Hello fellow reefers. I just want to share an experience with you in hopes that it may save someone from the experience I have going on. I purchased a Reeflo hammerhead hybrid in Sept of this year. It has developed a noise that customer service at reeflo suspect is a bearing failing. Since the Reeflo website states the pump has a 3 year warranty I figure I'm covered. Well it turns out that the pump I bought at full retail price was old stock and has no warranty. Reeflo states the warranty begins on the date of manufacture and not the date of retail purchase. They state the retailer should not have sold me the pump. The CS rep at Reeflo states they make that clear to retailers which may or may not be passed on to the end user. Happy reefing and check the date of manufacture before dumping $450 on a pump with no warranty. It sucks because they make awesome pumps but with no warranty I now have an awesome paperweight.
