As anyone any advise on changing the waste and fresh water pipes from the underslung tanks?
A couple of weeks ago the waste pipe split and was replaced.
Returning from a a weelend away this week the fresh water pipe split very close to the tank when I went to drain down.
It appears that the flexible pipes fitted by aurosleeper are going brittle in the first winter with a new van and as I now have to crawl under the van to replace it I would like to know if there is better piping material that will be flexible and not fracture in cold weather.
If this had split during use it would mean no onboard water.
