Expansion Tank Replacement in Mountville, SC

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 Mountville, SC 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 Mountville, SC.

Talk to a real person
What pressure should my boiler run at in Mountville, SC?
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 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.
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.
Do you handle steam boilers in older buildings?
Yes. Reliable Boiler Service connects owners with technicians who work on one-pipe and two-pipe steam, including air vents, pressuretrols, sight glasses and low-water cutoffs.
Are there rebates for high-efficiency boilers?
Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
