The pump was excellent from start but I had trouble with attachments. Two were missing though I only notified vendors of one. The vendors were very helpful when contacted and sent me the missing part. I couldn't fit the 3 fountain nozzles and I didn't have the cap to shut off one exit hence the adjustable valve was forced into pond every time the pump was switched on. I decided to order another complete set of attachments which arrived today and bingo, everything is working perfectly. I would have given 5 stars if I hadn't had the above problems which were obviously not the vendors fault.
