My pump quit after 9 years of service. I did check out another pond supplies outlet in Hamilton, and they quoted me $300 dollars for a replacement pump. Problem with that is the new pump would be even more powerful than the one I have and I would have to deal with an overflow issue. The solution would of entailed more plumbing to regulate the flow.
Called Harpers, the same pump was $350, and they could not match the price of the other outlet, but, they offered a probable repair solution to my old one.
Took my pump down to their pond centre and Darcy went to work on my pump. She was amazing. She spent over 45 minutes with me and managed to match up my worn out and broken impeller with a new unit. She installed the new one and tested it right there.
Pump has been running issue free for a month now, and total cost was only 75 dollars. Now that was great customer service !
