HQUA-OWS-12 120V 40W 3/4" MNPT Inlet/Outlet Whole House Ultraviolet Water Purifier Filter, + 1 Extra UV Bulb

Installing the device was kind of difficult, after the 3rd attemp and applying the lube they provide for the O ring it worked. I contact the seller because the tube was broken, they responded very fast and aent me a new one, thumbs up for that.

Well, this all started about 3 weeks ago when all of a sudden my wife started getting sick. And then she started to lose her balance. We were thinking that she had a inner ear infection. Well a few days later I went to get a drink from the sink and smelled mold. I'm like what the??? We have been at this property (well water) for over 5 years, and it's always been the very best water in the entire area (admitted by my neighbors). So when I realized we had mold in our well I was shocked. We had just replaced all the plumbing including the pressure switch and pressure tank. So everything was new. So I immediately got on Amazon and started looking for a UV sterilizer. There are a lot to choose from here and most are in the $250-$400 range. I was not ready to pay this much for a UV unit and found this one with no reviews. I was very leery and put it in my list and kept looking. But after almost 4 hours of looking and reading reviews I kept coming back to this one. I finally took the chance and ordered it.I am glad I took the chance. It took two days to get it (Thanks to Prime). I was pretty apprehensive about this, as I knew that there was going to be glass involved and was even more nervous when I opened the first box to find the second one from China. My heart sank and I really thought I had just got taken. But I steadied myself and opened the next box. And this is when every bad thought that ran through my head took a flying leap.I cannot begin to tell you how well this item was packaged. I really wish I had taken the time to take some pictures but since I did not I will describe it to you. Everything is wrapped and double wrapped in heavy duty air bags and bubble wrap. The main case of the light is polished Stainless Steel and is very large ( almost 3 feet). It comes with two bulbs and one quartz protection tube. All three were wrapped with bubble wrap and then inside was three hard cardboard tubes that were also bubble wrapped inside to protect the glass. This level of protection would pretty much save this box from most of the damage it could receive during shipping.The instructions are pretty easy to understand but you need to be extra careful when putting the two gaskets on each end of the quartz tube when inserting it in the main body. Don't let them roll and twist, make sure they are flat against the metal so as to get a good seal. At first I was worried about clearances as the quartz tube gets sealed in the unit on both ends with screw on caps, but it was for not. Everything went together perfectly. Once the quartz tube is sealed up there is a hole on one end that the UV bulb slides into. Then you just hook up the ballast wire connection and slide the cap over it. I used a black zip tie to help keep out the moisture.I then hooked it up to a 3 stage filter system and let it rip. We also sterilized our well with a gallon of bleach and we let the whole thing run for two days before hooking up the filter system. Then after the filter UV system was hooked up we ran it for another full 24 hours before drinking.It was worth every penny. It has been a week now and my wife is feeling much better and the water no longer smells like mold. In fact it has no taste at all. It's clean and great to drink. We even run our swamp cooler through the UV part just to keep the evaporated water from being able to expel anything.This is a high quality UV light Sterilizer and worth every penny I paid for it. Not all come with a extra bulb and none of them come at this price with a extra bulb. The ballast unit has two lights on it, one green and the other red. These indicate the condition of the ballast and the bulb. They both stay on when everything is working right. It's nice to see at a glance that the unit is working as it should. At night you can see the UV light glow through our water hose : )So buy with peace of mind. I did not get this item at any discount or for free. I purchased this with my own money and took a chance. Now you can buy without those issues and perhaps this seller can make a living selling a good quality product.

This is a great product. After reading the reviews we decided to purchased this UV and are very pleased. We noticed a difference in the water quality immediately. I wish we would have bought this earlier. Customer Service was very helpful when we needed it.

I had my UV water sterilizer in service for over a year and a half without any issues. I replaced the bulb after the first 12 months, but about 7 months later the fault alarm was sounding with the red error condition light showing. I contacted the manufacturer and they quickly diagnosed the problem as the bulb and sent me a replacement. I really felt like they were concerned and promptly got me going again.

Very quality. Compact and looks great. Easy to install and no leaks. Comes with extra bulb too

We installed a whole house filtration system in our house last year. We've followed all recommendations and had a professional recommend a UV light as part of the system because we are on a private well. The system has several filters and we added this bulb to take care of any bacteria. We just replaced the bulb and the tube for regular maintenance along with all the other filters that the system uses and had the water tested a few days afterward. IT FAILED!!! the total coliform bacteria!!! I struggled to find any contact information on the seller, eventually did and sent a note via email, they are in China.....to trouble shoot, but honestly, if the UV light doesn't take out total coliform (which all water systems check for routinely), it's not taking out others. We spent SO much on having this system installed. Please have your water source tested if using this.....it may be doing NOTHING!

The replacements arrived yesterday and the 1 we put in is operating just fine. Thank you for the excellent customer service.

Unit installation wasn’t too hard. I did use plumber’s tape as recommended and had no leaks.I did need a replacement quartz sleeve and customer service was great and shipped me two within a few days.
