Comments: Cobalt multi-purpose pump is a very good inexpensvie pump. I am in the plumbing business and I checked around to find a better price and a pump local. The only local pumps to do the gpm and head pressure I needed were double in price. The pump I use is in a 6ft head water fall and it does a superior job and is small enough to lay in the base of the water fall.

Comments: This is the third MJ Powerhead I have purchased over the last 10 years. They do a good job for the money. I would give a 5 star rating if they were more solidly built.

"As always my experience with Marine Depot was 'overall satisfaction.' If on the phone, by video or the write-in reviews on the product I am interested in, they are always helpful. When I am in doubt of what product will help me or where to find it, Marine Depot is usually the first and last place I go to."
