Match size and rotation

Measure the thread — 1/2" for basin/bath taps, 3/4" for bath and kitchen. Hot side rotates anti-clockwise to open; cold clockwise.

Fit

Isolate. Remove decorative shroud and crosshead. Old gland unscrews with adjustable spanner. Fit new headwork with fibre washer under seating.
