Who on earth designed a tap with a double thread (one of which is inverted ?)

I have two here that have started leaking and I suspect the sprog has been testing her strength after leaving the taps to drip continuously over the Christmas peiod.

The hot tap on the bathroom sink has a square looking circlip on it which is above the main device , just below the tap / handle itself, the cold tap has same but is below the main cover.

The idea (I think behind the double screw system is to ensure the neoprene washer is not twisting as it is driven down onto the valve but is there a specific amounnt of internal thread required before the tap interior drives itself out of the housing.

Does more screwing (ooooerrr) force the circlp through the housing and into the open air so that the tap no longer shuts off the water ?

I don't want to spend yet another half day under a basin replacing things, moreso since the taps are over ten years old and discontinued, I had enough trouble finding a similar pitch / length screw to fix the bath tap down two years back when the other half sheared it off.

Do you know the make/model of your tap??

Have you looked for the correct drawing for it?? (I would assume so)

Usually the packing nut (or gland nut) is where the spindle is threaded into, this allows the faucet (tap) to let water flow when you turn the handle, the packing nut needs to be big enough to allow for the removal of the washer assembly for replacement.

Here stateside most faucet manufactures have gone to a total replacement option, you look up the correct part in a book by manufacture/model type and replace the whole assembly at one step.

Something like this from Home Depot......Search Results for faucet stem at The Home Depot

You can get the internal mechanism as a replacement assembly so no need to disturb the main body

Indeed pgh13 is correct, there are also a number of types available, I have problems with the plastic inserts which rely of pressure from either end to maintain their function
see here

It's over ten years old, so no guarantee. Everything was sourced local by the plumber ( dearly beloved , RIP etc)

The local wholesaler is Jewsons, the nearest specialist is a bit further, but they don't sell complete bathrooms.

One tap has a different thread to the other , luckily I was able to use a bolt from the LNB odds and sods to make it all work, the other looks one size bigger, I haven't measured it.
