Urghhh....I turned on my 1500 gph waterfall pump and guess what...it has a mind of its own. It keeps starting and stopping and this is the one hooked to my uv filter so it's very important! Anyone have any suggestions on a reliable pump? I've not even had this one 1 year, it's a Beckett submerged, one of those that has no oil and is water cooled. I'm so upset. Any suggestions? I'm calling the company over the warranty but I don't want to encounter this problem again. Thanks in advance!
