    Hi guys, over the last year I have been noticing a steady drop in the pressure to my say shower when the likes of a tap is turned on or toilet flushed or someone using another shower ......my system is off a private well via a tank in the shed and boosted into the house the system is 10 years old and the only issue I had was a failed expansion tank failing and falling off the wall (replaced) any ideas bar the pump is on the way out :cool::pac:

    The most plausible explanation is that your boost pump is not performing as it once was. That is the first thing I would check, also check for some flow restrictions (blocked filter, valve partially closed, etc.)

    So went and back via the pipe work and cleaned out the pressure reducing cartridge ....full of brown rusty type stuff ... improved the flow
