I installed new eyeballs in my pool outlets a few days ago, and I wondered which direction I should be setting them to direct the incoming water. They swivel 360 so there must be a reason for this. Don't know if it matters, but there are two of them on the long side of the pool and my pool is 20x42 with depths of 3' to 8.5'.

I've configured all of mine to point in the same direction, so as to encourage a swirling motion to the water. Not sure if that's necessarily "correct", though.

I have mine aimed at my skimmer....

Mine are all in the same direction as well giving my pool that counter clock-wise swirl everything passes the skimmer that way.

The way you guys have it all makes sense for regular round, oval & rectangle pools...
I would be interested in hearing from some people with "odd" shaped pools too :)

I have a lazy " L" shape & I don't know if this is the correct placement or not but everything seems to be moving well:
In the shallow end I have a universal straight piece sticking out about 2"... so this ends up actually pushing water into the middle of the deep-end when the pool-devil pro isn't attached... when the devil is attached, it brings the returned water up to the surface and pushes it along the side of the shallow end...

In the deep-end I have the eyeball pointed down & to the opposite side of the skimmer... The skimmer is about 4 feet from this eyeball. The pool is 12' deep & so I'm trying to get the heated water, ( we have a heat pump), to the bottom of the pool.

This may not be the best config, but it seems to be working well. I don't have heat spots & the bottom of the deep end seems to be the same temperature as the surface.
The "floaties" are getting skimmed out. particularly by the pool devil...( which is awesome & I highly recommend it if you have tree debris problems); some debris gets stuck around the ladders, but I suspect that's normal. Over-all I'd say the water movement is good

Thanks for all your input. I now have my 'eyes' pointed in the same direction and have a clockwise water flow. But I must say I was fascinated with the Pool Devil. Did a Google on it and found the manufacturers site - which I thought was really well done with videos and graphics. Think I'll get one since it's so reasonably priced and I do have a seed/insect/pollen problem. Another successful ending for the Pool Forum!

Your supposed to have counter-clockwise flow in North America. I don't know why, that's what PB told me. "Flush your toilet and see which way the water goes" was his explaination. Same theory - what ever that is. Maybe spinning of the earth, gravitational pull of moon - don't know. The toilet example was enough for me.

It makes sense to me not to fight Mother Nature - so today I switch them to counter-clockwise. Thanks for all your input.

That, my internet friends, is Hogwash.

Direction of circulated water in a swimming pool is at the owners discretion, what he offered is only applicable to water draining naturally. pool water is pumped under pressure and can be sent to the spot of your choice.
Some good directions are not to fight prevailing winds because the debris your pushing upwind will be pushed back towards the wall fitting, if your pushing towards a skimmer less than 15 feet away aim it slightly lower than the skimmer so you don't blow the debris past the skimmer, and if the skimmer is further away aim the return up towards the surface to get good action pushing the debris towards the skimmer.

raven,
Your best bet would be to open the main drain completely and close your skimmers each to about a quarter of their fully open position. Aim your eyeballs down towards the floor and slightly in the direction of the skimmers. Doing this will allow you to draw more water from the deepend and replace it with the warmer water from your equipment.

See Ya,
Kelly

I have an hourglass shaped pool and both my returns are in the shallow end on opposiite walls. I have them pointed in the same direction which causes a a counter clockwise circualtion in the shallow end (keeps my steps clear of dirt) and also causes a clockwise direction circulation in the deep end. I have my main drain and simmer 50/50 and only get a little dirt in the pool to the right of the main drain that I have to vacumn about every 3 or 4 weeks. It took a bit of experiemting to come up with this but it seems to produce the best results in my pool. The eyeball that is going across the steps is pointed downward and the one that goes toward the deep is aimed higher, but not high enough to ripple the surface. This causes enough circulation to keep the swim ledge in the deep end clear of dirt.
I experiemented with different settings of the main drain and skimmer and found that in my pool the 50/50 setting kept the pool clean for the longest time.
