Kitchen Tap

They're usually held by a horse shoe shaped clamp secured via a long stud on the tap that passes through the worktop/sink. You'll need a deep socket (12mm or 13mm at a guess) a torch & a very flexible back to reach in under the worktop.

On my Bailey Ranger the fridge is under the sink so I was able to access the tap nut by removing the exterior top fridge vent cover.  Much easier than removing the sink!

Like the idea of accessing the tap by removing the exterior top fridge cover.... is this quite easy to do? can't see how to remove it?...any instructions? would be much appreciated!

Muso. On my 2009 Ranger it is simple and I would assume your Pegasus is similar.  Under the top part of the vent there are 2 black slides at either end.  Just slide them and ease the vent off, there is then a dust screen which just lifts out.  Replacement is the reverse!  The slides may be stiff if they have never been used; WD40 is you friend just spray on and leave for a couple of minutes.

Doesn't seem to be any slides on the vent,(I've attached a photo),or a horse shoe shaped clamp and long stud as Emilysdad suggested,so still struggling!     Someone suggested I should remove the sink? but not sure if that would work either...so back to the drawing board??

from about 4mins 40sec Dan slides the catch on the left up & then the whole thing comes out ... 🤔

ED has provided the answer for access.  My fridge is a Thetford hence the difference.  Good luck.

We have a very small leak around the base of kitchen tap. My immediate thought was access the tap base through the upper vent of the fridge but, alas, this won't work. There is an aluminium sheet between the fridge and the sink base with no obvious method of removing it.

The aluminium sheet is, I think, a heat shield.  It was held in place by a number of screws which were quite easy to remove - and re fit.  I had to use my 'bendy' screw driver though.  Once removed you can access the bottom of the tap.

Thanks, Commeyras, I'll go and have a closer look.
