Hello guys, im new to this, could do with a little advise. My Stuart turner monsoon pump 2 bar twin is almost 7 years old, but had suddenly lost the force or pressure it had when I turn on the shower head. It still runs the same and sounds the same, but low-pressure being delivered. Being an amatuer I took it off and checked the usual eg switch, sensors , filters and flow magnets . All seem to be fine. Capacitor appears to be fine , no signs of wear , was wondering would it be possible this it the problem. Many thanks in advance.
