Pump problem? Campump T4000 Torpedo
I'm not sure if I'm looking for advice or just to lament. For my new pond last year, I purchased a Calpump T4000 Torpedo pump for my pond from 123Ponds.com. The pump stopped working in November. I went through a painful replacement process with 123Ponds, of which I had to scrape off the UPC/SKU label from the pump, send it to them, and then they sent me a replacement pump and I sent mine back in. Of course, the manufacturer rejected my pump since it didn't have the UPC label on it, which 123Ponds apparently lost, and my card was charged for a new pump. (Still a little bitter about that. Lesson learned - send everything, including the label, with tracking.)
I received my "new" replacement pump in February and got the pond running again. Today, the pump stopped working again. Same symptoms as before, it stops working in, I find out it tripped a breaker, and it seems to be toast.
The pump is submerged, on a GFCI breaker (pond is about 2000 gallons). The timeframe seems to be consistent - this happened both times around 5-6 months after we started using it. Now, if I plug it in it starts up and immediately trips the breaker.
Any ideas? I have a call in to 123Pond to see what my options are, not that I'm at all confident in what they can help me with without charging me for another pump. Has anyone used this pump before? Had similar issues? Have recommendations on a better pump?
