What Customers Are Saying

Customers praise the product for being simple to operate and effective for light-duty tasks like draining water or cleaning, with many highlighting the long hose and debris-avoidance features. However, a substantial portion report durability concerns, describing the shaft as bending easily, handles feeling fragile, and internal components failing after brief use. Several reviewers state they would not repurchase due to its inability to withstand moderate use. A few note it requires significant physical effort for larger volumes. Overall, most find it suitable only for occasional, gentle use.

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.

I does not work

Needed to pump water out from around my water meter. After pumping 50 or so time I only got a coffee cup full of water. Junk. I am returning.

Useful tool for home, garden, and canoe

Would Recommend

The pump works well, but care must be exercised so as not to bend the pump shaft when it is withdrawn from the pump body completely. The manufacturer would do well to supply a clip or some other means to secure the pump body to the side of the container or vessel to be emptied. The discharge force requires either holding on to the hose end or using a hose clamp to secure the discharge end. I am using the unit to move water around a straw-bale gardening project, and it works quickly and without m...

Finally figured it out.

Would Recommend

Like many other reviewers of this pump I was frustrated with it and about to take it back until I discovered that you use it with the cap on not off. The cap appears solid but it is actually perforated. The instructions say remove the cap for cleaning but it is all too easy to overlook that and assume the cap comes off for pumping. It worked satisfactorily after I put the cap back on it.

Plastic Transfer Pump

Would Recommend

Very compact and easy to use. I like the amount of water that is expelled with each pull. The pump seems to be durable for normal around the house usage like cleaning sediment out of the spa and hard to reach areas in the pool. Wish it had small fold down stand-off base so pump would be easier to hold in place while suctioning with the other hand. My spa is a bit deeper than the pump is actually built for but it does work well under water as long as the outflow is not impeded. Is there enough d...
