    Cool My Poor Boy Aerator

    Just snapped a bunch of PVC I had hanging around in the garage.

    Guess I'll need to pick up a 45 (for now using a 45 abs - which is that black piece)

    Inspired by Rangeball's aerator (which is much slicker I must say)

    Has anyone tried to create a venturi version?

    Re: My Poor Boy Aerator

    A venturi version could be possible, with a little bit of modification of a few fittings.

    What comes to mind quickest is a 1-1/2" tee, with a 1/2" or 3/4" side inlet. grind out the stop shelf inside the side inlet, so you can push the 1/2" or 3/4" all the way into the flow area. Cut the small pipe at about a 45* angle before you glue it in, with the open end of the pipe towards the outlet.

    Might work, but you will have to experiment a bit to get it right.

    Yup - tried using an ABS Y Pipe shooting straight into pool with and extension that pointed back to jet. I then used an extended 8" piece with a plug and a 3/4" braided hose to feed air down to the flow.

    I get some suction but it is minimal and it is really picky about where that braided hose end sits in the flow and angle. So it's not consistently delivering air.

    Re: My Poor Boy Aerator

    Another version I might try:

    Basically a T-Pipe with a 3/4 in feed that is held in place by a plug and then be able to rotate the 3/4 feed pipe with the end in the stream cut at 45.

    A venturi will work better if you restrict the main water line (like an hour glass) in order to increase velocity.
    T an air line in the narrowed section.
    Velocity will increase and pressure will drop through the narrowed section of tubing, in turn drawing more atmospheric pressure air into the T line.
    Note. Make the narrow section of water pipe as short as possible to reduce friction flow losses.

    Re: My Poor Boy Aerator

    Maybe more like this?

    1 1/2" to a 1" reducer, 1" T pipe and back to a 1 1/2"

    Will the reduction be enough?

    If you know the approximate flow rate, you can use Bernoulli's equation to find the pressure difference.

    http://www.efunda.com/formulae/fluid..._flowmeter.cfm

    But my guess is that it needs to be much narrower. A spa jet is maximum about 7/16" orifice for a 1 1/2" pipe. Why not just use a spa jet venturi tee?

    Actually never thought of that....

    Re: My Poor Boy Aerator

    BTW, with the venturi tee, the entire setup can be left underwater with only the air pipe sticking above water level. You can then make it so it will not stick out much from the pool wall. Less of a chance someone will hit it.

    Like Mas says, if you have a spa jet with a smooth tapered reducer it would be better than the rough squared edged T fittings you have in the drawing.
    The length and angle of the taper makes a difference. It is most important to have a smooth taper to reduce eddies.

    My Poor Boy Aerator

    This is what we did last year to cool our water when it got got tub like. Not the same problem this year. Aeration does raise your ph though. Hard to see but laterals have small holes drilled in them on an angle that puts water out at a 45 degree angle to water line. And no that overgrown weed field is not mine😊. .

    Re: My Poor Boy Aerator

    Thank you mas985 and bdex

    I'll take a look at the venturi Tee as an option
