Boiler Repair FAQ

Questions we hear

My relief valve is dripping. Is that dangerous?

It’s a sign the boiler needs attention. Don’t cap, plug or tie off the valve. It’s there to protect you. Call us at 215-785-6161.

One room is cold but the rest of the house is fine. Why?

On a boiler system that usually points to that zone: a circulator, a zone valve, a thermostat, or air in the line. A technician can track it down.

What should my boiler pressure be?

It depends on your system and your house. Your technician can tell you what’s normal for your boiler. If the gauge looks different than usual, give us a call.
