Flow restrictor for toilet filling valve


Postby sfjnet » Wed May 28, 2008 10:00 pm

Hi
I am replacing my faulty toilet filler valve with a new Torbeck one. It's a very easy job, except I have one query - the instructions say the correct water pressure must be maintained using a restrictor if necessary. It then says if the pressure is below 1 bar there should be no restrictor, but I should fit one if the pressure is over 1 bar. My problem is that I have no idea what the pressure is. My toilet tank is on the first floor and is gravity filled from the loft tank. Can anyone suggest whether the water pressure for my set up (which must be fairly standard) is above or below 1 bar?
Thanks

Hi there,

If your toilet cistern is filled from the Cold Water Cistern in the loft then you will have low pressure so NO restrictor.

If it is filled off the mains the high pressure so restrictor IS needed.

Almost certainly below. It's approx 0.1 bar per metre so you'll be in the region of 0.2 to 0.3 bar I'm thinking.

You'll most likely need a pair of thin long nosed pliers to get the restrictor out.
