Pentair UV problems

[wgregww]

What’s with all the bad reviews of the casings melting on the Pentair UV’s after a year? I’ve seen multiple reviews with the same issue, scared to buy one so looking at option no.2

I have had my Pentair since 2016... Zero problems. I run it 24/7.

Maybe it’s people running to slow of water flow.

Same here but since the 90’s and still working like a champ

I've run 18w, 25w and now 50w Pentairs over the years also always 24/7. Top notch no issues either. Opinions will vary all over on high end vs. budget friendly brands. Any brand can have a bad unit here or there and typically when that happens is when someone will leave a review. My personal opinion is the higher end units are worth it if you're looking for longevity. I've run cheaper quality UVs on freshwater tanks and ponds for water clarity purposes.

I don't see how this could be an issue unless the lack of flow somehow raised the temperature to the melting point of PVC which is laughable.

I agree :beaming-face-with-smiling-eyes::cool:

I'm one of those who has experienced this issue. More disappointing is the lack of empathy or accountability from the Pentair Customer Service department.
But there it was: my kids came to tell me that they smelt burning plastic. I found that the vertically mounted UV50S was emitting smoke from the top cap around the cord. Disassembly revealed that the ceramic four-pin adapter had melted and that the lamp, gaskets, and quartz sleeve were damaged.
I contacted Pentair to ask about this situation on such a high end UV. Instead of asking anything about age, condition, usage, or even serial number, I was simply directed to buy replacement parts from their website - which cost $400+ - or almost half the original purchase price. Ridiculous!
The unit was purchased in Nov of 2020, lasting just about 2 years (I didn't install it until the tank was cycled.) While I see many here saying they've had nothing but great luck with their Pentair, mine has been a horrible experience that I hope everyone who considers purchasing Pentair products understands.

I know this is a two year old post but this just happen to me recently. Any ideas on what the root cause is?
