How to extend drain pipe for Zip Boiling Hot Water Tap?

[BenjiCharlie]

I have this drain pipe for a Zip Water Tap Font/Drain, but it's only 1000mm, it needs to be ever so slightly longer to then attach to the waste pipe under the sink. Is there a heat resistant waste pipe available or some sort of attachment/extender? It might only need to be 50-100mm

Hi @BenjiCharlie,

A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Unfortunately, standard vinyl tubing and plumbing connections are not able to be used to carry large amounts of boiling water, and I'm not aware of a suitable high-temp tubing or extension that you could use.

I'd suggest giving the tap's manufacturer a ring. I'm sure they'd be able to point you in the right direction to ensure everything is up to standard and you are covered by any warranty that they offer.

They may say that they are happy for you to use standard vinyl tubing as you wouldn't typically be pouring large amounts of boiling water straight down the drain, but you should certainly check first.

Let me know if you have any further questions.
