can lose air or rupture, reducing its ability to absorb pressure. If the tank feels heavy with water or produces a dull sound when tapped, it may be full of water and no longer working properly.
Regular inspection helps catch problems early. When we replace a water heater, we always check the expansion tank to ensure it is functioning and properly pressurized. Installing a new tank when needed helps maintain even pressure and prevents future repairs.
Incorrectly installed or poorly pressurized expansion tanks can create more problems than they solve. A tank installed on the wrong side of the system or without proper support can lead to leaks, vibration, or water hammer. If the air pressure inside the tank is not correctly balanced with your system pressure, it can cause premature failure of both the tank and the water heater.
At 24/7 Plumbing Co., LP, our licensed technicians install each expansion tank according to manufacturer specifications and local code requirements. We use pressure gauges to set the tank precisely, ensuring it performs its job safely and effectively.
Excess pressure can shorten the life of your entire plumbing system. A properly functioning water expansion tank keeps your water heater, fixtures, and pipes protected from damage caused by thermal expansion. Whether you need a new installation, an inspection, or a replacement, 24/7 Plumbing Co., LP provides reliable service and long-term peace of mind.
