Review: Might save you a ton of money! - This little device has proven twice that it works very well. First time was a false alarm where a leak had come from another part of my plumbing. Second time, my RO system's waste tube has backed out of the drain, shooting water into the cabinet. System shut itself off promptly, no true damage to the cabinet and overall easy problem to fix! Very easy setup, have it settled between RO filter system and plumbing. Shuts off completely when open as in picture. So glad I thought to add this feature to my system! I use in conjunction with a WiFi leak sensor, so I knew I had a leak in the cabinet and was able to get back home quickly to investigate. Glad that all of these features exist, as it saved me from more headaches and definitely works well! ## Features - NO MORE LEAK CONCERN: Automatically shut off incoming water flow to a water system in the event a leak should occur.

I ran out and need more** A: On Amazon just look up b Valve and it should give you have some suggestions. **Q: Is there a part number for just the cotton? Not under B valve** A: It’s unfortunately under the leak protection Tg **Q: size of the pads (pills)?** A: 5/8 inch wide. Most (or all) of the compressed towel pellets you can find are 20mm (0.2 inches too big to use with this) so I'm buying a different leak detector shutoff that uses the 20mm towel pellets, since the only refills I can find for this are in a 3 pack and cost as much as buying another leak detector. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent.
