Loose Kitchen Tap

Monobloc mixers usually come with a horseshoe shaped metal plate & a matching rubber washer. Have yiu got the metal plate? You should have this lot

Are you sure the rubber washer does not go on top of sink?

Well, there are no assembly instruction but there is a groove on the underside of the tap body and a matching O Ring which I assume goes on the top of the sink to form a waterproof seal. Then there is a wide thread probably about 30mm which goes through the sink and a rubber washer and a nut which I have assumed goes on the underside.

I stand to be corrected on any of this since, as I say, there are no instructions.

Nope. Nothing like that. The tap is one of these:

As I tighten the nut the rubber washer compresses and stops the tap rotating in the hole but there is enough give to make the tap wobble a bit when turned on or off.

I have thought about replacing the rubber washer with a similar sized nylon one but given nylon's slipperiness I am not sure that that would not make it easier to rotate the tap, thus replacing one problem with another.

Sure it's not "give" in the sink top allowing the tap to wobble?

There is a little give in the sink but not as much as the tap moves. If that makes sense.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Andrew May saying something like:

These monoblock types are notoriously wobbly if the sink is a bit on the thin side. You can fit a load-spreading washer underneath if clearance allows.

Never seen the like - thank heavens. Who designs this stuff?

Reckon it needs a metal plate between the sink & the washer/nut.
