Clear tubing that stays clear?

I've a condensate pump in the crawlspace that I replaced the tubing on in June 2016.

Under there today, and noticed the clear tubing (on the left) is now opaque (on the right) to the point that I can't see if there is water in it or not.

I'd expect the tubing that sticks out the side of the house and is exposed to UV to change color a bit, but I don't understand why it is happening in a dark crawlspace.

Anybody have any recommendations on tubing that goes on clear and stays clear?

Regards,
leaning

Clear tubing discolors on the inside from the presence of the water.
I think all pvc tubing does that eventually.

PJmax,

Thanks. Do you have any experience with clear polyurethane tubing which contains no PVC? Does it stay clear?

I think any water will leave deposits in the inner surface of the tubing. A lot depends on the water hardness. Take a medium hard brush and try cleaning the tube end. I bet it comes clean.

No..... I haven't observed polyurethane tubing to see if it stays clear.
