We have a whole-house rainwater harvesting system (except for the drinking water taps), and in recent years I have had to replace the PRV on the hot water tank (corroded/broken spring) and a blanking plug (pinhole leak). There is a blue-ish deposit in the shower as well which I imagine is copper coming off the inside of the pipes.
I have read that rainwater is acidic because of the dissolved CO2, is this what is eating the pipework? Is it a common problem and what should I do to prevent it?
TIA
