    slotted jet...why?

    my pool has three returns. two of the returns are the standard eyeball type return/jets, however one of them is a slotted jet with minimal flow. What is the purpose of having this type of jet? I would like to replace it with a standard one. the other two jets push out a lot of water, very strong current.

    Is it there to more accurately direct the flow of water into an area of decreased circulation such as close to steps, a corner, downward in a deep end or such?

    Re: slotted jet...why?

    When you say slotted are you talking about one of these venturi jets http://www.infusionpool.com/ If so they help in the mixing of water, I have one installed in my deep end to help prevent cold water settling there as I don't have a floor drain and this venturi jet shoots water down deeper than a conventional eyeball.

    no, it looks like this: http://www.poolzoom.com/hayward-hydr...d-sp1419a.html

    and its the jet on the opposite side of the steps, on one of the more flat areas of the pool on the shallow end. there is minimal flow coming out of it, but it is directionalized.

    As you can see, those fittings are easily interchangeable so try anything you like. That slot looks to me like it is intended to send water in one direction only and it makes sense that it has less volume than the others if they are conventional "eyeball" fittings

    Re: slotted jet...why?

    I use regular eyeballs on some of my returns, but installed slotted ones in a couple of locations where I wanted the flow to be parallel to the pool wall. That helped me direct floating debris towards the skimmer. I don't have a flow problem with the slotted ones though, so I don't understand what you are experiencing.
