the carver water pump on my Lunar Quasar 544 2015 works fine on mains but on a fully charged battery only, it carries on running for ever after the taps have been turned off. This can be corrected by adjusting the pressure regulator and my question is should it need to be.
If the pressure regulator is set for correct operation on the battery then I'm getting lower pressure water that I could be when returning to mains. Also the pressure regulator has to be continually adjusted as the battery voltage drops if I'm on battery only, for a couple of days. The worst is if I don't spot the pump is not switching off then it continues to run until the battery is flat which takes about 5 hours, which is kind of annoying when you've gone out for the day from a CL with no mains.
The main dealer gave the impression that that was the way it was and there is no fault, I'm not so sure.
