My plumber neighbor in Denver said using Teflon tape on plastic threads is a waste of time
He argued the sealant paste is better because it lubricates and fills gaps, which changed my mind after a stubborn leak on my sprinkler system. Anyone have a go-to brand for that paste?

Your neighbor's right about paste being better for plastic... but Teflon tape isn't a total waste. You just have to use the right kind. The white tape can stress plastic threads and cause cracks. The pink or blue tape labeled for water lines is a softer PTFE and works fine as a lubricant.

That bit about the pink tape being softer is interesting. I used the white stuff on a garden hose spigot last year and it split the plastic elbow after one winter. Had to replace the whole bib, what a pain.
