3 Steps For Locating And Repairing A Hydronic Heating Leak
Your home's hydronic heating uses a semi-closed system. Under normal operating conditions, water shouldn't enter or leave, although system pressure will vary with temperature. Since water expands as it heats up, an expansion tank prevents the excess pressure from overloading the system and causing leaks or other damage. As a result of this design, conspicuous pressure drops are usually a good indication that something is wrong. If you've noticed your pressure dropping or your other issues with your heat, your system might be leaking.
