Grohe Ambi Monobloc Kitchen tap

[Autarch]

Hi there. I'm trying to replace a leaky tap with a new Grohe Ambi monobloc.

The new tap came with flexi tails with a 12mm coupling but my pipework ends in a 15mm service valve so I need to modify something.

Ideally I would just like to change the flexis as the supplied ones are very long anyway. Problem is the nut to remove them is way up inside the tap body out of reach. Does this mean I will have to take the guts out of the tap to get at them or am I missing something here?

Many thanks.

I recall that the tap tails cannot be removed from these taps, so you will need to modify the 12mm connection and use a reducing fitting from 12mm-15mm.

I think the flexies are 3/8th

Yup, I've found a lot of Grohe have 3/8" fittings, typically european.

Is it a service valve or iso valve? Ideally you would have 2 iso valve's, a small piece of 15mm copper and then a 15mm compression to 3/8" male iron for the flexi to connect to.

Thanks for the replies. It's a bit ridiculous that the £5 tails can't be removed on a £150 tap. I wouldn't have bought it had I known.

The 15mm valves are iso's but space is limited so I might have to reduce in soldered copper and install new 3/8 valves to fit the flexis to.

Odd that straight threaded adaptors aren't supplied or available.

Thanks again for your help.

When you say straight threaded adapters?

Are you sure the threaded flexi is fixed though, have you tried to remove them? Just checked and Grohe quote for spare flexi's for that tap, so would assume they can be removed to be replaced so standard 15mm to M12 flexi tails may do the job.

Straight threaded adaptor would be 15mm female one and and 3/8 male or whatever the supplied flexis require to fit on the other side.

If the flexis come off it must mean taking the brass insides out of the tap as the flexi nuts are screwed into it and a good 50mm up inside the chrome tap body with no access.

There are two torx screws in the brass part which I assume would free the guts from the body but I am a bit loathe to take it apart when I don't know if it will be hard re-assemble

Oh I see.
Cant say I've ever seen one of them I'm afraid

There's you exploded view of the tap BTW

Thanks.

Item 7 on the drawing may be the tool I need to remove the flexis. I'm not sure what it is though.

 

[Madrab]

That's the chap, the dis-assembling tool but at £60 - £20 + £40 postage I am sure you will take another approach

I recall last time I fitted this tap, I could not identify a way to remove the tails, so in my situation it was much easier to fit a 3/8th-15mm coupler.
