nut size on kitchen monobloc tap

[mjt]

hi

I have been asked to change a kitchen tap which is attached by a brass back nut on the body of the tap rather than than the threaded bar with the 10mm (or similar) nut.

Does anyone know what size nut is and are they standard - would a 3/4" tap back nut box spanner fit or is the nut larger?

I would measure it myself but i am not going to the house till Tuesday.

thanks

kitchen taps are usually 1/2" same as basin taps. usually only bath taps that are 3/4".

Monoblock taps are larger. Probably bigger than 1"

I think they're all different sizes, I think Steve has missed your issue.

I sometimes take the spout off of the tap and twist it, this sometimes loosens it so you can do it by hand. I've also got a few box spanners that help

yeah i have various box spanners but not one that is as big as a body of a monobloc tap - took one off a basin mixer a while ago and it was slightly larger than the 3/4" option omy tap back nut box spanner. i was able to reove tge basin and take it off with an adjustable spanner - not sure takng the kitchen sink off is really an option here!!!!

i was just hoping to have the right size socket to do it tahts all

my bad i misread the post lol. will be bigger as tipintim said. try giving it a twist anti-clockwise as secret squirrel said it may loosen the nut enough to undo it by hand.

Hopefully, if you can get a tiny turn at it, then it will turn off by hand. I get small footprints or claw type spanner ( like the monument type ) to loosen them.

Can be 1" or even 11/4" depending on the tap. If the threads are stiff and covered with puttty etc, you can loosen the tap enough to lift it slightly, then you can cut the tap off from above with a hacksaw blade.

Just measured mine for you. It looks to be 1 1/4"

This works (usually). Other option is to disconnect both pipe's, remove sink and get your grips on it. Extra work but gets the job done.

At times you have to be resourceful even if it means hard work. Personally I get my apprentice to hold the tap and zap it with a grinder, but a hacksaw blade works just fine!
