Let’s talk about the sacrificial victims in your system. The UV lamp is the martyr. It hates being turned on and off constantly—that shortens its life to a mere 6,000 hours. Hint: leave it on for long stretches. Then there’s the flow sensor, a tiny plastic propellor that clogs with barnacle larvae. Clean it with a toothbrush or it’ll lie to you about water flow. Cost? About $80. Annoyance? Priceless.
The biggest surprise? The intake screen. It’s the first thing seawater hits. Over a year, it collects enough organic slime to feed a small village. If you don’t backwash it weekly, the pump works harder, overheats, and dies at year two. A pump replacement runs $500 to $2,000. A five-minute backwash routine? Free. You do the math, Captain Procrastination.

The Final Verdict: 10 Years Is the Sweet Spot
Most manufacturers say a seawater disinfection system will deliver 8 to 12 years of peak performance if you’re not a monster. After that, the coatings wear thin, the seals crack, and the electronics start acting senile. But here’s the humorous truth: a human can live to 80 with bad habits. A desalination system? It’s more like a professional athlete—it needs a coach.
Your coach is maintenance. Spend 15 minutes a month cleaning sensors, checking lamp output, and flushing the system with fresh water. Do that, and your system might just outlive your marriage. (Sorry, honey, but the UV lamp is more reliable.)
