@@water_estoreI think their asking to see before/after results of treated water that would show scientifically that the bacteria is really being killed.
I read somewhere it takes 10 seconds to kill virus within 6 inches radius. If it only take millisecond for water to travel thru the tube with uvc light bulb in it, there is not enough time to destroy the virus. There need to be some buffering mechanism to slow down the water traveling along the long UV-C light bulb. The buffer may be a coiled glass tube winded along the light bulb. The thinner the tube, the slower the water travel. Anyway, it is an engineering problem may, or may not have solved by this product. I feel that I need proof that this UV-C filter is really reducing the counts of germs/viruses.
Hi Edmond when installed correctly and sized for the flow rate of your pump they work every time. We have sold thousands of these systems, there are well over a million in use today all over the world. We have customers with bacteria in their water, they purchase and install a UV system and the bacteria is gone. They are guaranteed to work.
@@water_estore Gary, they're asking for proof. The only thing you literally said was, "They are guaranteed to work" isn't proof. You did say you do free water samples right? Well, maybe you should do some free water samples of before installation and after installation. Gary, if you could please provide water sample proofs of water test samples of before UV installation and proof of water test samples of after the UV device has been installed, that would be great.
@@GumShoes21 Here is the proof guys...I had bacteria + Ecoli in my water based on lab test of water sample...I installed a UV light, took a new sample to the lab and guess what...no bacteria.

You have to take numerous factors into consideration, including: light's wavelength and strength, water condition, system configuration, light's efficiency decreases with bulb's age, etc. Some oversimplified examples: • A 25W bulb will sterilize faster than a 5W bulb. • Water with 350ppm contaminates will require significantly more sterilization time/power than water with 50ppm contaminates. • A brand new bulb sterilizes somewhat better than a 3 month old bulb, and significantly better than a 1 year old bulb. (Different types of bulbs have different expected lifespans. Their efficiency can vastly vary from beginning to end. It's usually recommended to replace a bulb every so often, regardless if it still lights up or not -meaning you don't always wait for it to burn out before replacing it.) * Many UVC sellers claim their bulbs have higher wattage than they actually do. They do this because they know people will pay more if they think they're getting a better product.
I have a handheld tv lamp that came with a uv die kit for finding leaks in cars ponds and other places it’s a strong one it came with the yellow eye glasses to protect the eyes .
i think depends on how you drink your water.. if you use hot and cold dispensers like me then you need uv disinfection in the tank/bottle you keep your water.. because after a day or 2 bacteria grows back in there.. at the minimum you just get gas in your stomach or worst hospitalized..
At the one minute 9 second mark it tells you as the water flows past the light it kills the bacteria. It varies depending on the flow rate of your system but just a few seconds.
Quick question for you. The viqua vh200 f10 uv with built in water filter seems to have the inlet and Outlet reversed am I correct on that? I thought the inlet was always on the bottom?
If the water flows1 gallon per minute I doubt that small one will keep the water in a whole minute to clean it of bacteria. That looks like it might hold a pint of water if there wasn't a tube running through the middle for the UV light.
It doesn’t need to hold 1 gallon of water. It will kill bacteria as the water passes through as long as the flow is what the system is rated for in gallons per minute
I just purchased and installed your V-200 UV light. I have it installed horizontally. The installation instructions dictate the outlet needs to be on top to purge any air from the system. I did all this but I realized the inlet is on the side where the light plugs in and can be removed. In the instructions it has the inlet on the other end. I assume this should not matter as there are no valves I can see inside the system. Am I correct with this installation? Thank you!
It does not matter a great deal when installed horizontally but typically the end where the lamp plugs in goes up in a vertical installation and that would be the output. You will be fine.
Great question. Because if the volume of water is greater than the system can handle it won’t give enough exposure for it to kill the bacteria. That is why they are rated based on flow rate.
Great question! When you install a UV system it will kill the bacteria as water flows through it. It will not kill bacteria in the water downstream of the UV. That water will reinfect the treated water so you need to chemically disinfect the whole house after installation.
I wanted to get a price , after I clicked on the web sight there was no price, so I clicked to exit. The time I waisted I can't get back. No price when I click, no purchase, no problem.
10,000 gallons per day is 7 gallons per minute but I doubt the water flows continuosly at the same rate. This one will handle up to 16 gpm waterestore.com/products/uv-dynamics-16-gpm-minirack-mr485-tp2-220
I have a question 🙋♀️ okay my husband and I are buying a house. The house has a well and a holding tank. When the water was tested it came back too high for chloroform and it was decided the homeowner would have a UV light installed. I’m still a little unsure how this works as far as the decontamination. If the water in the well and the holding tank are both still contaminated and say I turn a faucet on in the house, then contaminated water passes through the UV light chamber into my cup and is no longer contaminated that fast? And should we go ahead and chlorinate the well just for overall safer water? Please help!
Hi .. is it advised to keep uv light always on in my RO system ? It’s connected to direct AC input through choke. So it’s always on inspite of water is running through the pipes. Pls help
I'm going to install a UV light but not sure where it goes in the system. Should it be the last thing before the tap? So, water line in, Particle Filter, Softener, Charcoal Filter, UV light, Tap, is this correct? Thanks

"How Long Does it Take . . .". I actually had to skip through so much of this sales pitch to find NOTHING stating how much time it takes. I can fully understand why you would want to show what you have to offer those that need ways to filter their water.

As the water passes through the UV it kills the bacteria on it's way through, depends on the size of the UV. If you have an 8 gallon per minute UV and you pass through 8 gallons of water it will take one minute.
When they do water tests they only test for one or two bacterias. So who knows how many varieties are actually in water. Also does the system use mercury that dissipates somehow? If so, please explain where it dissipates to? Thanks
Municipalities typically test for ecoli and Choliform bacteria, which can lead to sickness and death. What other kinds of bacteria are you concerned about? No, UV systems use Ultraviolet light to kill the bacteria. There is mercury in the UV lamp but it never gets into the water.
Gary the Water Guy I just know there are many types of bacteria, some beneficial to our bodies and some not. There are more than two kinds. How does mercury help process if it doesn’t touch water? Why is it used with ultra violet?

A lot of people Google this question and many of them end up on that exact website, because they're the only people who can give a definitive answer since they're referring to one specific item under one specific set of circumstances. However, people are using that answer as if it's a general rule for UV lights, which couldn't be further from the truth. As you shared in your example, the answer to the question "How long does it take for UV light to kill bacteria and viruses?" greatly varies. That's why there's no standard answer to that question. If you're using a professional high grade medical disinfection system, it will be far more powerful than a handheld LED UVC wand. UVC wands can be effective, but they require a longer exposure time in very close proximity and can only do a very small space at a time. Also, they don't usually KILL the bacteria/viruses, but they damage their DNA so they cannot reproduce. UVC handheld wands, UVC water filtration systems, UVC fishtank kits and UVC hospital setups are all very different situations. There's no standard answer.
