Review: Good quality. - Work as it should. No leaks. Well made. Easy installation. No bacteria in the water.
Review: Works! Now a year later, time for yearly maintenance...with two howto hints - 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.desertcart.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!

### ⭐⭐⭐⭐⭐ Peace of Mind!
*by E***D on March 28, 2026*

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.
