Dobson Lock services on the L&L. Worst ever!
We once interrupted a mate "filling" his water tank to get enough to fill a kettle. Which took two minutes for a litre and a half ... he stopped bothering with his hosepipe, we didn't bother trying ours and we moved on.
Talking to the CRT bloke we saw there, he laughed and agreed. The maintenance yard are under strict instructions not to fill their kettle or wash their hands if someone is trying to use the shower!
Apparently Yorkshire Water were complained at years ago, and to meet their own delivery targets (pressure at meter, not flow rate) they reduced the diameter of the supply pipes.
Good water pressure, job done ... I haven't ever tried that shower.
