I’m not a plumber nor do I understand what this thingie is… I ordered it per instructions from my hubby. It arrived pronto so began 3 trips to Lowe’s all in the same day, a lot of profanity issuing from the area where it was being installed, a small fire from a failed weld attempt, a lot of DIY You Tube videos, one final trip to Lowe’s and our pool water leveler was back to doing whatever it’d been doing before! I’m just the person ordering whatever these kind of projects require with no understanding of what that product actually is… keeps peace around the house… sort of!
