Expansion Tank Replacement in Raleigh, 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 Raleigh, 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 Raleigh, NC.

Talk to a real person
What pressure should my boiler run at in Raleigh, 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.
Why is the relief valve on my boiler dripping?
A relief valve that drips or opens near 30 psi usually means a waterlogged expansion tank or a fill valve letting too much water in. Replacing the valve alone rarely fixes it.
Should I repair or replace my boiler?
Repair makes sense for parts like igniters, circulators and zone valves. A cracked section, a leaking heat exchanger or a boiler where parts are no longer made usually points to replacement.
My boiler is running but the house is cold. What should I check?
Look at the pressure gauge, listen for the circulator pump, and feel the pipes leaving the boiler. Hot boiler with cold pipes usually means a pump or zone valve problem.
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.
