Don't know whether the same service exists in USA, but here in UK the pump
mfrs will take back and repair (or sell you a refurbished) pump - costs
about 60% of new.

Just a thought ... Sincerely, Len.

Our pump went out after 7 years. Time to find a replacement. Our system
holds 3900 gal. The main pond 2900. The pump is submerged on the bottom
and pushes through a 1.5 inch line.

Recommendations? Operating cost and reliability are central in our
choice.
