GREAT little pump for the camper
Willee✓ Verified Purchase•August 17, 2017
GREAT little pump for the camper!!! I had to purchase a plastic ell to get it to work but this was NOT a fault of the Seaflo pump. It was replacing the original pump from my 1986 Scotty. Make sure that you put a switch in the power line to shut the pump off if needed. We have been leaving the sink faucet open and using the switch to turn the water on and off. This should save some wear and tear on the faucet gasket. That sounds kind of picky but I am a miser to the nth degree. I would highly recommend this pump!!!
Works great.

Works great. Have a year on it in my camper. Still pumping no problem. Don't expect more that 1gpm which is what it's rated for. But I like the low volume as I don't waste water.
Very easy to hook up. Great pressure.

Installed one of these in a camper I was restoring. Hooked it to the water tank easily and ran power to it through a rocker switch. When turned on it immediately gets to pressure and shuts off. Used quite a few times now and has been great! When the tank goes dry it does not continuously run it will shut down to not burn out the pump. Great feature!

I decided to add a water source to my tailgate trailer and ordered a 10 gallon water tank, this pump, clear braided nylon tubing and a table with a sink and faucet. The pump is located within a foot of the water tank and the table with faucet is 8 feet away. This pump does a great job of getting a decent water flow to my faucet. I'm very satisfied with this pump.
Such an awesome little gadget, works well and quality is very good - well worth the purchase

Such an awesome little gadget - I use it to pump water from my rain water tank through a hose into my garden - I found there was not enough water pressure so this little pump certainly did the job! I had to go on utube to get some directions on how to install as I am not a handy-woman, but was pretty simple once I worked it out! thanks v much - awesome!
