Good, Just Not What We Needed

Would Recommend

We needed to pump some water out of the crawl space and this wouldn't fit in the space, so we had to return it. But it looks useful for other purposes.

Great Product and Fast for a hand pump!

Would Recommend

This week was the coldest that the Chicagoland has seen in 20plus years. I needed a pump to transfer Diesel Fuel into another truck. I went everywhere in my area and bought small pumps but it was to cold to use those. I landed at Lowes and stumbled across this pump i figured I didnt have much to lose at this point. All I have to say is I was impressed. The length of the pump and the hose were incrediable. I was able to drain the fuel and transfer it to another truck with honestly very little ef...

Works great once I discovered you need the cap on

Would Recommend

Works great once I discovered you need the cap on. I have to admit I didn't figure that out by myself. After being unhappy that I couldn't get it to work I started reading reviews. Fortunately one of the reviewers was kind enough to inform us of that. I bet I wasn't the only one though that didn't figure that out myself.

Handles broke in 15 minutes, TWICE!

Would Not Recommend

This pump has great potential. It pumps a large amount of water quickly. However, the T-handle snapped off after about 15 minutes. Lowes replaced the first pump with another when I explained what happened. Then the second pump's handle also broke off after about 10 minutes of use. I am a small woman and I was not using excessive force. I was able to continue the pumping job by gripping the shaft with rubber gloves, but a functioning handle would have made the job much easier.

Constant pumping required to transfer liquid. Wish it would hold a syphon after flow starts.

Compliments your upper body workout!

Would Recommend

It works great! I needed something to move some scummy water out of a deep container and it pumped the water out along with debris that had accumulated in the water without any problem. I was afraid some other models which had smaller outlet tubes than the intake tube might end up with some of the debris getting caught, but I didn't have this problem. I also liked that the tube was longer (6.5 feet long) than some other models that I looked at so it could transfer the water over some other obs...

Broke in 15 minutes

Would Not Recommend

What a pile of garbage. Like many plumbing problems this was bought for an emergency. No needless to say I was not happy when the top T handle broke off about 5 minutes into pumping, 20 minutes after I bought it. On the way to return it now. I'm a big dude but I cant imagine I was pumping any harder than anyone else would in an emergency.

Boat pump

Would Recommend

Utilize this hand pump as a secondary pump to remove water from bilge on my boat. This unit is light weight. Easy to assemble and to operate. The discharge hose is extra long. Making it useable on boat free boards.

Voting for Corsan!

Would Recommend

Bought this 'just in case'. . . 'just in case arrived with two days of heavy rain. The level of water in one well window was almost dangerous. This light weight, simple to use tool became worth its weight in gold. Saved the day.
