Rinnai tankless popoff valve problem
Hey guys, new to the board...
I have a rinnai tankless outdoor gas unit (the big 9.4 gpm one) anyway, it's been installed about 2 years now with no real problems. All of the sudden yesterday, I noticed a big puddle in the yard. The popoff valve was pouring water on the ground like it was a garden hose. I turned off the unit and it stopped. I pushed in the popoff felt a click, and turned it back on. Turned on the shower and had hot water, and the popoff wasn't open. Then when I turned off the water, the popoff again opened and started spilling hot water on the ground again.
