Good afternoon everyone, i have a pump fitted in my loft that powers my shower, the feed is from the immersion and the flow is intermittent coming out of the shower head. the pipework is 22mm reducing to 15 before the pump. is this possibly due to air getting into the system? i have noticed a small leak where the pipework enters the pump. the system is old, unvented. thank you 4 any advice/ideas. pump and additional pipework is approx 18 months old.
