Review: Perfecta para dosificación y tratamiento de agua.
Review: Super noisy yet tough little pump that can stand some fairly harsh conditions without a hiccup - This pump does the job 12 volt DC can take water High and it decent volume but I've had smaller that have pushed as much as it with a lot less noise. This units noise and vibration is it downfall. It is noisy, seriously. If you can get around that then you're all good as it has sturdy connections and a decent gauge of wires. Mine has been on nonstop for about a month and a half directly in the Sun pumping unfiltered Rainwater with fish waste without a hiccup. I'm not saying that it's, it's best use case, but is work for me in that application. So in summation: tough little unit stands up well in totally exposed elements and if you don't mind it's incredibly loud noise it's two thumbs up and four stars because of the noise
