### ⭐⭐⭐⭐⭐ I feel good about getting brass over plastic.
*by C***Y on November 14, 2025*

Feels like it’s very solid construction. Easy to install. Used Teflon tape on the installation and have some very slight leakage. I mean very slight. I’m going to get some pipe dope and reassemble and see if that stops it completely from dripping. Happy I went with brass to replace the plastic one that failed.
