Protect yourself from this toxic water filter I ordered this protect in order to protect myself and my family from any toxins that might be in our tap water. Imagine how upset I am to know that, having spent a considerable sum on a filter, it contains the toxin 1,3 Butadiene, known to cause cancer and birth defects. How can I forgive myself for using this filter for my grandchildren's water? I formally ask Watts Premier to stop using this in a filter, to widely publicize what they have done, and to refund the money of those of us who have used it. Do not purchase this product!! 1Amazon, please Do something about this vendor's support. Customer support is very poor.Called them and waited for a suppor person on line for a long time, but no one answersI have leaky faucet and loud noise form the drain.Followed their troubleshooting directios,but it did not fixed.It seems the faucet is physically faulty.Replacement part is needed. 1Leaky faucets These always worked great and I've purchased over 10 of them for remodel projects. Unfortunately the last two I got had leaky faucets. I even ordered 2 replacement faucets and they leaked too. I can no longer refer this product or count on the faucets to work properly. Shame, it's the only problem I have but its a biggy. 1worked fine for first 6 months Like other reviewers here, I am having some issues with this system. This is my 2nd system (1st system was fine) and after the first 6 months, the 2nd's unit's faucet has sprung a leak every time we use it. The general contractor had his plumber install the system (we did a complete kitchen remodel) so we thought, okay - maybe the plumber didn't do it right. We hired another licensed master plumber to double check this week. He came in, took his time and looked through everything and said everything is perfectly installed. He believes the unit (faucet) itself has gone bad and asked me to call for warranty service.Here is where watts gets the 1 star. I have called every day for the last week and every time, I have been ON HOLD for more than 1 hr. EVERY single time. As a matter of fact, I am on hold as I am typing this review. I have left messages for the operator for their technical/warranty/order dept to call - no go either. At this point, we will probably just rip the entire system out and replace it with another brand.Time is money and after being on the phone for 5 hr+ on hold, just not worth my time. Buyer beware. 1Nice system - add a permeate pump - and check your water! I've tried many different types of RO systems, and this one is my favorite in the manifold category.Positives:* The automatic shutoff valve (ASV) is not encapsulated in the manifold, which means it can be eliminated when using a permeate pump.* quick change filters are convenient.* the way the manifold is constructed, the "tank" port is actually a tee fitting between the output of stage 3 and the input of stage 4. The allows the stage 3 permeate to be stored in the tank, and with a couple of extra fittings, the tank water can be run through stage 4 when the faucet is turned on. With many other manifold systems, this is not an option.Negatives:* the drain saddle is a bit finicky - if the saddle rotates slightly (which it will do if bumped, even when tightened) the drain will be a bit noisy. to solve this problem - order the watts 164014 drain adapter and eliminate the saddle. This issue can also cause brine leakage at the base of the faucet.* the fitting on the tank is 1/4" - I prefer 3/8" for better flow to the faucet.* the membrane is not high-flowing, and even with a permeate pump, it can take some time to fill the tank during the winter. In Arizona, our tap water temperature varies greatly with the seasons. The production rate of this unit doubles during the summer.On this install, I used the Aquatec ERP-500, which is a "quiet pump" that doesn't click, I might switch it our for the Watts unit, as the noise doesn't bother me, and I think the Watts is more efficient.Since a permeate pump is effectively a check valve - if you want to use the post filter instead of storing stage 4 water in the tank, you need two T fittings and a bit of extra tubing to create a bypass. Diagram below.With the faucet output from the manifold, I elected to install an alkaline filter before plumbing to the faucet, which was a nice addition in terms of taste.Overall, a good system - just pay attention to the details when you plumb it.As a side note - I've seen many reviews referring to clogging in the stage 1 & 2 filters. It is important to remember that there is a not a "one-size fits all" filtration system. Get your water tested (especially well water) and figure out what you need prior to the RO. In my case, a whole-house sediment filter was required to get the RO system to perform as designed. 