Kitchen tap turning when we switch it on and off

kippers

Hi all, I know absolutely nothing about plumbing but i cant call a plumber as we are shielding.  Our kitchen hot tap keeps turning round everytime we switch it on and off.  We keep tightening the screw underneath the sink but the tap still turns.  I took a photo ( see below) and did a bit of googling and i think i need to buy a split klick top hat washer.  On a video i saw it said it is easy to fit and you just undo the screw and click it on and then tighten the screw back up ....here the part i think i need.... https://www.stevensonplumbing.co.uk/plastic-split-top-hat-washer.html?gclid=EAIaIQobChMI1fient3r2QIVz5TtCh0_dQV0EAQYAyABEgK7fPD_BwE

my question is....is this the part i need and do i need to switch the water off while i put it on?  Thank you for any advice given XXX

Yes, that might work and no you don't have to switch off the water as long as you make sure you're just loosening and  tightening the back nut and not the flexible tail nut.

Yes you need a top hat but fitting one to that will do nothing because the nut is broken, you will need to turn the water off, undo the flexi connector, remove the nut & then fit a top hat & a new 1/2" nut (get a brass back nut from any of the sheds or a plumbers merchant) then reconnect the flexi, if you aren't able to do that yourself then you will have to wait for a plumber or handyperson

Is the back nut broken? All I can see is the rubber washer has broken, the back nut is still there, unless it's a flanged back nut then yes you're correct the flexi connector will have to be removed and a new back nut fitted.

All tap back nuts are flanged or they would pull straight through the hole

Thank you, im not sure i can do that so we will just have to put up with it until we get vaccinated and get a plumber in.  Oh well, thank you so much for your help all XXX

Wanna bodge? :-)

Undo that nut as far as possible (until it hits the flexi connector) and clean thoroughly around the whole area - the hole on the underside, the botom of the tap (it can be lifted up a bit) and between the tap base and sink top, etc - and apply a layer of Polyurethane Gorilla Glue.

A thin smear on the WHOLE bottom of the tap base where it sits on the sink, a decent bead around the hole on the underside, and a thin layer on the remaining top of the plastic nut. Do it up firmly, wipe away every trace of excess from around the tap base on the top of the sink (tho' you can trim hardened stuff off the next day if any appears) and then wrap a strip of paper towel around the visible part of the threaded tap spigot and flexi connector to stop any of the glue dripping on to it. Leave it overnight.

The stuff is gap-filling - ie it foams up... I think it should do the trick, and it certainly won't make it worse. If a plumber is required later, it shouldn't affect him - he can break the nut to remove the tap, and any glue residue should be easy to trim off.

But, it's a 'bodge' :-)
