Hi There,
I have a shower in my bathroom which loses water pressure after about a minute. The hot and cold feed seems to be fine and the water pressure to the bath and WC is normal. The hot water to the shower is supplied from a combi boiler and is about ten years old, although only used intermittently. The shower head manufactures name is Bristan so I am assuming the shower is the same. I am wondering if there is a valve inside that would need replacing.
Many Thanks
