What do the settings on the head mean? I can see I can twist the cap but what setting should it be set to?

On my system, there is a separate small meter which registers the amount of filtered water left. After replacing the filter it gets reset to 600 so I do not have to do anything with the filter head. As far as I can see from looking at my filter head, there are just numbers 1, 2 and 3 which refer to the bits that connect to it. No settings involved. Sorry not to be more help.

can you change the filter head yourself?

You can depending on your DIY skills! I got my plumber to fit ours. Quite straight forward.

Can you use this with any Grohe kitchen tap?

Yes that’s why I bought it. It replaces the old style filter heads but pipe work is compatible.

what is the external thread size? 1/2 or 3/8?

The external thread size is identical to to thread size of the water filter cartridge which it srews on to. Unfortunately I am unable to quote wether it is 1/2 or 3/8 ".

This was a new head for my existing system

Despues de 5 años he cambiado el cabezal del filtro, no tuve que destornillar la sujeción, se puede encajar la pieza móvil en la anterior sujeción, resulto más fácil de lo esperado. Y ahora otros 5 años de agua filtrada, cambiando el cartucho cada año.

Qualité Grohe, rien à redire.

Ho installato il filtro acqua Grohe con il suo supporto e devo dire che è stata una delle migliori scelte per migliorare la qualità dell’acqua in casa. L’installazione è stata relativamente semplice e veloce, grazie al design ben studiato del prodotto. La differenza rispetto all’acqua del rubinetto è incredibile! Il filtro elimina efficacemente cloro, microplastiche, pesticidi e metalli pesanti, dimezzando anche la presenza di calcare (ho effettuato il test che mi ha mostrato come il calcare sia passato da 21 a 10 gradi francesi di durezza) Inoltre, arricchisce l’acqua con magnesio e zinco, migliorandone sia il sapore che le proprietà benefiche. Ora posso finalmente bere direttamente dal nuovo rubinetto (a tre vie che ho installato) senza dover acquistare bottiglie di plastica, risparmiando e riducendo l’impatto ambientale. Il rapporto qualità-prezzo è ottimo e il risultato finale è un’acqua pura, leggera e dal gusto decisamente migliore. Se state cercando un sistema di filtrazione affidabile e di qualità, questo è il prodotto giusto.
