Backyard Aquaponics
A place to discuss aquaponics

ball valve is similar to a faucet in function it lets you stop the flow of water. But of different construction than a faucet. Head height is the height to which the water is to be pump in your case you said five feet. But it is generally measured from the surface of the water you are pumping water from.

I know the difference between the two. What I am trying to get at is head height and using a ball valve to reduce flow would both create back pressure, thus raising amperage, and reducing pump life. correct?

Go back a few post. It was explained by Mr.Damage with diagram.
