Wunda only provides pipe which is 100% leak proof. By using a 5 layered pipe comprised of an EVOH barrier to prevent oxygen ingress and rusting the aluminium core as well as Pert for superior flexibility.
We also pressurise the pipe at the point of manufacture, so you know instantly before putting it in the floor whether the product’s been compromised in transit.
Since 2006 we’ve never had a leak. Ever.
