Where This Valve Works
The John Guest tank ball valve is engineered specifically for reverse osmosis storage tank installations where quick disconnection and reliable shutoff are essential. The push-fit design accepts tubing without clamps or threading, making tank swaps and system maintenance straightforward. Both PPSV500822W and PPSV501222W models feature the same polypropylene body and food-grade EPDM seals that meet NSF standards for potable water contact. The 1/4 turn operation provides positive shutoff when you need to isolate the tank for filter changes or system work. While designed for water, consult John Guest customer service if considering use with other potable liquids, as compatibility varies by chemical composition.
