Watts Premier 270156 12-GPM 1-Inch 110-Volt UV Disinfection System

Installed without a hitch (yup, actually read the instructions). No leaks. Per the documentation, the green light on the power supply supposedly tells me the UV lamp is working as expected. I chose to mount the unit horizontally and with the inlet and outlet ports facing down. Since I'm connecting to PVC, I included a drain valve on both sides, so when I replace the lamp and clean the quartz sleeve, I won't dump water on the floor.I do not really suspect my well water is microbiologically foul. But this seems to be reasonable insurance. This UV lamp replaces a sodium hypochlorite (bleach) injection system I had in place for several years. However, I already appreciate that I no longer have to work with a hazardous chemical.

The bulb was broken upon receipt and this was not discovered until after the return date. The crystal was very fragile and you must turn it very carefully by hand until it no longer leaks, or it will break. I called Watts and they considered it a shipping issue and referred me back to Amazon. I chatted online with an Amazon rep and she shipped us an entire replacement unit because there are no dealers locally. We ended up paying more for the return shipping, but their willingness to work with us after we missed the return date was worth it. The unit works well and cost significantly less than what was available to us in Hawaii. The 5 stars is because of the way Amazon handled the problem.

In 2009 - I bought my Watts 270156 12-GPM 1-Inch 110-Volt UV Disinfection System - and in less then a year the power adopter is already dead. Not only is it very hard to find a replacement power adopter online and they are very expensive - but also when you contact the manufacturer they take a few months to reply to you. Try getting a replacement adopter for this unit.. its probably easier to fly to China and buy it directly there. Never buy another WATTS!2017 Update after replacing 2 power adopters now again cheap substandard power adopter fails and again it is hard to find a replacement.Fyi you should consider this when purchasing this uv filter that you will most likely need to buy a new power adopter every 3 years for the rest of your life.

Having read other reviews I was a little anxious about it arriving all in one piece. It was just fine which was a pleasant surprise. The unit is easy to install and the instructions are clear. The only problem with it is that the UV light generates LOTS of heat. So, if you don't run water for several hours or overnight, the unit gets hot to the touch and the water that sits in it during the lull is also pretty close to hot when it gets to your faucet. I called the manufacturer and they recommend putting it on a timer so that it goes off overnight or while you are away. But a quick midnight trip to the bathroom then defeats the purpose of the unit. We found that putting a small fan hung from the ceiling blowing on it resolves the heating problem and ensures that the water continues to be purified. Good value for the money.

The first package arrived damaged and the crystal tube was broken. Unfortunately I had already shut off my water and re-plumbed everything for the UV system, before I discovered the broken crystal. Was able to exchange it quickly and the second one arrived undamaged.The packaging for this is poor. The metal tube that holds everything is heavy and it is shipped in the same box as the bulb and the crystal tube. The only padding on the bulb and the crystal tube is a foam sleeve. Nothing stops the metal tube from banging against these during shipping. There should be warning labels all over it and there isn't.When I tried to install the water system for the second time I knew this time to plumb in a shut off valve with a bypass so that I didn't have to shut off the water to the whole house in case it didn't work the second time or for future repairs or replacement. When I VERY gently put it all together all was well until I slid the bulb into place. The weight of the bulb cracked the crystal. The crystal is definitely the weakest part of this system. It is EXTREMELY thin and fragile. I don't think I would buy this product again, too delicate. The hassle of re-plumbing everything not once but twice and then to have the crystal break again is just not worth it to me. I did re-order another crystal, not much choice at this point. I read the other reviews about it being fragile and thought I would take my chances and really wish I hadn't.*Update: Third times the charm, finally got it installed and working. I do notice the improvement in taste in our water and feel confident our water is pure. But if I had to do it again I still would buy another kind.

We've been using this UV filter for 4 months now with no issues. It has been sterilizing our catchment water and providing clean water for the entire house. We try to make sure our system keeps the flow rate below about 10 GPM. We haven't tested our water in a lab, but numerous people have used our house water and there hasn't been any problems.It was easy to mount, plumb and put into service. I set it up with 2 union fittings so I can easily unclip it from the wall to change the UV bulb when it fails.

I bought two of these. One for each of my houses. A very good product and 40% the price of the local store. Easy to install and a must if you want to drink your catchment water. Catchment is the #1 way we get our water in east Hawaii and it can contain bacteria and things like Leptospirosis. Which will make you very sick. The UV light kills all these bacteria and more. And you should replace the bulb once a year.

This product sat around for a few months waiting to be installed, and once pressurized it began leaking immediately through the top. Being a licensed plumber I've installed this type of equipment before, so it isn't a matter of improper installation.This kind of thing happens when products are shipped, so I understand.The reason that I'm leaving this review is because I can no longer return this item due to time restrictions. Unless you install this item right away and know for sure that there aren't any issues, you won't be able to return it.I would appreciate the company allowing me to return this item for another. Customer service is appreciated.

Good quality, easy to install, work very good, no odor and kill all bacteria in the water!!! i install this with two watts WH-LD (one 50 micron and one 5 micron) the bacteria problems is solve!! thanks Watts!!! :) i recomend!!!

Excellent system, however if you live in Canada, be prepared to pay nearly half the price of this unit again if you break the sleeve...! :(

This system is awesome and super easy to install. Works beautifully on well water.

I can't believe I paid almost 500 bucks for something that arrived in a cardboard box that looked like someone dropped it out of a moving truck. It looked like Bagdad shipping dropped off.Also, getting 1" fittings to plum this was a bit of a pain. Had some at HD but was forced to go with 90 degree as was all that was available.Water has been consistently clean since install.Good product but for that kind of money, please take a tiny bit of pride in packaging it (though it wasn't actually damaged).The instructions were lame as well. Put some effort, i.e.; specs, troubleshooting etc. WATTS is terrible for this type of thing*UPDATE, two years later, its time for new bulb/quartz and guess what? Finding parts is like finding a virgin in Fort MacMurray. What a joke.
