Pentair PUV-8 8 GPM UV Whole House Water Treatment and Disinfection System New
I was impressed by FactoryPure's after-sale customer service, however they did did not make it clear on their website that they were selling factory stock, rather than inventory. As it turned out the Pentair was waiting for subsystem delivery from their supplier for the acid neutralizer, and it took over a month for delivery. The same item was in stock at Home Depot, but for over $100 more.
Would I order from FactoryPure again? Yes, but I'd check delivery first.
