How to tighten a tap mixer?

[junjcueto]

 Just first time I see this kind of undersink tap mixer fitting. 

Thanks

Well, my eyes are rubbish - but to me, it looks like that 'black' thing is a horizontal holding platform.

Insert the mixer.

That bracket slides up the hoses - wriggling the mixer for best fit - then you slide it across - so that it latches and holds it in place.

The installer now has his/her hands free to reach for nuts, washers and a long socket.

Fit the nuts on the threaded rods - tighten

I was thinking the nuts maybe were never fitted - hence the mixer is loose?

All theory of course - from a layman.

Another thought.

Get a better resolution photo.

Take it to a dedicated plumbing supplier store - show them.

Hi @junjcueto,

Late to arrive (as usual) and I see there is a group of eyeballs checking out the mixer thing.

Not sure... maybe with assistance get someone to push down on top of the mixer while you squeeze those vertical pins with a multigrips.

Cheers

Hi Everyone, 

Sorry for the late reply, appreciate all your help unfortunately, I can't honestly figure this one. Might consult a plumber for this.

Hello @junjcueto 

I'm so sorry we can't provide you with more information about your tap but suffice to say it has a unique fixing system. Perhaps a plumber will be able to figure out how its fixing system operates.

If you need further assistance, please let us know.
