Caravan DIY: Water filter install

Tim's been meaning to fit an under-sink water filter since we started the trip, and he finally got stuck into it. The logic is simple: we already filter the water going into the tanks, so putting a second filter on the kitchen tap means the drinking water gets filtered twice. Everything else — shower, hand basin, the tap on the A-frame — stays unfiltered, because there's no point running all that water through a filter you're not drinking from.

A few things made this install easier than expected:

The filter he chose has a slightly higher flow rate than units like the pure taps, so you're not standing there forever waiting for a pot to fill.
It came with 12mm John Guest fittings — the same standard already on our van — so no converters, no mucking around with different hose sizes.
He found it on Marketplace, still in the box, never used. Someone bought it with good intentions and never got around to fitting it.

Before cutting into anything, he purged all the water lines first, pulled the cabinet doors off for better access, and put a towel and a pot underneath to catch whatever was left in the hoses. Tight workspace, but manageable.

Have you fitted a water filter in your van? Under-sink, inline, or something else — what did you go with and would you do it the same way again?
