Review: Great USA made pump! - A masterpiece! Made in America with great quality like all things here once were. 15' excellent quality power cord. The prime hole is recessed funnel like to make priming a pleasure. Great quality on/off switch, wonderful users manual, strainer included, light enough to move easily by both my wife and I. Solid cast Aluminum body, not hideous plastic. It pumped like a little fiend removing water from a flooded crawl space. Worked to empty our large aquarium in minutes rather that the old siphon procedure we previously used. We will be using it for occasional short duration flood irrigation of our yard from a nearby canal to augment our lawn sprinkler system in very hot spells. Remember this is a transfer pump not a continuous heavy duty pump. Suction worked well with an Apache 3/4" x 25' Rubber Heavy Duty Water/Garden Hose, Apache # 98108802, it did not collapse from suction. Also upgraded strainer to a 1" foot valve Parts20 TC2503LF which we used with a brass 1" pipe thread by male garden hose adapter found on ebay. For draining the aquarium we used a Graco 243082 or 243-082 Inlet suction strainer (with adapters from hardware store) the fine mesh kept aquarium gravel from being suctioned although we were careful to avoid sucking sand when possible. In short this a excellent product that works great, one of those purchases you will feel good about.
Review: Nice Pump - Works Great! - I bought this pump to empty water heaters we are replacing in a high rise condo. It takes less than 5 minutes to empty a 50 gallon heater. We now use it on virtually every heater we replace - drained an 80 gallon boiler last week in way less than 10 minutes! Need to watch the end of the hose - strong output, and it jumps around if there are calcium chunks in the water (we now put the drain hose past the trap in the toilet and monitor it - live and learn!) Nice quality, heavy duty aluminum body is light weight and compact and the long cord is really handy.

### ⭐⭐⭐⭐ A nice little pump
*by P***R on July 30, 2013*

Bought this because I'm a plumber and was replacing someone's water heater. Liberty makes good pumps. It has a nice long electrical cord. It comes with all the adapters for the hoses you need. It has an accessible plug that allows you to easily prime the pump. It's small and compact and drained a 40 gallon water heater in short time. I haven't had it for very long and have only used it once so I can't comment on it's long term durability.
