    Eyeball Orientation

    Hey Gang,

    I was wondering if you guys had any advice. I've observed weak flow from my return jets, and dead spots on the more aggresively curved areas of the pool. The following is my pool:

    natural-spring-600x447.jpg
    Red circles are my skimmers (alpha / beta) and floor drains.
    Green circles are my returns.

    Not listed on the diagram is the following:
    A. Extra swimout across from Alpha skimmer close to return 1
    B. Swimout and main steps each have 2 spinning returns, one on each side
    C. Return jets are 3/8" eyeballs in the pool. Steps/swimout have some other return w/ 2 holes that spins, so I don't know what size it is.

    This brings my total return count to 10 with 2 skimmers and 2 main drains. Pool is 6' deep at the floor drains, 3' deep at the main steps.

    I was supposed to get 6 returns in total; 4 in the pool and one each in the steps and swim-out. I ended up with 10 (don't ask I don't know). The pump is the same HP that they quoted for the 6 returns (2hp) except now I have 4 extra returns to push water through. I've observed that my water velocity is predictably on the weaker side.

    In a attempt to rectify the situation, I have gotten screw in plugs and closed off returns 2 and 5. I've pointed the remaining jets to spin the water counter-clockwise with the jets pointed slightly down from straight/level.

    I have much greater velocity now coming out of the pool jets and the stairs/swim-out steps. I feel like this is closer to the design that the builder sold me, and the velocity of my jets seems to agree.

    What do you guys think? Did I do something stupid, or is this worth the experiment. I have not seen my pressure gauge move at all on my filter since I plugged the 2 center returns. I'm hoping the greater velocity will help move more water than the way I had it w/ weaker velocity yet more returns. Oh, the prevailing wind blows towards the Alpha skimmer.

    If you want to use all of your returns and increase the velocity, you can buy eyeballs with smaller holes through them.

    Work with the wind. Stuff on the surface will be affected more by the breeze/wind. Use that to your advantage. Is the skimmer down wind or up wind? Get the wind and the flow of the water to bring stuff to the skimmer basket. Clockwise or Counterclockwise it doesn't matter use what works, but don't fight the predominate wind. Are you able to adjust your flow (suction) so it sucks more from the skimmers than the bottom?

    Re: Eyeball Orientation

    Yes I can:

    Turn off one skimmer or the other
    Turn off the floor drains independent of the skimmers

    Skimmer beta doesn't get the same amount of junk in it that skimmer alpha does - I suspect as you imply that it is because of the wind.

    If you can reduce the flow through the floor drains, it will increase the flow through the skimmer baskets. I wouldn't totally close it, but reduce it and see if it helps with skimming.

    Re: Eyeball Orientation

    I will give it a shot; is there any obvious gotchas with closing off the 2 returns that i did? I mean, I'm obviously going to have to see how it goes but I can't see how 4 in the pool and 4 in both steps can't be enough .... ???

    Re: Eyeball Orientation

    Another option would be to reinstall all the returns and slow the stairs/swim-out to a trickle via the valve in my plumbing. Thoughts?

    The important thing to remember is you do not have water flow through a pipe, alge will like that stagnant water. A low flow rate is better than no flow.

    Re: Eyeball Orientation

    Okay, so my revised way of trickling the swimouts/steps and going more or less full bore on the pool returns seems the way to go.
