What it is
Your supply's pressure and flow depend on your hot-water system, the mains in your street, the pipe sizes and how high the bathroom is.
Good for
Choosing well
Matching fittings to your system avoids weak showers.
What to weigh up
Rainfall heads and jets
Need plenty of flow and hot water.
Pumps
Can help on tank-fed systems, never on mains-fed ones.
Check each tap
Every tap and shower lists a minimum working pressure. On a low-pressure system, choose fittings made for it.
