I have the same problem, It is easy to remove the mixer block as previously stated.
Big problem is getting a replacement mixer bloc.
I am in Australia. The mixer block has
K 35 B
Made in Austria
for LA TORRE
written on it.
Where can I get a replacement from?
The problem is that the white plastic under the 2 small orings is undercu on the side in 2 places. This has caused the edge to crack away from the main part and not support a small part of the oring- leading to a continuous dribble/leak through the tap spout.
Only 1 side of mine has cracked, however you can see hairline cracks in the otherside, so it appears to me to be a design fault.
Where can I get a replacement?
