Expansion Tank Replacement in Cary, NC

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 Cary, NC 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 Cary, NC.

Talk to a real person
What pressure should my boiler run at in Cary, NC?
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.
How long does a boiler last?
Cast iron boilers often run 20 to 30 years with yearly service. Wall-hung condensing boilers tend to have a shorter life and depend more on regular maintenance.
Do condensing boilers work with old cast iron radiators?
They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.
How often should a boiler be serviced?
Once a year, ideally before the heating season. Steam boilers with a float type low-water cutoff also need regular blowdown through the winter.
How do I know if my boiler is the right size?
A room-by-room heat loss calculation is the only real answer. Boilers that short cycle on mild days are often oversized for the house.
