Low water pressure at electric shower.

[MickBrown]

Had an electric shower problem, turned out to be low mains water pressure coming in to shower. Kitchen tap water pressure is fine, bathroom cold tap water pressure seems low but better than the shower. Haven't yet confirmed if bathroom cold taps are mains or tank fed. All pipes are boxed in either tiled or decorative cladding. I am going to start under the bath as the pipe to the shower (shower over bath) comes up from below bath.

Any ideas as to the best way to tackle this problem would be appreciated.

First check if supply to shower is definitely mains. Then check filter inside shower is clean and then make sure flow is good coming from shower pipe by flushing it through.
Got to watch that isolating valve isn't blocked

Turn the cold mains off at the stop tap where it enters the property.

All the taps that stop working are mains.

Tx Best, yes shower is mains. Shower removed and water from supply pipe is just a trickle, no isolating valve although there could be under the bath. Didn't have time to investigate the other day so going back next week.
