PureSec 2 Way Kitchen Faucet Diverter Valve/Splitter with Female M22(≈22mm) Thread and 1/4 OD RO Tubing outlet for Counter water Filter

Water comes out fast through both the filtered side and the non-filtered side. Non-filtered side has a nice aerator. Only down side is forgetting to move the lever back to the non-filter side when done filtering. Last one we had for 5 years was the pull to switch over type and it had an internal spring that always went back to the non-filter side automatically. Unfortunately the internal o-ring jumped out of place when the pull was pushed in while filtering and not designed to be dismantled for o-ring service or replacement and not available on Amazon. I highly prefer the use of a diverter valve to direct water to a filter because it does not constantly leave the filter under high pressure. Many of the 1 star water filter reviews mention that their filter exploded or came apart and caused major water damage in the home. It happens with all of the manufacturers. My current filter set up is through a Dupont Quick Twist 1 Stage Drinking Water Filtration System Filter WFQT135009X and from the filter tubing adapted 3/8" outside diameter clear hoses to connect to this diverter valve. Unfortunately the local hardware store no longer carry the Dupont 3000QT replacement filter but they do carry the Culligan RC-EZ-1 which works if the cartridge is slightly modified. The Culligan is missing a slot. Some use a dremel but I used a knife that was heated over a flame to cut away the plastic to create the missing slot. Not for the faint of heart but it works great.

Good product.

It looks like all the other diverters, but works better than others I've had. It has a good black elastomer gasket at the top faucet fitting. The swivel works nicely and is leak-free. Same with the valve lever -- it's firm yet smooth; again, no leaks. The 1/4" inlet/outlet fittings hold nicely. The aerator works well. I've had a few of these for under-sink RO systems for many years, and this one seems the best.

Works great and keeps the sink functional. Helps keep the RO lines tidy

The product made of high quality material’s recommended

Bueno

I first realized that the water flow/pressure didn't seem to be as good as with the diverter that came with the filter system I've been using since 2017. Then, after about two months of use, the lever became loose and difficult to position correctly for getting filtered water to flow. I purchased this diverter because of the all-metal construction, thinking that it would hold up better than ones with a plastic lever. After the lever became loose, I installed a diverter with a plastic lever that I had purchased several years ago but had never used, and the flow/pressure for both filtered and non-filtered water is great again. Conclusion? There is something wrong with the design and construction of this diverter and I cannot recommend it, due to the flow/pressure issues and the lever not holding up well.

Functionally it’s probably as good as any other model. Quick connection and no leaks. It makes dispensing filtered water from a counter top unit convenient. Looks okay.

Works good

Works as expected with my water filter. Easy to install. It came with all necessary accessories to prevent water leaks, and they were useful.

Totally happy. Works great for diverting water to my RO filter system.
