First post as I can not figure this one out. I have a hot water boiler heating system, gas fired, with an HTP SuperStor indirect hot water tank. I'm on well water and have a water softener and two whole house filters for my water.
Three days ago I found my high pressure relief valve tripped and the pressure on the boiler was at 30 vs the usual 20. I drained down the boiler pressure from the spigot on the boiler and it held steady at 20. 4-5 hours later, it's back to 30 and relieving pressure through the valve.
I suspect that the element in the SuperStor has failed and pressured water from the tank is flowing back into the element and thus back into the home heating system. I had this exact problem only 4 years ago. I know because I cut the tank open and could see the corrosion and break in the element. The SuperStor was replaced 4 years before that so these tanks/elements are failing on me every four years. That seems nuts.
The tank is guaranteed for life, but the plumber fee is not so it's still costing me.
I read about electrolysis and the house electrical is grounded separate from the water/plumbing system and the water quality report done 9 years ago doesn't show any extreme mineral levels.
How do I go about troubleshooting this and ruling out other causes of overpressurization. Thanks all!
