Genuine Davey 57-SERVKIT-RN UV Service Kit – Lamp, Sleeve & Filters

Genuine Davey service kit for KUV57A and UV57 systems with prefiltration. Includes UV57LAMP, UV57SLEEVE, 2 O-rings, a 20-micron pleated filter, and a 1-micron polyspun filter, everything needed to service both the filtration and UV stages in one order.

What's Included

Compatible Systems

• Davey KUV57A
• Davey UV57 with prefiltration

Check your existing system model before ordering to confirm compatibility.

Filtration Sequence

20 micron poly pleated (20PP10) removes larger sediment and particles first. Water then passes through the 1-micron polyspun cartridge (1PS10) for finer filtration before reaching the UV chamber, where the UV57LAMP and UV57SLEEVE deliver treatment.

Handling the UV Lamp and Sleeve

Avoid touching the glass surface of the UV lamp with bare fingers, oils and contaminants left on the surface can affect performance. The UV sleeve is fragile and should be handled carefully during removal and installation. Make sure the supplied O-rings are correctly seated during reassembly to maintain a proper seal.

FAQs

Is this a genuine Davey product?
Yes, this is a genuine Davey 57-SERVKIT-RN service kit.

What systems does it suit?
Davey KUV57A and UV57 with prefiltration. Check your existing system model before ordering to confirm compatibility.

Is this just a replacement UV lamp?
No, it's a complete UV and filtration service kit. It includes the UV lamp, sleeve, O-rings, and both replacement prefilter cartridges.

What order do the filters go in?
20 micron poly pleated first, then 1 micron polyspun, then UV treatment. The first stage captures larger sediment before the second provides finer 1 micron filtration.

Why replace the filters at the same time as the UV components?
The filters prepare the water before it reaches the UV stage. Servicing both together, rather than replacing the lamp on its own, keeps the whole treatment sequence performing as intended.

How do I know if my system uses the UV57LAMP and UV57SLEEVE?
These parts are sized for the Davey UV57 chamber specifically. If your system is a UV24, UV80, UV151, or UV250, it uses a different lamp and sleeve, this kit won't fit. Check the model plate on your existing unit or your original purchase documentation before ordering.

Does this kit fit a UV24, UV80, UV151, or UV250 system?
No. This kit is specific to the KUV57A and UV57 with prefiltration. Each chamber size uses its own lamp and sleeve part numbers. Get in touch if you're unsure which kit matches your system.

Can I use only the filters or only the UV components from this kit?
Yes, there's no requirement to install everything at once. Some customers replace the UV lamp and sleeve on one visit and the filter cartridges separately if they're on a different replacement schedule. The kit is priced and packaged as a bundle for convenience when servicing both together.

Since the lamp, sleeve, and filters wear at different rates, how often should this full kit be replaced as a set?
UV lamp life is generally longer than filter cartridge life, so buying the full kit each time assumes you're replacing both together for convenience, not because they wear out on the same schedule. If your filters need changing more frequently than your lamp, ordering filter cartridges separately between full kit services may suit your maintenance routine better.

What tools are needed to complete a full service with this kit?
Beyond what's supplied in the kit, you'll typically need a filter housing spanner to remove the cartridge housings, and care when handling the lamp and sleeve rather than specialised tools. Isolating the water supply and power before starting is part of the standard procedure, not an optional step.
