Removing Kitchen Tap Valve Bush from Valve

Question: Hi, is there any tips on Removing Kitchen Tap Valve Bush from Valve? I have tried wwd40 but seems solid.

Answer:

The Valve Bush (Brass Ring) is a separate part that surrounds the Valve & is a part used in some (but not every) Tap.

Over time grit or debris like Limescale can cause the Bush and Valve to stick together as if they are ‘one’ part so when you remove your Valve, the Bush comes out as well i.e. the Part you remove is fatter (wider) than what you expected.

Here below is an example of a Bush and Valve together as ‘one’ piece. And beside it is a picture of the two parts separately.

To try to separate:

• Try TT Oil (which can be purchased from a DIY / Car mechanics shop shop) to loosen any debris e.g. limescale that is acting like a glue

• You need adjustable (or proper sized) spanner to fit the nut below the splines at the top of the valve.

 

• You need a vice grips to place around the brass bush (that is surrounding the middle of the valve i.e. the widest part).

• Turn both spanner & vice grips in opposite directions (moving the nut anti clockwise).
