Water Heater Expansion Tank Leaking

An alternative to installing or changing a water pressure regulator when building water pressure is occasionally 80 psi or higher is the installation of an expansion tank to temporarily absorb that pressure increase.

Water heater expansion tank leaking.

The risk of pressure damage from thermal expansion is seldom a concern for tankless water heaters but if you own a tank style heater your plumbing system may be at risk. The changes in pressure inside the expansion tank can bring about the degradation of the water heating system and cause leaks. Some water heater systems include a smaller tank called the expansion tank. After you are sure that you have resolved the leaks it is time to turn on the valve between the boiler and the expansion tank.

Otherwise heated water cannot expand and instead increases pressure until some component of the system leaks or explodes. An expansion tank will give the water somewhere to go when it expands and the tprv on the water heater will stop causing problems. This secondary safety device is designed to absorb excess hot water.
