Frizzlife Leak Protection Valve For Reverse Osmosis And Under Sink Water Filter System MP99 & SP99 - Automatic Shut Off Protection When Water Leaks

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!

Easy to install and a very simple and straightforward mechanism for shutting off the water in the event of a leak. Could save a lot of money in prevention of water damage. I haven't been able to test it fully because I haven't had a leak but I like the simplicity of it and feel somewhat assured that it will work when needed.

This is an awesome mechanical shut-off valve; compatible with 1/4" RO line. It can be refilled with 'compressed towel tablets' - I purchased a hundred pack for cheap. It comes with 3 of them in the box. I have 2 of these units. One before my RO unit, and one at my storage vat. The fact that all of potential for flooding has been eliminated to just the "in" connections to these shut off valves brings me great peace of mind - and for a very fair price! Well worth the investment.

It’s a good device, but, it was shipped without the two clips the hold the water lines in place. If you are doing a replacement you can use the old clips, but, if you are doing a new install, you won’t be able to complete the job without first obtaining some clips.

This review is for Frizzlife Leak Protection Valve For Reverse Osmosis And Under Sink Water Filter System MP99. Last time my RO system leaked in the middle of the night we ended up with thousands of dollars of damage to our kitchen and garage. By the time our cat woke me up, because she couldn't get to her dish, water was well into the living room . I replaced the RO under warranty and installed this shut off valve, and an alarm. Day before yesterday, I came home to chirping sound I could not place. It turned out the my new replacement water softener started leaking while I was out. The valve did it's job, and the chirping alarm (a separate item not related to this review) let me know there was a problem. This product would have more utility if instead of the double sided tape, that didn't stick to anything for more than a couple of minutes, it came with suitable wood screw and nuts and bolts for mounting. I could be mistaken, but I seem to remember the product picture showing 2 wood screws as a part of the kit. Mine didn't come with any. I have no association with this product or its seller. I have paid for it out of my own pocket. I highly recommend this product. It is a 10 star out of 5 based on my experience. Next time I install any water system, nothing will be connected to water unless I already have this shut off installed. This should be supplied with all water conditioning systems.

Maybe I received a defective unit, but if you do or have purchased this leak stop valve, make ABSOLUTELY sure that you test it prior to trusting/depending on it. When testing prior to installation, the one I received reduced water flow, but DID NOT STOP FLOW.

Bought a cheap RO system for Prime Day and it blew several fittings over the course of installing two units (the first and a replacement). Needless to say I don't fully trust that the unit won't leak or, worse, blow another fitting and spray water everywhere while we're not home. I decided to get this as some cheap insurance. I'm really impressed with it. It installs easily, is very simple, and definitely works. I found that you can use the very inexpensive compressed disposable towels, often called coin or tablet towels, to do the same job as the ridiculously overpriced cotton refill tablets you see elsewhere on Amazon. Because of this, I was able to successfully test it with some actual water poured into the bottom of the cabinet under the sink without worrying about wasting the tablets that came with it.

What a geat idea. Just finished rebuilding a cabinet floor due to a leak so this is a wonderful tool. I did make a mistake and ordered this one with the wrong fitting size so had to send back.

Excellent produit. Facile à installer. Identique à la description et aux photos du produit. Très satisfait.
