On a combi boiler, if the taps on the filler loop are left open will the PRV fail very soon? Does it depend on how often the hot water or heating is used?
The PRV on my tenant's boiler has failed. It happened shortly after the heating was turned on for the first time since the summer. The plumber says it needs a new PRV and was caused because the taps on the filler loop are open. The tenant's say they have not touched the taps. The last time I know for sure when the taps would have been used was about 3 months ago when a new timer had to be fitted.
If the filler loop taps are left open, would it fail much sooner than 3 months, or was it only when the heating started that the open taps caused the pressure problem?
