What direction should the jets in a swimming pool be pointed?
In my pool the jets all face to the right. As I see, this works well. It keeps the water flow or movement circleing the pool and moves all debris towards the skimmer and bottom drain.
The best way to position pool jets is slightly downwards (this is so the water that comes from your filter ends up at the bottom of the pool where disinfection is the strongest and then pointing in such away as to encourage a current that coincides with the skimmer that way more surface rubbish is removed before it sinks.
Best water circulation is when returns are set 45 degrees downward What to do when vortices appear that defeat the skimmer?
The best way to beat this problem is to replace the return jets with a ninety degree setup that had a larger opening than the eyes that you find in the return jets. these can still be pointed downwards, along the wall of the pool and give very good control over the direction of the pools currents, which in turn gives you more control over the skimming.
