Little Giant 3E-34N 115-Volt, 1/15 HP, 670 GPH Dual Purpose In-Line or Small Submersible, Oil-Filled Pump, 10-Ft. Cord, Blue, 503603

It is all aluminum construction (like the 12 year old one it replaced) just the screen is plastic. They haven’t overly cheapened it like so many other things have been.

Replaced 5 yr old failed pump. Same specs - works fine. Have used same pumps for 45 years - they last longer if I take them for the winter

Not a reliable product. This is the second one I’ve gone thru in less than 2 years. Poor quality. Avoid this product

I bought this pump to descale a tankless water heater, it run's around 625 GPH give or take 25-50 GPH depending on the height from the pump to the service valve's. I use a white distilled vinegar at 5% acidity it's not as strong as commercial descalers, and won't harm the copper heat exchange or the pump. You can place the pump in a 5gal. bucket hook up some hose and let it run for 45mins. without damaging the pump. The second way is to connect two hose's to the pump and service valve's for a close cycle. I'll find my money's worth of usages for this pump. I would recommend the Little Giant to home owners.

My wife and I own a salon and needed to replace a pump in one of our pedicure chairs. This is actually the second chair I have replaced one of their pumps. It was a direct fit and I did not need any additional parts to complete the repair. This pump is pretty heavy so shipping cost from other sites come into play. The pumps are good quality. Be careful you do not get air lock and keep the pump running because it will get very hot and can ruin the pump. They do get hot enough in those instances where you shouldnt try to touch.

These pumps are very unreliable. I've probably replaced 10 of these over the past 30 years since my backyard water feature (pond and waterfall) was first built. So they typically last 3 years. The newest one lasted 9 months. Has to be hard-wired in a potentially damp environment, so the warranty is voided as soon as I cut the cord. Without an extremely expensive rebuild to alter the plumbing, I'm stuck having to use LG pumps. I was seeing a light oil sheen on the surface of the water, so I suspect the shaft from the oil-filled motor was leaking, causing the motor wiring to short out. Of course, there's no way to prove (or disprove) this. When I buy yet another pump, I will cobble up an unattractive trip hazard and plug it into an outlet that I think is less than 10 feet away, so at least the warranty will remain valid.

25 years ago I bought this same pump to use in my hobby greenhouse. It finally stopped working. I hope it works as well as the first one.

They work well, but in Arizona only expect about 1 year of use before it will overheat and die. That said, still the best out there considering.
