Quick how to below:
- remove sink unit and bowl (4x Allen screws under the sink and use a scalpel to cut mastic. Bowl 4 more Allen screws)
- completely remove the tap (you'll need a plumber's spanner shown in the picture below)
- note the tap tails will not push back in because they are secured by a stainless steel location pin (shown in pictures below) which locates a collar on the nylon tail connector. You'll need to access both sides of the tap to remove the pin. Hence having to remove the tap
- remove stainless location pin which is an easy push fit (use a 3mm Allen key or similar)
- push the nylon tail connector back in (a bit of silicon grease will help but it's an easy push fit). Push the location pin back in
- make sure all 3 pipes are secured correctly
- reassemble and enjoy your non leaking van.
Anyway I hope this helps.
It's a bit of a faff but definitely doable if you take your time don't try a force things.
