HQUA-TWS-12 Ultraviolet Water Purifier Filter for Whole House Water Purification,12GPM 120V, 1 Extra UV Lamp + 1 Extra Quartz Sleeve

Easy to install with basic plumbing materials. Seems to work as my water tested negative for bacteria post installation. Seems cheap to run. Be careful installing the light / sleeve, very easy to break.

Great product! Easy install. I used a pre-filter before the carbon tank and a post filter after the conditioner tank to ensure no particles get into the UV light. Love the holes in the bottom cap that shows the light is actually on. Doesn’t come with any reducers as I use 3/4” hoses and the housing is 1”. Ensure you have rubber washers inside the reducer to avoid leaking as I originally had a slow drip with the pvc version I made from the home store before I went online and ordered better ones. Lastly, no adverse impact to water pressure, in-fact I removed an older water softener before installing this new system and my water pressure increased significantly.

This was installed at the end of a water filtration system. Fantastic results. Easy installation. Forget the cheap tape nobody can figure out and just use pipe dope. Rectorseal #5 and youll never get a leak. Comes with a spare bulb and spare glass tube. Great deal.

Yearly maintenance consists of changing the UV tube and cleaning the quartz tube. Remove the old UV tube and put aside. Next, following the instructions, shut off the water to the unit, drain that loop and remove the gasketing rings on each end. Remember that gloves must be worn when handling quartz glass as hand oil will eat at them. Remove the tube and clean it, as per the instructions. I have clean softened water so the outside of the tube was fine. What the instructions don't cover is that the UV bulb heat causes outgassing of the plastic guard on the tube...which puts a film on the INSIDE of the tube (like the film on the inside of your car windshield). How to clean it, the instructions don't say. HINT #1: Get a 24" claw mechanic's pickup tool like this: www.amazon.com/ALINNA-Flexible-Grabber-Bendable-Reaching/dp/B098F3VWDV/ and a piece of paper towel. Gather a dry piece of the towel up in a LOOSE wad with the pickup tool and gentle feed it down the quartz tube, turning it gentle to wipe the inside of the tube. Gently pull it out. Now reassemble the tube in the filter house and reseal it with the o-rings and collars. Put on the gloves if you haven't and feed the new tube in. Now HINT #2: You have to unplug the ballast and replug it after connecting the UV tube to the ballast 4 conductor connector. If you never unplug the ballast before connecting the new lamp, it won't come on. Hope this helps. My original review, a year ago...this still holds.=================================== I've been a professional mechanical contractor. The gear was was well made and straightforward to install. The one item damaged in shipment was replaced cheerfully and immediately; they even gave me two in place of the one busted one. That's service and customer attention!

Bad news, the ballast died, company assisted with troubleshooting. Confirmed dead in less than a year, so under warrantee. Company shipped a new one in 2 days! Great company, standing by their product.

The HQUA whole house UV water filter was easy to install and eliminated any question of microbial contamination for my well water. Although the packaging was very solid, I did need to request customer support for damage that appeared to have been caused in transit. With a single email, the damaged items were immediately dispatched and were in my hands within a matter of days. I would definitely recommend HQUA for their quality product and outstanding customer service.

This UV system worked to kill the coliform in our well water. It was quite the process to install it, but worth the trouble. First, we tried bleach/chlorine treatment that did not work. Bleach treatment took an entire day and it was a strain on our pump and septic system. The UV system was much more effective.

I bought the HQUA-TWS-12 because of its space saving ability with both the input and output lines on the same end of the unit. I still had to work a bit on plumbing to get it all to fit how and where i wanted to with a minimal footprint. I did not add the sampling valves as the manufacturer recommended because I have one right at the pressure tank, and many faucets around the house anyways. I can sufficiently test if there is bacteria in my incoming supply as well as if it is in my pipes. Plumbing and soldering the unit in took several hours, but the unit feels solid. I had zero issues with leaking after following the assembly instructions. All gaskets were provided. I have a thermostat control to prevent water heating during periods of no water usage (overnight and when no-one is home). The unit will heat the water in the UV sanitizer to 80 and turn off the bulb. Once the inrush of cold water cools the unit down to 70 it will turn back on. With this setting it does not take long at all to turn the bulb back on so no loss of UV exposure to any amount of water. I did have an issue where the ballast was not working properly. I emailed the seller and they promptly replied and within three days I had two new ballasts AND two new bulbs. Great response time and customer service there, thanks James. My only major gripe is that the ballast is not safety certified for North America UL, CSA, or ETL (US/CAN). Being in the certification world myself, I understand the importance of this certification. That said, the ballast construction seems solid although there is no way to tell without performing the tests to the applicable standard. (UL 935)
