Valve & Vernier Insert Changing Procedure for Atriflo Crosshead Taps

From Perrin and Rowe (Avillion / Triflow / Atriflo)

It should be an easy matter to change the Valve & Vernier Insert if you follow these simple instructions from Perrin and Rowe (Avillion) and refer to the diagrams below.

1) Turn off water supplies to tap. Place plug in waste to prevent loss of small pieces.
2) Remove Boss A by unscrewing in an anticlockwise direction from Valve C.
3) Unscrew Boss A and once free pull off.

4) The Vernier Insert B may be left inside Boss A or remain on Valve C. Remove and replace if damaged.
5) Please go to stage 8 if replacing the Vernier Insert B only.

Note: Before removing the valve from the mixer, check that the replacement is the same.
6) Unscrew Valve C using a 17mm or adjustable spanner.
7) Screw Valve C into body by hand. Use a 17mm spanner to turn valve until valve stops against body. Do not tighten beyond this point

(Recommended torque setting 15Nm).

Warning: Do not over tighten valve – this may cause damage to valve, body and mounting surface.
8) Slide Vernier Insert B onto Valve C.
9) Slide Boss A onto Vernier Insert B, just enough to see if it is correctly orientated.
10) To get exact alignment on the tap it may be necessary to remove the Vernier Insert B and turn a few splines until correct alignmet can be achieved.
11) Boss A can now be screwed back over Valve C.
12) Your tap should now be ready for use, turn on supply and check carefully for any leaks.

Troubleshooting Tip:
If when you twist to remove the handle (as in Fig 2 in the diagram) and the entire handle and valve comes away as one piece then it is possible that they are stuck together with limescale. You could try pulling apart. Our guide on Removing limescale is here.
