Mellif Cordless Transfer Pump Compatible with Makita 18V Battery (Tool Only), Portable Self-priming, Electric Utility Water Pump for Garden, Hot Tub, Tank, Pool, Ponds, Aquariums

I bought it to pump and flush my hot water tank with and it performed flawlessly. I removed the cheap plastic drain valve on my water tank and installed a high quality full open port drain valve, and between that and this pump wow what a huge difference. Now I can flush my water tank better (sediment comes out much easier because of the higher flow) and also much faster. The bucket method took me almost an hour to drain my 40gal tank whereas now it only takes 5-7mins if that. This pump is well worth the $70 price and I love how it is a cordless battery operated pump too. I use 1 of my 20v Dewalt batteries on it. The pump also has a light on it that you can turn on or off as you wish as well. It also feels like it has a good quality build to it. Great cordless pump that you can take wherever you need it and without worrying about finding an outlet to plug in a power cord, which is another big advantage obviously. I am very happy with this pump.

This worked great for transferring water from a barrel into our RV while we were dry camping. Easy to use too. Very pleased with this purchase

I run a 250 gallon ibc tote watering plants, only issue is running it almost 2hrs straight it gets a little warm and shuts down, works great, just wish it would have came when advertised... ordered may 25th was supposed to have June 8th, didn't get until the 25th of june

ultra fast word every penny because have enough flow to made the job quick ultra cheap price with a very low nice when working I use to empty my gas tanks on my toys

At first this pump was working good. It went through one battery so i put in on the charger and switched to a second. After the second battery ran out, I went to charge it as well and noticed the first battery wasnt charging at all. I put the second battery on and the charger flashed the broken battery flashing symbol then nothing. Both batteries were drained and are unable to hold any charge at all. This machine destroyed them. It will cost me $150 to replace those batteries. This device sucks, it needed to be designed so it doesn't destroy the batteries you put in. DONT BUY THIS IT WILL DESTROY YOUR BATTERIES

Thus far I have only had it for a couple of day and it is awesome. It pumps very well, and it is not as noisy as I thought it would be. It was easy to hook up and I did not have to prime it.

We seeded a lawn area this afternoon and I was excited to start using this pump to water the area. Unfortunately, it was DOA.The light on this pump works great. Other than that, I have nothing positive to report. My pump made a few gurgling sounds, drew a little water into the supply hose, and then died. I was approximately 3' above the water source so it should have worked fine, but water never even made it to the pump. I tried three Dewalt 20v batteries, which all were fully charged and verified to function just fine in other devices. I'm hopeful that I received a bad pump and that Mellif will quickly remedy the situation via a warranty replacement.I will update this review if/when Mellif responds to the email that I sent them earlier today alerting them to this situation.**UPDATE**Customer Service came through helping me reset the pump and we are now in business. It is working great thus far.

It's nice it uses the Dewalt batteries, but it will drain a 6Ah battery in about 25 min. Additionally, the pump works but it's not that strong. It's probably worth the price but don't look for this to be a powerful pump.
