			Turn OFF the Water Supply
			Remember to turn off the water supply before doing any plumbing jobs. If there is not a stopcock for the tap you are repairing, you will need to turn it off at the mains. Once you have done that, turn on the taps to release the pressure and water already in the system.

			Before you can reseat the tap, you must first gain access to the seat by disassembling the tap. Whilst compression washer taps are all similar, disassembly may vary slightly from model to model. One method is shown below.

			To disassemble a compression washer tap…
			Step 1- Plug hole! Place the plug or a cloth in the plughole to stop any small parts escaping down the drain.

			Step 2 – Remove cap Remove the cap using a flathead screwdriver or blade.

			Step 3 – Unscrew top Unscrew the handle, removing both the screw and the handle.

			Step 4 – Remove tap cover Some tap designs have a decorative cap or cover, if this is the case, unscrew and remove to reveal the nut. Use an adjustable spanner or pipe grips with a cloth to prevent marking the tap body.

			Step 5 – Loosen retaining nut Loosen and remove the retaining nut with an adjustable spanner.

			Step 6 – Remove the spindle Lift and remove the spindle.

			To reseat the now exposed tap…
			Step 1- Check the size Ensure you have the right sized threaded piece and cutter for the reseater.

			Step 2 – Insert cutter Place the reseater cutter downwards into the tap body.

			Step 3 – Secure in tap Tighten the threaded section in the retaining nut screw hole.



			Step 4 – Reseat tap Twist the reseater in a clockwise direction, applying a moderate amount of pressure.

			Step 5 – Check seating Remove the tap reseater and inspect the seat. The process may need repeating several times until you have a shiny-looking seat which is smooth to the touch. A smooth seat is a repaired seat and the washer should now sit flush.

			Reassemble the tap
			Whilst the tap is disassembled, it is advisable to also check that the O-rings and washer are in full working order and replace if necessary.

			Then you can reassemble the tap in the reverse order you took it apart. The tap should now be fixed, if the leak persists, contact a plumber.
