Unfortunately this unit was far from the 'plug and play' I was hoping for - I can't quite match the advertised 300 Gpd which isn't exactly a system are malfunctioning (I have very hard well water). However, the support issue was easily resolved, they sent replacement diaphragms and a new flow restrictor (which helped). I've had this system for 2 years now, I only use it in the summer months to fill up my pool and fountain, but now the pump has just failed. I bought another one from Revain as I'm out of warranty. The electrical switch overheated but Nick was great and replaced it for free (although I was no longer under warranty). but the support (and Nick in particular) made it possible to do business with Ispring.
