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

The previous one sprung a leak, and I needed a replacement. This one looked solid, and once received feels like a good part. I hope it lasts and doesn't break. So far worked and no leaks.

Good product.

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

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.

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.

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.

I'm reviewing the 2-way Puresec kitchen faucet diverter. The included picture illustrates my old PUR diverter on the left with the Puresec model on the right. For those confused about the PUR diverter operation, the white tab is pulled out 1/8” to divert the water and pushed back in for normal operation. Notice the size differences, tubing locations, etc. Baseball is on TV so... Strike 1: This diverter is LONG. Measures 2-7/16” as delivered. This is not a good choice for the angled (low rise) kitchen faucets. However it may be suitable if you have a goose neck faucet – “maybe” (I'll get to the maybe later). I've been using a late 1990's PUR counter top diverter/hose assembly I saved when the filter housing started leaking and PUR stopped making the filters. It measures only 1-5/8” long using the original faucet aerator. I started looking for a replacement when I noticed occasional water drips from the PUR diverter. The length of this Puresec diverter just doesn't work for me and had the seller provided dimensions I might measured my sink/faucet and saved my money. I use a Megahome 1 gal water distiller daily and slipping it under the shorter PUR diverter has been no problem. The Puresec diverter makes getting the distiller under the faucet almost impossible. It's not as much the length of the diverter/handle as I can tilt the distiller w/o dumping out the water; but it's the very stiff 1/4” RO hoses coming straight out the back. The bottom hose is much lower now and has to deform upwards about a half inch (and the upper hose at least a little bit) which means positioning the distiller pot as close to the faucet pivot as possible. When the distiller pot is filled I notice the faucet is being deformed upwards at least 1/4-3/8” so it can sit flat in the sink. Just as annoying; I fill a used one gal distilled white vinegar jug on a daily basis to top off my birdbath. With the PUR I can swing the faucet to the side, position the jug underneath, turn on, and walk away for 40-50 secs while it fills. The lower height of the Puresec requires putting my fingers at the backside of the faucet to guide in the 30% or more water that doesn't want to go into the jug because it's now tilted too far over. Strike 2: The 6 o'clock position of the lever, which almost extends to the bottom of the diverter outlet is frequently catching on my 2 quart pitcher as well as the vinegar jug and distiller pot. If it was placed in the 12 o'clock position for non-diverted flow it would be completely out of the way. Given the typical height of the faucet above where the diverter or original aerator mounts, it would be protected and a much better location. During my brief use of this diverter I adjusted my routine by not swinging the lever down before removing the pitcher, etc. However I frequently forgot I hadn't reset the diverter and now get annoyed when I want to fill a pan and it's still set for diverting. Aggravating! Strike 3: This is a multiple part problem. First, you get the challenge of attaching the 1/4” water lines yourself. (My PUR diverter had them attached at factory). I strongly recommend soaking the ends of your water lines in some hot water (120-140F) for a few minutes first; BUT let the tubing cool after placed on the hose barbs and before you thread on the fittings. My tubing was soft enough when I tightened the fitting that it cut/split and I had to start again. I initially tried forcing on the cold tubing, except at one point my hands twisted/bent the tubing and it split radially. In addition, I inadvertently twisted the small joint between the diverter and the housing for the two barbs. I re-aligned it and feared I was going to have a leak there; but so far no leak. Also, the two barbs are actually threaded in fittings so don't make the mistake of twisting the tubing or the fittings counterclockwise. Next problem is the hose barbs are coming out perpendicular to the diverter. This approach is better suited for the low rise faucet design as you can route the tubing down the faucet neck. For goose neck faucets this places the 1/4” tubing straight out the back and really doesn't work if you want to route the tubing along the faucet neck. Defeats the advantage of the goose neck in my opinion. If you want to use a diverter with a goose neck faucet I'd rather see the barbs for the tubing parallel with the diverter (i.e., 90 degree fittings and offset on the barb housing). This would allow closely tying the tubing to the goose neck for routing. Finally, the 1/4” RO tubing these days is quite stiff which doesn't allow tight bends. I don't know what changed from 1990's with the PUR lines vs now; but I can bend the PUR tubing into very tight turns with no problem. In addition, the PUR lines came linked side by side so rather than fussing with two separate lines I have one common pair – much easier to work with. Given most of these diverter installations only need a 1 to 1.5 meter length of tubing to connect with your filter setup, I'd rather see a diverter sold with factory installed lines, preferably linked together and with more flexible tubing to ease use at the faucet. End result is I gave the Puresec (and models just like it) only 3 stars. I'm not happy with this design and sadly it's pretty much all I could find. I asked the “great” Google AI to find a diverter like the PUR. It directed me to several alternatives; but each one was pretty much like this design. I can't believe consumers don't have better options. Probably explains all the “pull out” goose neck faucets I found that won't support a diverter. However, I did get the diverter installed and didn't have any leaks (for the brief 2-3 days I used it) so it can function properly. The aerator that came with the Puresec worked well although I noticed more splatter from it. The poor design for my application means it gets only an average rating. I'll keep the diverter rather than return such a low priced item and maybe when/if my 30 year old faucet finally needs replacing with a goose neck model it may become useful. Aside from the design flaws, the diverter is about as well made as others I looked at so it should hold up well enough (if it doesn't get broken when fitting pots/pans underneath); but in my short time using it (I re-installed the PUR) the lever didn't instill confidence it would last and honestly the removable aerator that came with it certainly seems to me to be plastic rather than metal. Overall, I'm appalled I have a 30 year old compact and elegantly designed diverter that works better than anything I've been able to find so far.

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

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