On a small-flow unit like this, even light scaling or scratching on the quartz can meaningfully cut UV transmittance relative to the water volume being treated, so disinfection can fall below a safe level while the lamp still lights normally.\u003c\/p\u003e\n\u003cp\u003eWrekinWater lists this as a compatible sleeve specifically for the SUV-S-4-1\/4, rated to the same 3.8 LPM flow as the original, drawing on 15 years of supplying UV consumables.
