When to replace tubing

[celwin]

how often do you guys replace your tubing? I have some Primoflex tubing since 2010. Nothing wrong with it. Running distilled water and silver coil. Just wondering if there is an interval you must replace tubing with new ones?

Never, unless it's stained from dye or you want a different size/color/etc.

Yep, agreed. No need otherwise. The only "replacing" I do is when I clean out the loop, I might cut off the end of hose that was over a barb, if it's expanded a bit.

The inside of my Feser black tubing is completely coated in white, which I'm guessing is plasticizer leeching, is there any reason to change solid color tubing due to plasticizer leeching? or just ignore it?

I noticed some white coating on the inside of my tubing when I was cleaning up my rig last week, but it hasn't made a difference as far as I can tell.
