Non return valves fore bathtaps All aspects of plumbing questions and answers, help, tips and information

[rontill]

i have just bought a bath mixer tap that says i need non return valves, but i didn't seem to have any when i took off the old taps. Do I need to put them on if maybe they may be under the floorboards etc. ?

rontill,
The non-return valves are only needed if you have mains feeding the tap.
