Description
The VIQUA VH410-F20 is a whole house ultraviolet water treatment system with a built-in 20-inch, 5-micron sediment prefilter. Rated at 18 GPM at VIQUA's standard 30 mJ/cm² dose, it is sized for large homes with 4 to 7 bathrooms and light commercial use. It treats water at the point of entry, so every tap in the house is covered, and it adds no chemicals to your water.
UV treatment for well water and private supplies
UV-C light inactivates bacteria, viruses and cysts, including chlorine-resistant parasites such as Giardia and Cryptosporidium and bacteria such as E. coli. UV does not change the taste or odor of water and leaves no residual in your plumbing.
Sediment prefiltration that protects UV performance
Particles in water can shield microorganisms from UV light. The included VIQUA CMB-520-HF 5-micron cartridge removes dirt, rust and suspended particles before water reaches the 304 stainless steel UV chamber. For finer filtration, the CMB-120-HF 1-micron cartridge fits the same housing.
The VH410-F20 is a sediment-only model
The F20 uses a single sediment housing and does not include a carbon filter. If you also want carbon filtration for chlorine taste and odor, the VH410-F22 adds a second carbon housing.
Sizing the VH410-F20 for your home
VIQUA rates the VH410-F20 at 18 GPM at 30 mJ/cm² and 14 GPM at the higher 40 mJ/cm² dose. Size it by your peak water use, when several fixtures run at once, not by bathroom count alone.
Lamp life countdown and alarms
The controller counts down the days left on the lamp, from 365 to 0. When the lamp is due, it shows an A3 code and chirps as a reminder. If the lamp stops working, the display goes blank and an alarm sounds, so you know your water is not being treated.
Check your water quality first
For best results, VIQUA recommends iron below 0.3 ppm, manganese below 0.05 ppm, hardness below 7 gpg, turbidity below 1 NTU, tannins below 0.1 ppm and UV transmittance above 75%. If a water test shows higher levels, add pretreatment before the UV system.
Installation
Install indoors on the cold water line at the point of entry, before any branch lines. The system mounts on a steel wall bracket and has a 1" MNPT inlet and a 1" x 3/4" combo outlet. Leave room to pull out the lamp and change the cartridge. Plug the controller into a GFCI outlet. After installation, sanitize the plumbing as described in the owner's manual. The system runs on 100-240V, 50/60 Hz. To get an international plug (type F, G or I) at no charge, email customer support after you order.
Maintenance
Replace the S410RL-HO UV lamp every 12 months (9,000 hours). Replace the sediment cartridge every 6 months or sooner if water pressure drops. Clean the QSO-410 quartz sleeve at each lamp change and replace it every 2 years, or get both parts in the QL-410 lamp and sleeve kit.
Warranty
10 years on the UV chamber, 3 years on electrical and hardware components, and 1 year on lamps and sleeves. Made in Canada and/or the USA.

"ESP water products are easy to order from and supply good quality filters for our osmosis system. We plan on ordering more as we need them. Margaret / Gene G."
Excellent Recommendations
"ESP sales rep took the time to assist me in reviewing my family's needs, listening carefully to what I was trying to achieve. He then helped me walk through several options that ESP could provide and ultimately helped me choose and design the right system. I was impressed that the system design he recommended was actually much less expensive than what I had chosen on my own. Great sales staff, friendly and knowledgeable."

Q&A
Frequently Asked Questions
Q:
What flow rate is the VIQUA VH410-F20 designed for?
A:
The VH410-F20 is a point-of-entry system rated up to 18 gallons per minute at the published treatment dose, making it suitable for many larger homes and light-commercial applications. Select by peak simultaneous demand, not only household size.
Q:
What prefilter is included with the VH410-F20?
A:
It includes an integrated 20-inch, 5-micron sediment prefilter ahead of the UV chamber. This single-sump F20 model does not include the additional carbon stage found on two-sump F22 configurations.
Q:
What plumbing connections does the VH410-F20 use?
A:
The integrated assembly uses a 1-inch MNPT inlet and a combination outlet that accommodates the specified 1-inch or 3/4-inch connection. Confirm local fittings, bypass and service-clearance requirements before installation.
Q:
Which lamp and sleeve fit the VH410-F20?
A:
The replacement lamp is VIQUA S410RL-HO. Current VIQUA references list the QL-410 lamp-and-sleeve kit and the model-specific QSO-410 sleeve; verify the sleeve number for your system revision before ordering it alone.
Q:
How often are the lamp and sediment cartridge replaced?
A:
Replace the UV lamp after about 9,000 hours, normally every 12 months. Replace the sediment cartridge when pressure drop increases or at the interval required by source-water conditions; inspect the sleeve during annual service.
Q:
What incoming-water conditions help the UV system perform correctly?
A:
Water should be pretreated as needed for low turbidity and acceptable iron, manganese, hardness and UV transmittance. The included sediment filter helps with particles, but additional treatment may be required based on a water analysis.
