Weak gravity shower
A loft tank already fills the pipe and the shower is weak. The KATSU 151414 is about £69.99, with 3.9 from 178 reviews, 260 W, 20 litres per minute and 15 m head, auto or manual. It is not self-priming and the plug is not supplied. Skip it if the pump must suck from a butt below it.
