I purchased the Kuri Tec Backwash Hose, Extra Heavy Duty Industrial Grade 1 1/2 inch, because the regular soft blue backwash hose kept getting holes and splitting and is a pain in the butt to get the water out after backwashing.
So I decided to try the industrial type hose. Best money spent and decision ever! It’s like a tarp type material and not as delicate as the regular blue hose. To get the water out of the hose is also much easier to do. I purchase 100ft at $0.99/ft. You can buy any amount you want, doesn’t have to be 100ft. I highly recommend this hose.
