Hard Grey buildup in radiant system
I have a client who is getting a hard grey buildup in his radiant system, making valves stick etc. it's o2 barrier pipe, geo system with a buffer tank, fully closed and when they close the makeup valve there is no pressure drop, so no leak.
I'm kind of astounded at how much buildup can occur apparently from the single fill of water... admittedly, it's probably about 200 gallons of water, but still.
buildup is hard enough to require chiseling with a screwdriver to remove.
anyone else ever seen such a thing? client will send out a water sample for testing but would love to hear if anyone's seen it before.
