Can I install this unit with PVC pipe?

Can I install this unit with PVC pipe?

Why does my water have an odor after installing this unit? Just installed yesterday.

Asked by: Larry
Hello Larry, Did you sanitize the plumbing lines before start up of the UV? Please find some suggestions for sanitizing your plumbing lines in units operator manual or go to for procedures to sanitize a well. Otherwise it could be sulfur. Just a low amount will be oxidized by the the UV light if. A quick test is to run water and turn the UV light off. If the smell goes away then you need to check for sulfur from the well. Thank you

WIll it work with higher grains than reccomended?

I have 550 ppm out of the well I DO NOT want a salt based softener. I plan on using a "Descaler" which technically does not soften the water can I still use this system?
Asked by: sqounk
Descaler equipment is designed to prevent mineral buildup on the inside of plumbing lines. They do not remove hardness but allow it to pass down stream . There would still be the potential for calcium build up on the quartz sleeve of the UV units. I would recommend that you inspect the Quartz sleeve for any build up after 30 days of use. The amount of build up will determine how often you have to clean the Quartz sleeve.

Why has the unit started leaking

The unit was installed by a professional plumber four months ago at the finishing of construction on a new home. Now it leaks about a half gallon a week. It leaks from the top of the unit where the cord goes in. The leak is not continuous and not associated with water softener needs or water needs.
Asked by: Kilomike
From what you are describing the leak could be caused by the O-ring on the quartz sleeve not making a tight seal against the end nut. You could release the water pressure and tighten the end nut down slightly by hand then turn your water back on slowly. If you have additional questions please call us at 800-788-4825.

Can this unit be mounted horizontally?

I have a need to mount this horizontally along the wall instead of vertically. Please advise. Thanks,
Asked by: realdeal
Hello realdeal, The unit can bemounted horizontally but is not recommended because of air bubbles. If you need further information here is the link to the manufacture site for the installation and the manual for operations. If you have questions about test result see the next link. Thank you for your inquiry. Charlotte

Rated 4 out of 5 by from Installation issues Warning I cannot report on the quality of the operation of this unit because I broke it while installing it and I am waiting for replacement parts. It did not break because the quality is inferior. I broke it because the installation instructions are very badly written. The installation instructions are not sequential. They are beyond confusing they are not accurate. They use three different terms for the "End Nut" in the "Installation of the Quartz Sleeve", The instructions should caution you to remove/separate the "End Nut" from the "Brass Shroud" before installation. I only discovered this AFTER I cracked the Quartz sleeve. The description of how to install the Rubber O ring makes no sense. It tells you to "install the O Ring down the top of the Nipple" and "Avoid riding the O ring on any threaded part of the Nipple" as if you are installing the O ring over the threads. This is incorrect and very misleading. You are not told the "End Nut" which is called the "Compression Nut" or "Gland Nut", depending on which part of the instruction you read, must be removed from the "Brass Shroud. Were I packaging this unit I would never ship it with the "End Nut" already Installed in the "Brass Shroud" because once it is installed it looks like it is one piece. As a consequence I tried to install the "End Nut", which is mistakenly called the "Compression Nut" in the instructions, while it was still inside the "Brass Shroud" this resulted in my twisting the "Brass Shroud" cutting the "Rubber Grommet" and slicing into the "Shrink Tubing" which exposed the wiring to the "UV Bulb". My suggestion Remove the End Nut from the Brass Shroud. Insert the Quartz Tube Into the Chamber per instructions Install the Rubber O Ring onto the glass Quartz Tube and move it down until it is SEATED onto the top of the NIPPLE. Install the End Nut over the Quartz Tube onto the nipple. Gently tighten the End Nut until the compression shoulder inside the End Nut contacts the O Ring. Use only finger tight pressure. The next step is to install the UV Bulb. Gently insert the bulb into the Quartz Sleeve. While holding the bulb connect the plug to the pins on the bulb. Refer to "Installation of Ultraviolet Lamps" Gently lower the bulb into the Quartz Sleeve and slide the Brass shroud onto the End Nut. without twisting. I strongly recommend the manufacturer rewrite the installation instructions. Hopefully this will help others who choose this product.

Rated 5 out of 5 by from Quick & easy to install I wasn't planning to add UV filtration to my house, just a house filter. I thought, "$500 is a good chunk of change, and we've got pretty good water around here." Heck, even the filter was almost a redundancy. The next day, the morning news said: " ______ County water advisory- boil water order in effect... E-coli... fecal coliform...etc..." I ordered my filter that day. No regrets. After all, how much fecal coliform bacteria do you really want in your drinking water? The unit installed in less that a half hour, as part of a whole-house filter installation project. Basic plumbing/soldering skills required, but if you have those and can follow basic directions, no problem. The blue light lets me know from across the room that my water is being sterilized. I haven't tested water samples, but UV is pretty foolproof. I sleep better knowing my family is drinking clean water.

Rated 1 out of 5 by from Horrible Instructions and Customer Service Robbie's review and comments are spot on and I highly suggest watching his video too before you try to install the device. I broke my quartz sleeve while trying to change the bulb after its first year. Called the company and ordered a new sleeve. They sent a bulb but not the sleeve. Long story short their customer service is horrible. Not really sure this a company I want to trust my water filtration needs to.

Rated 4 out of 5 by from Nice unit poor instructions Great unit. Constructed well. The installation instructions are poor at best. I am a great part change with instructions. This was a great part but lacked the reasonable instructions one needs to do the install. Mine came without a washer that was needed for the install. I called and after spending a lot of money on unit they charged me .85 cents for the missing washer and $5 for shipping. Wow they were helpful on that issue. Find the YouTube video it will really help to understand how the unit is put together and installation process. Make sure you have some plumber's grease to start the job.

Rated 4 out of 5 by from clean water A couple of months ago we noticed a smell in the water. It tested positive for coliform bacteria. Our water softener tells us how many gallons per minute we use so I cracked open all of the faucets, got the reading and ordered the sterilizer that we would be sure wouldn't be over powered by flow. Just had it tested again yesterday. Clean water. I'm very happy with the results. There are a couple cons though. When you mount the unit it needs to be done in a way that allows removal of the bulb. I mounted mine horizontally, which isn't the normal mounting position but allowed me a better use of space for bulb changes. The seal and cap around the wiring harness is questionable but after some Teflon and a little more tightening, be careful, you'll break the tube, everything is water tight.
