Kitchen Tap Valve Came Out With the Bush? Here's How to Separate Them

Every now and then, when changing a kitchen tap valve, the whole thing comes out together i.e the valve and the threaded bush.  See some examples below

Most people only realise something isn't quite right when they compare their old valve with the replacement they've bought. That is why it's always worth comparing your valve with the product photos before ordering.

If your old valve looks different, don't panic. It is a common issue on older taps and those used in hard water areas, and it doesn't usually mean there is anything wrong with your tap or that the whole tap needs replacing.

Why does it happen?

The bush is supposed to stay inside the tap while the valve unscrews from it. Over time, limescale, debris, corrosion and general wear can cause the two parts to seize together. When you undo the valve, the bush comes out with it.

How to separate the valve from the bush

First, turn off the water supply before removing any tap components.

Spray a little penetrating oil or WD-40 where the valve screws into the bush and leave it for a few minutes. If it has been in place for years, it may need a second application.

Hold the bush firmly using a soft-jawed vice or adjustable spanner. Wrapping the bush in a cloth first will help protect the finish.

Carefully turn the valve anti-clockwise. It should start to free up and unscrew from the bush. If it doesn't move straight away, don't force it. Another spray of WD-40 and a bit more time is usually better than applying too much pressure.

Before putting it back together

Once the valve and bush are apart, give both a clean. Wipe away any dirt, limescale or old residue from the threads and check that neither part has been damaged.

Refit the bush into the tap body first, making sure it's fully tightened, then install the replacement valve.

Turn the water back on and check that the tap operates smoothly without any leaks.

When should you replace the bush?

If the bush is cracked, the threads are damaged or you simply can't separate it from the valve, it's usually easier to fit a replacement.

We stock replacement bushes for many leading kitchen tap brands, including Perrin & Rowe, Franke, Abode, John Lewis, Howdens, CDA, Bristan, San Marco, Carron Phoenix and many more.

A quick tip

One of the biggest mistakes is trying to force the valve apart. The bushes are usually brass, which is softer than most tools. Too much force can damage the threads and turn a simple repair into a more expensive one.

A little patience and some penetrating oil will usually do the job.  If in doubt, purchase a new bush!

If you're unsure which replacement valve or bush you need, compare the existing parts carefully before ordering. Many taps look similar but use different thread sizes and valve types.
