Frequently Asked Questions

Q: What types of pathogens does the UViaLite System neutralize?

A: Surface and airborne bacteria, viruses, mold and odorous gases such as hydrogen sulfide.

Q: Does the UViaLite System harm the “good” bacteria in wastewater?

A: No – the ActivatedOxygen (O3) doesn’t penetrate the surface of the wastewater.

Q: Aren’t chemicals necessary to break down waste solids in blackwater tanks?

A: Most veteran RV’ers have discovered that flushing with plenty of water is just as effective as the use of chemical additives. In fact, enzyme based chemicals take 5-7 days to begin to work while the average RV’er dumps their blackwater tank every 3-4 days.

Formaldehyde based chemicals, while effective, are highly toxic, require special handling and storage measures and can be harmful to the environment.



Q: If a sink’s air admittance valve is stuck open or a shower’s water trap seal is depleted will ozone enter the living space of the motorhome?

A: No. That’s because the UViaLite System produces a negative pressure situation (suction) in the waste holding tank due to the thermal updraft at the rooftop vent pipe. The ozone will continue to flow up and out the rooftop vent pipe because it holds a larger volume of warm air than the drain lines in the sink or shower.

Q: What happens if the UV lamp fails while on the road or at the campground?

A: During the day the thermal updraft at the rooftop vent pipe will continue to exhaust odors to the atmosphere. At night when the thermal updraft isn’t as pronounced, odors might enter the restroom when the toilet is flushed.

Q: If the rooftop vent pipe becomes clogged will ozone flow out of the UViaLite housing in reverse?

A: If a waste holding tank is accidentally overfilled the rooftop vent pipe will become clogged shutting down the thermal updraft that entrains air into the UViaLite housing. Without this entrained air, the UViaLite System won’t be able to produce activated oxygen. When the waste holding tank is drained and the vent pipe is unclogged the UViaLite System will proceed to operate normally.



Q: Can chemical additives be used in conjunction with the UViaLite System?

A: Yes, but the perfume scent found in most chemical additives will be neutralized by the activated oxygen.

Q: How often does the UV lamp need to be replaced?

A: For optimal performance, we recommend annual bulb replacement. 

Q: Is the UViaLite System safe?

A:The UViaLite System was engineered to ensure that ozone flows from the UViaLite housing, through the waste holding tank and out the rooftop vent pipe. Odor and germ free air containing safe, trace levels of ozone may enter the bathroom for 3-5 seconds when the toilet is flushed with the exhaust fan on.



Q: If a waste holding tank is accidentally overfilled can wastewater enter the UViaLite housing?

A: The tubing that connects the UViaLite housing to the waste holding tanks extends well above the respective flood line of each tank. This ensures that wastewater will never back up into the UViaLite housing.

Q: Is activated oxygen (O3) harmful to the environment?

A: No – Activated Oxygen (O3) is as natural as sunshine and will convert back to diatomic oxygen (O2) in less than an hour. The UViaLite System’s natural oxidation process doesn’t add or take away anything from the environment.
