Putting Back Together a 1" WATTS 009M2

Описание к видео Putting Back Together a 1" WATTS 009M2

My personal Favorite Backflow Preventers to work on. The Watts 009M2. This video illustrates the insides of a 009M2 Backflow preventer. I took apart the backflow preventer because it failed its annual test for a number two check leak and to show you the individual pieces that prevent backflow incidents.
