Good price and good product
Color: Black2
Work perfectly fine exactly what I want for my water supply tank.

Great pump! A couple updates to get it dialed in.
Color: Black3
Hooked it to a cabin wall to run off a 12 volt battery charged by solar. Had to get it as the last one of a different brand died after six months. This one works so good and so quiet!! I’m impressed!! Update. After just a short time running it, it is intermittently running and no leaks anywhere. Annoying because this will just burn it up quick. This part is very unimpressive. Update. Just dialed the pressure switch down and it stopped it’s intermittent running. I’m still so impressed at how quiet this pump is! ... show more

Water finally
Color: White2
We purchased this to use with our 275 gallon rains barrels. It puts out plenty of pressure to water the flower and vegetable garden. Love that when you stop squeezing the nozzle it shuts off so not to burn out the motor. Easy to connect our hoses. Comes with everything you need to connect hoses. Would recomend this for sure. ... show more

avoid this pump
Color: Black1
Bought because of the affordable price. Lasted less than a month. I'll be buying a better quality pump to replace this cheap hunk of crap. This company has contacted me and has offered to send a new pump with upgraded pressure switch if I pay for shipping. I informed them I considered that to be VERY poor customer service. Quality companies ship a new pump with a PREPAID return label for the old pump. I'll wait a few days and see how they respond. As of now, I stand by my bad review of this worthless pump. Update......they sent a replacement pump, free and did not want me to return the old pump. I installed the new pump and it worked properly for the 2 days I was at the campsite. As soon as I'm able to go and stay for a longer period of time I will give another update, For now the pump is working properly and the company does stand behind their product. I raised my rating to 4 stars for the good customer service provided by them. ... show more

Crapped out after 4 months.
Color: Black2
No longer works. Attempted to find manufacturer warranty, and all I get is caught in trouble shooting loops that solve nothing. Very disappointing.

Excellent product
Color: White2
I’ve been using this pump for nine months. It works great has excellent protection from running dry being that it is a wafer pump. This is performed and lasted longer than $160 pump. I bought from tractor supply. Highly recommend buying two of them.
