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

Easy to install, works great! Customer Service is excellent!

New ballast was much larger than the old one but was easy to install and works great. Very pleased with product.

So stupidly I bought a non genuine S36RL tube which as it ends up looking after the fact is not manufactured with the correct pinout. It instantly took out my 20 year old NLA 4 wire BA-ICE-1F ballast. So the replacement 3 wire BA-ICE-S (that probably would have run the generic tube) is $190. Or there is this intriguing guy. Got it, opened it, and it is awesome, a ballast in a little aluminum shell case, with a nice GROUNDED line cord unlike others and nice little headers for connections. Popped off the factory lamp wire that came with it, figured out the connections for the 4 wire VIQUA stepped end connector, cut the old cord off the dead VIQUA, and back together and running in less than 10 minutes. I did tin (solder) the ends of my wires but you probably could get by without doing so if you depressed the releases on insertion. Need a multimeter to pin out your tube, a #1 phillips, wire strippers, soldering iron if you want, and a tiny flat driver to depress the releases. You can actually buy the ballast that is internal to this case (without the case, cord, LED) and it COSTS MORE than this assembly. Will it last, who knows I will buy a spare and risk it. I can buy 5 of them for the price of the OEM.

ok

Does the same Job as much more expensive ones!!!

These ballasts fail constantly. I have replaced 3. very poor quality.

Works great. Changing bulb needs a lot of room so consider before Install. One bulb was broken out of the two they supplied

It seemed to work great, until it didn’t. Have had it under a year & just noticed that the bulb was blown; but it’s not just the bulb, it’s the ballast too. I can’t see any way to contact the seller’s customer support.

I added this to my water filters and passed the water test with flying colors.

Arrived quickly, well packaged and great product. I loved that I received a spare bulb and the assurance of full replacement warranty. I recommend this product

Failed the water test, installed this test cam back perfect! As soon as it was ordered seller sent an email with contact info to reach them if there are any issues stating they would replace any missing or damaged parts with 2 parts. No issues came up , easy to install, no leaks and works great would recommend buying from this seller!

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.
