nozzles

[mariobrothersleeve]

Where do you get return line nozzles from. Does anyone just have the pipe return w/o nozzles?

I dont use nozzles. Just use a couple 45s on a T to direct the flow where I want.

Did you drill a hole for sphion break or running a back flow preventer? Any positives for either?

Some sort of system to break the back flow is pretty critical, if you were to lose power you dont want a bunch of tank draining down into the sumer causing it to overflow

Sorry my question was worded wrong lf, i was wondering if slime of some sort would build up on the orifice on the back flow preventor causung failure or drilling a hole would cause splatter outside of the tank. What would be the pros or cons to these?

I have two holes drilled in my return just below the water line. Why two? well If a snail is on one when I have a power outage then I have a back up and hope the snail didnt bring a friend. Just below the water line also makes it where I have no splashing. I know some people use back flow preventers but then they still dill a hole just below the water line as a back up because they can fail.

i put a check valve on my pvc so no back draining
