Flex-PVC Tube for Water Sample?

Hi,

I have purchased a second hand KDH and therefore will be using newly purchased tubing for the setup.

In the online guide for the KHD setup it details the below reference to Silicone Tubing for the Water Sample and Waste Lines, however is it OK to use Flex-PVC Tubing for the Water Sample and Waste Water lines?

Thank you in advance.

I opened a support ticket as needed a quick reply and was advised you can use Flex-PVC for all :)

Yes, you can use Flex-PVC for all 3 pump heads.
