Metal will pick up heat but not the pcv pipe.

What did you use to mark the PVC?

KISS.

Mark your plastic spoon with a Sharpie. It works. I've done it on two spoons. Dry off the area of the spoon before you mark it. If you want to get really complicated, you can buy the Sharpie multi-color pack and color code each gallon line...

Also, you may want to do the following:
If you know how much water is typically left behind in your brewpot, use that as your 0 gallon point.
If you leave your IC in your pot the entire time, mark the spoon with your IC in the pot.
If you don't have your IC in the pot, either mark a separate spoon with the different lines or use dotted lines on the same spoon. Now you'll always know how much water/wort is in there.

Finally, if you have a slightly curved bottom (keggle) measure from the same bottom point all the time.

Another finally, make a backup--get a piece of wood or whatever and transfer your heights "just-in-case".

I use a Sharpie also. The ink fades after about 20 batches so I have to redo it every years or so.

I didnt even that about the chiller and I'm sure I would have on my first brew day with the new kettle! Thanks again.

....print a sheet up and hang it in the garage....

I put a table with some key values on the back of my metal ruler. One table for my sparge tank and one for my boil kettle. Inches on the left, gallons on the right. For me, this works better than notches or marks because I make both 10 and 15 gallon batches on the same equipment.
