We're off-grid, in a tiny space, and I've been faffing around with water filters for 3 years now and got to the point where I was entirely over it, and entirely over our Reverse Osmosis filter.
I hemmed and hawed for a few days before buying this filter because of the price compared to other UV filters we could use in our setup, but then I realised that because of how little water we take from it, and its flow switch, with a 10,000 hour bulb life, well, the UV LED was going to outlast either of us by actual hundreds of years at our current ~6L/day usage, pay for itself in my sanity immediately, and pay for itself financially in RO membranes (and 12V pumps that don't cark it prematurely from overuse) in just a few years. I ordered the filter over the weekend and it got to us today which means NZ Pump and Water Filters got it out first thing Monday (cheers for that!).
I've got no way of knowing if the UV-C is working, I assume that it is and I'm never going to test - we're on rainwater and filter heavily before it gets to the UV filter, it's probably always been fine, and probably always will be - even with the occasional birds and rodents and possums that find their way onto our roof to hang out and party overnight. I'm just pleased to have the peace of mind something like this offers - we will always have drinkable water (assuming effective pre-filtration prior to the UV-C) and it's nice to feel like I can take that for granted - and nice to do it without an RO.
Finally, just a note in the same vein as Paul the first reviewer. We're also 12V. It's not the first thing I've cut the wall wart off of and hardwired in directly. It is the first that cost ~$800, and the first to not work immediately when I wired it in. I about needed to change my pants. I don't know whether 12V is too low-voltage to do any damage if the polarity is reversed or if they included some specific reverse-polarity protection, but either way after I switched the wires around it's working now (thankfully!). So for future 12V would-be-hard-wire-ers-like-me-who-know-just-enough-to-get-themselves-in-trouble...the wire with dashes is the negative (new one on me). The safe thing to do, of course, would have been to plug in the newly liberated wall wart and test directly from the wall without putting the UV filter in any danger, but hindsight is 20/20.
Anywho - cheers NZ Pump and Water Filters for your super fast service and for being the distributor for this piece of kit that's going to outlast probably anyone who ever reads this review.
Thank-you. For making an easy to install and operate unit available.
Would be a good idea to have a couple more adapters in the kit as we struggled to get a 10 or 13mm pipe to connect to the pre filter.
Cutting the transformer off to connect to 12v battery (off grid system), via a fuse was a bit nerve racking, but has worked out.
Otherwise all went well.
Thanks for your feedback
We will check on the fittings to ensure this is easier in future
Enjoy this exciting new technology