4Great System that Replaced My Existing Culligan Since moving into my house, I relied upon a custom installed Culligan 3 stage reverse osmosis filtration system (under the sink). Every year I paid a service rep to come to the house and replace filters and service the system. Costs ranged anywhere from $125 TO $175 including parts. (As a side note, in the 8 years Culligan serviced my system, they never cleaned the tank.) This year I called for service and was told the cost would be over $250 in parts and labor to replace the 3 filters and membrane. I had enough at this point and looked for a cost effective (and updated) alternative solution. Culligan also offered to lease me a system for over $300 a year that included servicing. I said no.After much research, I decided on this Watts Premier. I will not bother detailing specification comparisons because those are readily available on the Internet and all these systems essentially provide same filter performance. Since my plumbing was already setup for this system by Culligan, I figured no big deal in switching out. More on that later. Anyway, the product arrived and I was not dissapointed. The product was packed very well with no missing items. The system is comprised of quality components all around. The tank was actually better made and larger than my Culligan tank (8 years old). The filter components are made of quality material and far easier to replace than those on my Culligan system. The supplied quick connectors worked great. Everything is color coded and instructions are OK, though a little more detail would be warranted. The faucet provided is actually better quality than my Culligan faucet and has a filter replacement indicator light. Note that the faucet is Chrome. I did not mind even though all the faucet hardware is Nickel- but some may mind.Installation was fairly simple. As I said, I was replacing a Culligan system (allow more time if you are not replacing an existing plumbed system). So, I did not need to drill through my granite to install the faucet (I would get a pro to do that). The existing hole was a little small, but I managed to make it work. My drain pipe and cold water feed was already plumbed as well as my inline to the refrigerator water supply. The main issue I ran into was tubing diameter. Culligan used 3/8" whereas Watts uses 1/4". The 1/4" seems to be the new standard and I actually noticed increased water pressure post-filter compared to the Culligan system. But, because of the difference in diameter, I had to change out some quick connector connections. This is where I would dock 1/2 star from my rating if I could. It turns out Watts does not include a Tee Quick Connector for connecting the system to the refigerator water supply. I am sure Watts did not include it because they figured you already had one or did not want one. In my case however, I had to transition from 3/8" to 1/4". I ended up ordering the part (Celcon Push-to-Connect Tube Fitting, Acetal Copolymer, Tee, Tube OD) from Amazon for about $4 cheaper (free shipping) than my local Home Depot, which did not have any in stock anyway (they wanted me to buy an entire kit).PRIOR TO INSTALLATION I recommend you read the instructions carefully, gather needed tools, and layout all the parts. There are not so many parts that you will find installation overwhelming. In fact, I was left wondering why I had not done this before since it would be cheaper for me to replace the entire system every year instead of having personal service. Installation time to replace exisyting system is about 45 minutes. Without existing system, I would plan for 2 hours.AFTER INSTALLATION be sure to check for leaks after youu turn water on. Check regularly for a few days. I could not detect any leaks with the Watts. Post installation, the Watts requires you flush the system 4 times prior to consuming water from the system. This will take place over a 24 hr period. You simply let the system fill the holding tank and then drain entirely (emphasis added). Repeat 3 more times. I suspect those reviewers complaining of a "plastic" taste upon first use are not performing this step 4 times and/or accurately. Remember, you need to completely drain the system (empty the tank). The first few glasses of water appeared "milky white." This is due to air in the system and is normal. The water is fine (if you let the glass sit for a minute or two, it becomes crystal clear). It went away after two days.SPECIAL NOTES: If you detect leaking from any quick connections, chances are you did not insert tubing far enough. Simply try to push tubing in further- don't be gentle. The noise you hear in the drain is normal during filtraion process. It can be a bit annoying. My Culligan never made this noise, but the Watts is a different design. This noise is the result from water that did not make it through the membrane filter and IS NORMAL for this design. 