The 5.7 had many problems for lots of people but mine has been working great for ten years. It is an absolutely stellar performer - very quiet and strong. It has no problems with surge and it runs very slow and smooth under low flow conditions.
I honestly don't know that I'd recommend it though based on all the failures. OTOH, Shure Flow was always good about replacing them for the folks that did have issues.
Mine was replaced by the factory 2 years ago with a -4048 (IIRC) and I hated it. It turned into a backup for the Flojet. I dont think they are servicing the 5.7's at all
