Just bought this to build my own water filtration and purification system. There were a lot to choose from but glad I bought this one! Couple notes below.

1. The product seems very well built. Everything was tight fitting and easy to install! I used a 3/4 FNPT sharkbite connection to connect with PEX pipe.

2. I was worried about possible loss of water flow or pressure since there are higher flowing UV lights. However, after installing this, and other equipment, my pressure is actually about 5 PSI higher post filtration system!

3. They seem to really care about their customers. This product came with extra O rings, an extra hanger for the wall and an extra UV light. Not often you get more than you need! And they have a guarantee that theyll replace anything broken or missing with two items! Packaging was also impressive and very secure. Not your typical styrofoam padding, it was customer made cushions for everything to slide into.

Very satisfied with this purchase, packaging was insane I'm sure you could throw the box off a truck and nothing would break. Couple of comments to ensure your install is a success from the start: Install the supplied silicone O-ring onto the quartz "test tube" that separates the water from the UV light and cover the outside portion of the O-ring with a pipe dope, such as Great White (outside portion being the side of the o-ring that faces the end cap), you can pick that up at the big-box store or on google. Make sure to put the pipe dope on the outside of the O-ring so that it does not enter the tube and contact the clean water. Also always use Teflon tape and pipe dope on the threaded portion, applying each to the male ends of the threads only. In my case, I used Mega tape and Great White pipe joint compound. Do yourself a favor and install everything and let water run through it for at least 1 day to ensure no leaks, then you can install the UV bulb, just in case there is a leak, you do not ruin the UV bulb. My total install dropped by water pressure by 8 pounds, not sure if that is the result of this UV setup of the 1 micron sediment filter, but regardless to have clean water is worth it.

My wife found this first and told me about it. Did I research and read a lot of reviews? Yes! We got a positive coliform result back from a water sample I submitted to the lab. I already had a filter and an electric device in the hot water heater to replace the anode rod. It had been working ok and eliminated a lot of the sulfur smell. All other tests came back ok. So, I bought this system and installed it. I also installed an extra filter into the system. There's nothing difficult about doing this. Just measure where you want to install it, plan it out, go to your local hardware store and get what you need. I waited a few days then took another sample for the lab and everything came back with glowing results! No coliform and no e-coli. The UV light is zapping everything plus the smell is negligible.

I used this UV light in my water purification system with the iSpring WGB21B 2-Stage Whole House Water Filtration System w/ 4.5"X10" Sediment and Carbon Block Filters and the iSpring WSP-50 - Reusable Spin Down Sediment Water Filter - 50 Micron, 20 GPM, 1" MNPT + 3/4" FNPT. The water in my house has never been clearer and it no longer stinks. For the connections I used push connect couplings and valves by Procuru, Sharkbite, and Libra Supply.

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 google 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.
