16/17 YO system. In 2013 the recharge interval started to get very short, 1-2 months. Dripping from the tundish was the indicator. As per manual recharging the bubble fixed the problem.
This was also accompanied by a squeal from the prv.
Prv was replaced in August 2013 and then the frequent recharge also stopped. First was in the spring but Since then I'm back to doing this every 2 months.
When the drip occurs there's also a noticble pressure in the hot water system, you can feel it as you slowly turn on a tap.
I guess the pvr was not the cause, just a side effect.
Google tells me I shouldn't be doing this so frequently so putting it out there for some welcome advice.
