How Do You Fix A Leaking Steam Boiler?
A steam boiler heats a home by boiling water which rises through pipes as steam and escapes through radiators. As a boiler ages, it is vulnerable to rust and mineral build-up that can cause leaks. While a homeowner may be able to locate leaks, it is recommended to let a professional heating, ventilation and air conditioning (HVAC) technician do the repairs (or replacement if necessary), since special equipment is needed to fix the leak properly. Check the sight glass on the side of the boiler weekly. The ball inside should be at 1/2 to 3/4. Check the glass for sediment that may cause decay inside the boiler. Add new water if necessary by opening the valve below the sight glass. Then check it again by shutting off the valve and watching water come back into the chamber. If it rises quickly, it’s fine; if it trickles in, call a professional. Blow down the system monthly by draining and refilling it. Check your manuals, or a licensed HVAC technician can show you how to do this quick proce
