Pump replacement
3 months ago
Exact replacement for a 12 year old pump. Very satisfied with Leslie service who did the installation. Very timely and well done work. Couldn't be happier.

Good Quiet Pump
2 years ago
Purchased this pump to replace old one that stopped working. I ordered it on a monday, it was delivered to my home on Thursday, very fast for free shipping! Easy to install, my neighbor did it for me. It pumped water through my system with no problems, including my rooftop solar panels. I wasn't sure if it would be that much quieter than my old pump, but it really is! I was able to speak in a normal tone to my neighbor while we were standing next to it, I use to have to shout above my old pump. .. more

13 years old, and started a leak today
3 years ago
In 13 years, the pump is 100% original. I just installed my third motor this morning, and now the pump is leaking. I may have cracked the seal plate. I am not sure if I should try to repair it, or is it time to buy a new one?

I'VE had this pump (1.5hp) for 13 years and no problems even though I've abused it, it ran
hot while I was at work because had air in return line and very little water getting to pump. When I removed lid it was steaming. I thought for sure it was a goner but let it cool down then primed it and its been running for a year since that time.
