Not that draining off the steel compression tank is an issue for me I need some advice.
What do you all use for leak proof valves? Knife gate valves with replaceable stem packing?.
The Nibco 3/4" ball valves I have were new three years ago and they are both bypassing allowing
water to fill the steel compression tank over time.
Its going to be a summer repair job after the heating season and I have to plan ahead and decide whether I just want to install a physical break with two facing boiler drains and use gasketed sill cock caps at both connections and a short washing machine hose to fill it when and if the need arises or a knife gate valve at the feed end of the copper line that feeds the system when needed. I also need to repack the stems of the gauge glass as well.
NO; I am not going to rip out my 15 gallon steel compression tank as it works very well. The steam chest barely registers any pressure and the system runs silently when I have a heat call or the system dumps heat in the single heating loop.
