- The pressure should be above 75 psi. If there is no air pressure within the tank, the expansion tank has failed. You will need to replace it with a new one. If there is pressure inside the tank, you'll need to check the water pressure. The expansion tank and water pressure should be similar.

To check your expansion tank pressure, you should use a standard tire gauge and press it against the valve on the top of the tank. You can then adjust the pressure with a hand pump and raise the pressure as needed. If pressure is too high, simply press against the Schraeder valve to release air inside the tank.
Jul 12, 2017 · Most expansion tanks come pressurized to 12 – 40 psi, but before you install the tank you have to match the system pressure. Start by removing the protective cover from the air valve on the tank. Use a tire gauge to check the pressure.
Heating boiler bladder-type expansion tank / compression tank pressure adjustment: For most installations the factory-set air pre-charge in an expansion tank is correct and should be left alone.
- Leaking expansion tank. Water can leak from an expansion tank at one of three places: Pipe fittings. If the pipe fittings at the top of the tank are loose, water may leak out.
- Tank pressure loss. An expansion tank can lose pressure if air leaks from the valve or the diaphragm itself. If the leak comes from the valve, more air can be added to the tank using an air compressor pump or a manual tire pump.
- Tank pressure too high. If the pressure inside the expansion tank is too high, it can be corrected by opening the Schrader valve at the top of the tank.
- Air blockage. An air blockage occurs in an expansion tank when the air inside the tank becomes trapped. The role of an expansion tank is to regulate pressure within your hot water system, but, when an expansion tank fails, the air inside can block water from flowing.
May 24, 2019 · For example: if the top of the piping circuit was 25 feet above the expansion tank connection and assuming the system is filled with water, the correct air side pressure in the tank would be: Get a low-pressure tire gauge with a scale of 0-30 psi and a bicycle pump or small air compressor.
Incorrect Air Charge: Expansion tanks need to maintain a proper air charge to function. If the air pressure drops too low, the tank won’t be able to handle pressure increases from the boiler, leading to inconsistent system pressure.
May 25, 2024 · The key to effective pressure control in an expansion tank is the pre-charge (initial gas pressure) of the air cushion, adjusted to the system’s static pressure.
