What are some lesser known items or tricks in your profession that most people don’t know about?
For me one thing would be Thrift drain cleaner. I was having issues with my drains being clogged and nothing really worked, but looking around on forums and advice from plumbers lead me to Thrift and now my drains work great.
A note about drains: My drain guy advised me to stop as much material as possible from going into my drains so they don’t need cleaning.
So I’ve put “strainers” (traps?) on all my drains, don’t use my garbage disposal, etc. and have much less need for nasty drain chemicals or a drain guy. Ymmv.
Playing it safe will definitely work, but also there’s nothing wrong with using your sink disposal properly. Nothing hard or firm like bones or plastic, no coffee grounds, and don’t drain fat in the sink.
