We had a grundfos pump on the mainland for over 15 years. Ran like a champ and as far as I know it's still going strong. Personally I liked not having a pressure tank and that it ran off 110. Yes it will run any time a tap opens and as for noise it was in an insulated crawl space so it didn't bother us. Am looking at converting my current system here to a similar setup but far from the main house cuz of the noise. Our current flojet pump works well except for the light dimming startups. I hate the up and down pressure of pressure tanks and liked the constant set pressure of the grundfos. Imho. The only thing that concerns me is that oftentimes what works well one place doesn't necessarily do so in another. Hence reading these forums and listening still the best bet!
