I had some Polyairs installed less than 6 months ago. Today I am taking the vehicle back to the installer for the second time as the hose has come off the same side twice. Has anyone had similar problems? Is their something I may recommend to the installer to minimize such recurrences?

Hi
Ross,
I also run Polyairs without any problems.
I don't think the problem will be with pressures, it will almost certainly be that there isn't enough slack in the airline to compensate for articulation, or alternatively
check and see if the line runs past anything that can foul it, whether flung up from underneath or part of the undercarriage.
A good way to ensure that your airlines are not stretched or fouled is to piggy-back them to the brake lines - use plenty of slack and then put the airline in corrugate. I then zip tie them to the tips of the brake lines.
I would also recommend using new push on fittings now as they might be loose after coming on and off a few times.
Good luck with it and persevere with the Polyairs - they are a good bit of kit.

The hoses are a little on the dainty side. I am a little paranoid of a
rock severing one. Have considered replacing them with heavy rubber or perhaps a braided hose.
What sort of vehicle are they fitted to and where are the valves mounted?
Perhaps there is too much strain on the hose. I like pocking around after a job like that has been done to my Prado to ensure every thing looks Koshur. When
mine were fitted I had to get under the car with extra cable ties to ensure the hoses weren't hanging down too much and exposed to possble
rock damage.
Fitters usually just do the bare minimum to get you out the door.
Had to take
mine back to ARB in Osbourne Park a couple of times for jobs they had to rush due to overbooking. Once I time a took it back (squeeking
snorkel) the other they came out to my place at Swanbourne (second battery tripping fuses) to fix the problem.
Had an Anderson Plug fitted once and watched the guy like a hawk, to find he was trying to earth it to the tow bar!
Have a look if it looks suspect get them to fix it before it fails in the middle of no where.

Hi
Ross,
Inherited polyairs with my car. Only problem I had was couldnt inflate/deflate one side. Turned out it had a kink in the line which was fixed by opp lock bunbury free of charge. Sounds like the line needs to be a bit longer and fixed so that it doesnt pull out. As for concerns about the line being danaged by rocks, run it through another tube for protection, alternatively lagg it up.
Mine works
well, especially towing and with the long range fuel tank, just firm things up around the rear end. (Always liked a firm rear end!).
Good luck.
