Rubinetto per filtro acqua - Rubinetto a collo alto

Perfict addition to the water filter supplied.

Tap started to leak in its third year so have just spent a couple of hours in a cramped , damp cupboard under my sink fitting this replacement. Seized up of course so had to cut it out.
To be up to standard for general use I would suggest EM upgrade their tap to give a ten year life span as with normal sink taps.

This was not what I thought I was ordering so am returning it as it is not what I was wanting. I am sure the tap is fine but not right for where I want it

I need to rep[lace an existing faucet with this new one. I need instructions, particularly regarding removal of push fit connector from existing faucet and installation into new faucet.
