Lost pressure control switch

I think this is the solution to all problems come the first service at AS, already discussed with them as a possibility but now I know there is work to be done anyway.
The storage in this area is already compromised by the pipework and the need to keep the vent clear for air flow and removable for adjustments of the pressure switch so the Shurflow wont be much worse.

I agree Marconi. The basic arrangements only seem to change infrequently. My Bourton is the same layout as a Broadway but positioning of stuff under the RHS bench seat is different. We have an electric box under the seat which if I recall correctly is in the back of the wardrobe in the Broadway. Our pressure switch and Truma drainage switch are reached trough holes in the box but are fully exposed in the Broadway. I expect that a Nuevo has the same layout under the seat as a Broadway and a Stanway as a Bourton so that is 4 arrangements that could be standardised.

We have a  fresh water tank under the seat as well - needed becuse a big enough tank can't be accomodated underneath the Mercedes chassis because of the rear wheel drive - but why do they have to stick it away from the end and sides leaving small useless areas. The exposed pipework could also be more tidily arranged.

Still off topic, we wandered into standardisation of layout in the same models.

I was busy making a pattern or template for arm rest covers for the Puegeot front seats this morning so that my wife can sow up some covers to protect from scuffing.
It made me think, do people consider that every time the company that do an excellent job of the AS upholstery get another seat to do they give an upholsterer or unskilled botcher a length of cloth and say 'make a cover for that will you'. I strongly suspect that they have a set of patterns and standard methods and procedures for producing such a good job. The fit is so good that each seat grins in the same way around the corners.
How much more important it is to do the plumbing correctly so that the frost control performs its intended protection of the boiler.