5Bad install kit I was hoping to do a quick swap with an older Watts Kwik-Change that had a blown regulator inside of it. The very first problem is that the RO system is NOT what the picture shows. There's a regulator and hoses sticking out of the left side. You'll must replace or swap the hoses between the regulator and the filter harness before being able to install on the left side of a cabinet. The second problem is that most RO systems use 3/8" OD hoses on the low pressure side. This uses 1/4" hoses everywhere so any existing RO plumbing must be replaced. Up next is the water intake adaptor, which is sized for the unreachable base of the faucet, rather than the water inlet on the wall. Finally, the drain hose uses a sketchy adaptor that clamps over a hole that you drill in your sink drain pipe, rather than the custom replacement pipe. Go buy the custom pipe because drilling a clean hole is going to take serious luck or skill. I ended up replacing almost the entire installation kit with about $40 of RO install parts from the hardware store.The system pressured fine without any leaks. If leaks are a problem, make sure that you never allow a quick-connect junction to lock onto a hose that is not fully inserted. The lock is sharp and it can damage the sealing surface at the tip of the hose. Cut the tip of the hose off if it binds while you're unplugging a hose.The waste water limiter on this kit, just a tiny bit of plastic screw, has a massive flow rate. It looked like the waste rate was over 5:1 relative to the clean water rate. The instructions show a long screw so this could be sloppy factory assembly. I swapped in an older limiter that's closer to 1:1. You can replace the black 3/8" OD drain hose with a clear vinyl hose so that you can see what it's doing.With the install kit totally replaced, it seems to be working well. The water is free of off-flavors and it's not leaving mineral residue in glasses. It's still using a lot of water by turning on too often; maybe every two glasses of water. 2Has some problems I choose to buy this model because it was almost identical the previous trouble free one I had for 6 years. This one however was a pain in the rear. The primary issue was the airgap in the drain system. It would not stop leaking no matter what we tried even with the suggestions from Watts customer service. I missed amazon s return date by a few days because my handyman kept thinking it was an installation error and wanted to fix it himself. I finally called someone who specializes in water filters and paid big bucks to have him look at it. He said it s a common issue and bypassed the airgap. The airgap is an extra layer of protection from drain water contaminating your pure water. It s a good idea, but this model needs some kinks worked out. Although I had been a satisfied Watts customer for years I d be hesitant to go with them again. I do want to give their customer service department credit for trying their very best to help though. 2I called Watt's customer service and the tech recommended this model as a replacement I was replacing a Watts system that was a number of years old in a house we just purchased. The old one had a failed ASO valve and a failed storage tank bladder probably due to excessive water pressure in the house. I called Watt's customer service and the tech recommended this model as a replacement. After removing the old system I had a lot of difficulty installing the new faucet. The old one had a nut that you tightened up to secure it in place. The new had a toggle bolt type was very difficult to tighten properly way up under a sink. After fighting with for an hour to get it tight and to get the tubes connected I turned the system on and it leaked out of the vent hole. Took it back out an hooked it up outside of the sink and could not resolve the leak. I wound up reusing the faucet from the old system and splicing the tube together. Also had trouble with the adapter to the cold water shutoff valve and had to reuse from the old system. A design issue is why does the brine tube have to to up to the faucet and then down to the waste pipe, makes the faucet area to crowded? Works fine, the water is much better than the unfiltered water. If I did not have the old system to source parts from this would have been a return. 3Cavalier Wholesale isnt an authorized Watts Dealer, Watts will not honor warranty Faucet started leaking, went to get warranty repair from Watts since it was under a year since I purchased it.. The customer service guy at Watts said that this was not a 531411 but rather a 531407 and per the serial number was manufactured in 2012 (i purchased from amazon Sept2016)He says the seller (Cavalier Wholesale) isnt an authorized dealer and I am SOL.Good news, I bought a second one for another project and used the faucet from it to fix the first one. Well I had a plumber do it.. But plumbers cost more than faucets so i guess i will be buying a 70$ replacement faucet now. Not sure if I am miffed at Watts about making leaky faucets, Cavalier for foisting old stuff like new, or Amazon for allowing Cavalier to do that. Little bit of each I suspect 5
