When the installer fitted my floor standing boiler, he neatly, clipped the main 22mm feed to the wall. The pipe in question enter the room at floor level and has several components (pressure reducer, pressure relief valve, manual fill valve) inserted (compression fittings) into its run. At the top of the run, the feed pipe is bent through 90-degrees, with another non-return valve, before coupling to the boiler. The overall run is probably close to 2.5 metres and is clipped in 6-places.
I now need to replace one of the inline components, and it looks like I will need to disassemble from the boiler backwards to get enough play in the pipework to remove the component.
Is this just a 'fact of life/suck it up' situation, or is there any coupling or technique that I can use when I re-assemble to make life easier in the future - something like a sliding coupling along the lines of a trombone slide maybe?
