Hello @dani335711 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your wall taps.

I suggest looking for a large 12g or 14g screw and screwing it into the middle of the plastic jumper valve. Once it is secure, I recommend gently pulling it out so that the screw takes the plastic body with it. Violent pulling actions might ruin or compromise the hold of the screw. Your objective is to get the jumper valves body to loosen up and come out as you slowly pull on the screw.

Let me call on our experienced members @Nailbag, @Dave-1 and @Noyade for their recommendations.

If you need further assistance, please let us know.

Hello @dani335711 

My next suggestion is to spray it with WD40 and use a larger screw. Small screws with small bodies will not be effective. Another thing you can try is to use a heat gun (if you have access to one). Use the heat gun on high setting to soften the plastic body of the jumper valve. Once it starts to get pliant try the long nose pliers again.

Please remember to wear personal protection such as gloves and goggles when working on your project.

Hi @dani335711 

I agree with @EricL suggestions of techniques but I think you might need to be more forceful going back to the screw idea. If it's an all-plastic valve, then the heat-gun/hair dryer idea may help, but if it has a metal back then it will expand with the heat. I suspect though it's plastic since the stalk has separated. 

I would put something like a 75mm screw back in giving more leverage and really try and twist it in a random way rather than pulling straight out.

Last resort obviously is getting a plumber in who would have experienced this scenario plenty of times before.

Good morning @dani335711 

The guys have already suggested two of the most likely ways I know to remove the base of the washer. I prefer working away with a pair of needle nose pliers where the nose is small enough to go through the center hole. Whichever way I think patience and fource mixed together will be the way to go. The tolerences are tight but the washer has gone in so it must be able to come out is what I tell myself when I get fed up with something like this.

Same here@Dave-1 .

Although - I do have an autistic son who cannot stop over-tightening taps and destroying washers. I have a 'kit' always ready to go and have become quite adept at keyhole surgery. Artery forceps for the stem and the rubber carcass is removed with a 'scraper.'

I've never lost a patient  - yet.

Thank you,

I have successful removed it and installed new tap in, but now it is leaking once I turn the tap on, I am not sure if it’s too tight or the new tap it not the right one

Good Evening @dani335711 

Could you describe were it is leaking from? The spindal (center bit) or the larger tap base? Also was there any washers that you used and how did you tighten up the tap base?

Leaking between the red circle and the other side and I used spanner to tighten
