So ... I am now at the point where I have a more or less empty van, rather than a campervan. I'd like to redo the gas pipes, partly because I want to get the fridge plumbed in, but mainly because it's not up to spec anyway (sole gas pipe to the stove wasn't even secured to the body, and gas bottle just flapped around the back... It has a screwed in strap but almost all of the screws had pulled out, and that's after I'd rescrewed it in and doubled up the number of screws).
Gas plumbing. I've done water plumbing with compression fittings. It can't be that much harder, no? I find references to 'gas tape' which I guess is something similar to PTFE tape, in that it's some kind of sealing tape? You get leak detector aerosols to find out if it's leaking or if you have big balls and are sure there are no major leaks you can use a lighter (eek! But I have seen it done ). I'd rather go for the aerosols
As I understand it, you should fit the cylinder in a locker (ideally only accessible from the outside, but as I have rear doors I'll probably make it face the rear doors, simpler to do). It should be made of metal and airtight, with a vent in the floor. No flex fittings except from regulator to the piping. LP side should flow into a manifold with separate shutoffs to each appliance. Optionally a shutoff should be fitted next to the appliances. All piping apart from the flex hose should be secured to the bodywork. And, there has to be one (and ideally two) gas outlets under the fridge just in case it leaks.
Anything else I should consider?
