Today I came to Bobâ€™s Springbank home because his hydronic heating system is leaking. The system (minus the boiler itself) was replaced by Clearview last October. Upon inspection I found the dirt separator is leaking from the top plug. I have removed the plug, added teflon and re-sealed the system. I filled the system back up and tested. There are no further leaks and Bob is happy with my service today.
