  • Simple, Inexpensive and Effective
Size: 3/4" MNPT
Replaced a much more complicated "top of the line" UV system that had expensive electronics that failed. This system is simple, little can go wrong, and works great. DIY install. Excellent product.

  • Easy install, great design
Size: 3/4" MNPT
Easy install. Used to replace 15 plus year old system. A little worried sediment might build up at the bottom. But we shall see given time. Mahalos

  • Well constructed-Very well packaged
Size: 3/4" MNPT
The system was complete. It was easy to install and it has been operating continuously for about a month. The only recommendation I would have is to make a note that if the system is installed with PEX piping, (as it is likely in many homes), that there should be a note/caution about getting some piping (I purchased some flexible metal pipes) to keep the PEX away from the detrimental effects of exposure to UV rays. ... show more

  • The instructions recommend 5-6" of metal pipe coming out of the unit!
Size: 3/4" MNPT
First off, the unit works great. Had the water tested before and after, and the bacteria is gone. I have two issues with the unit. First, the in and out ports are not labeled. Are they reversible? I don't know. The instructions don't make it any clearer. One pictures shows the inlet nearest to the UV tube, the other shows it on the one further away. I resorted to looking at all the pictures here to figure it out. Which brings me to the second issue. Looking at all these pictures, most people are plumbing it directly with PEX, which was my plan. However in scouring the instructions to figure out the issue above, I found a note that the UV unit must be installed with 5" of metal pipe at the inlet and outlet, to prevent overheating and degrading the PEX, releasing chemicals into the water. I had to run out and get fittings and pipe in order to do that, and it really changed the whole layout, needing 10 extra inches of space. Both of these issues could be more clear in the instructions, and also in the product description. Clearly a lot of people are either missing the proper way to install it, or just don't care. ... show more

  • Great Customer Service
Size: 3/4" MNPT
It has been working non stop for couple of years. The uv bulb died, so the ballast stopped working. Seller helped me, very responsive. Thank you.

  • Works! Now a year later, time for yearly maintenance...with two howto hints
Size: 3/4" MNPT
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! ... show more

  • Fair product but the lights powersupply died within 3 months.
Size: 3/4" MNPT
I may have gotten a bad one but within 3 months my powersupply died which makes the extra tube and bulb kind of worthless..

  • Filter for ice bath
I use this UV filter for my ice bath, opting for it instead of an ozone system, and it performs exceptionally well. The setup was straightforward and hassle-free. The filter ensures the water remains crystal clear, which is crucial for maintaining a clean and hygienic ice bath environment. With a 1200 GPH pump running for 4 hours a day, the UV filter effectively keeps the water pristine and free from contaminants. Highly recommend this UV filter for anyone looking to maintain their ice bath with ease and efficiency! ... show more
