Expansion Tank Replacement in Villa Maria, PA
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 Villa Maria, PA 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.
