Seems insane. Is there some non-mold flex tubing available anywhere
such as Home Depot?

Run cleaner water or sanitize the tubing periodically.* Tubing is just
providing a place for mold to grow.* The spores are in the water.



I think gfretwell has the answer

Maybe you need food grade tubing? Just a WAG.

Would not mean it is mold proof. I see mention of silicone and vinyl
tubing in food grades that still get mold.

I defer to you. I am certainly no expert in that. WAG...


I'm not an expert either but did do a couple of years of R&D on plastics
for food contact but mold issue never came up. I would suspect that if
a chemical were added to the plastic to retard mold formation it would
not be allowed for food contact.

You are right. News flash! Don't drink my Kool-Aid.
