Expansion Tank Replacement in Fairfield, CT

Water expands when it heats, and the expansion tank gives it somewhere to go. When the tank's internal bladder fails, the tank fills with water and system pressure climbs every time the boiler fires.

The usual sign is a relief valve that drips or blows at 30 psi on a hot water boiler. Tap the tank: a healthy one sounds hollow at the top, a waterlogged one sounds solid all the way. Older steel compression tanks hung from the basement ceiling can waterlog too and need draining.

Reliable Boiler Service connects Fairfield, CT homeowners with technicians who replace the tank, set the air charge to match the cold fill pressure (often around 12 psi), and check the pressure reducing valve while they are there. A tank charged wrong works almost as badly as a failed one.

Left alone, it wears out relief valves and stresses every joint in the system.

Expansion Tank Replacement FAQs

Frequently asked questions about Expansion Tank Replacement

Questions we hear most often about Expansion Tank Replacement in Fairfield, CT.

Talk to a real person
What pressure should my boiler run at in Fairfield, CT?
Most residential hot water boilers sit around 12 to 15 psi when cold and stay under 30 psi when hot. Steam boilers are different and run at a fraction of a pound.
Is a combi boiler a good fit for my home in Fairfield, CT?
A combi suits homes with one or two bathrooms and a gas line big enough for its hot water demand. Larger households often do better with a heat-only boiler and an indirect tank.
Why are my radiators cold at the top?
Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.
Why does my steam heat bang and hammer?
Banging usually comes from condensate trapped in a pipe that lost its pitch or a radiator tilted the wrong way. A pressuretrol set too high makes it worse.
Can I convert my oil boiler to gas in Fairfield, CT?
If gas service is available on your street, yes. The job includes a new boiler, a properly sized gas line, a vent or chimney liner, and removal or abandonment of the oil tank.
