WSP Conversion Kit, UV

Water Softener Plus offers a conversion kit designed to upgrade or repair your existing “d seri” UV water disinfection system. Instead of replacing the entire unit, this kit lets you restore stable UV lamp operation and keep your water treatment running smoothly without starting over.

The frustration of UV system failure without replacement

You’ve built your water treatment setup around a UV system to inactivate bacteria, viruses, and cysts — but now the power supply or control head is failing. The result may be water that’s no longer properly disinfected, with none of the safety measures you counted on. Buying a whole new unit often means a big expense and reinstalling everything from scratch. You’ve likely tried patching issues or settling for inconsistent operation, but the problem persists and the system can’t reliably protect your home’s water supply.

How the control head keeps your UV lamp working right

The heart of this conversion kit is the control head, which regulates the electrical current powering your UV lamps. Without stable electricity, the lamps flicker or dim, reducing their ability to inactivate harmful microorganisms in your water. This control head includes protective circuitry against electrical surges to prevent damage and interruptions. When installed, it restores steady operation to your UV lamps, allowing your system to consistently disinfect your water as intended.

The media you won’t see but rely on

Inside your existing UV system’s tank, the UV lamps shine through water to disrupt the DNA of bacteria, viruses, and cysts, making them inactive. This conversion kit fits tanks designed for the “d seri” UV systems, ensuring compatibility and proper fit. It does not replace the lamps themselves but restores the power supply and control needed for them to function effectively.

Tank and capacity matched to your home’s needs

This kit is intended exclusively for residential use within the scope of “d seri” UV water disinfection units. It maintains the original tank’s capacity and flow design, so you can expect it to continue handling your household water volume as before. It’s a focused solution for extending the life and performance of your existing system rather than increasing capacity.

Ideal for homeowners maintaining their current UV system

This conversion kit suits homeowners who want to keep their current UV water treatment but need to replace a failing control head or power supply. It is not for those looking to upgrade to a larger system or different technology. If your UV system is of another brand or model series, this kit will not fit, and you should seek a replacement or different conversion options.

What you get and what to expect next

Ordering the WSP Conversion Kit, UV means you receive the control head unit designed for “d seri” UV systems, shipped free anywhere in the U.S. No bypass valve or extra installation hardware is included, so your plumber will install the conversion in place of the existing control head. Once installed, your UV disinfection system should regain stable operation, extending its usefulness without a full replacement.

Who this size is right for

In terms of sizing, this is a residential system, sized to the flow the house draws.

There is no published capacity figure for this item, so we size it from your water rather than from a table. Send your peak flow rate and a water test and we will confirm what you need - it costs nothing and it avoids buying twice.
