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

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.

I seldom post ratings unless I am exceptionally impressed with a product. This item was easy to install, is obviously quality built and works perfectly for our well water. The most impressive part, and what inspired me to write this review, was the exceptional customer service. When I first installed the unit, the ballast light came on briefly, then went out. I installed the replacement bulb that came with it, and it works fine. I sent an email to the company with the order info, and the next day received a response that they had already shipped a replacement scheduled to arrive the following day. After having so many issues with unanswered customer service requests, these guys were a breath of fresh air.

This UV filter helped clear up the bacteria problem in our well water. Water tested before the UV filter positive for bacteria after the filter no bacteria.

Installation was easy, used flexible stainless steel lines for inlet and outlet connections. Make sure to plug uv light into the 4 prong connection head before attaching to unit and securing with the detent clip followed by plugging into outlet power. Also make sure to use the sleeve/bulb side of the unit as the outlet side, otherwise there is a drop in water pressure. Overall a well built uv light, you will need basic plumbing skills and common sense, the provided instructions suck.

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!

Excellent design. Large capacity reactor chamber compared to competing brands. Comes with spare quartz tubes and UV tubes. Easy to install. Great customer support. Can't ask for more. Price was very reasonable too.

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.

Extremely pleased with the whole set up from HQUA. The whole house filtration system they offer changed my well water drastically. Very affordable as well. 10/10 would recommend. Easy install.
