General Pool FAQ’s

Why are the eyeballs (jets) different sizes?

The eyeballs differ in size to produce various pressures. The ¾” eyeball will produce more pressure from the nozzle than the 1” eyeball, however, it does not move as much water. The larger the opening, the more water will flow.
Note: The smaller the eyeball the harder the pump will have to work and the harder the pump has to work, the shorter its life.

Can I change the pool light bulb myself and how do I change it?

We recommend having someone experienced with changing the light bulb change it for you, however many homeowners are able to change the light bulb themselves. Please remember that this is an electrical product in water and every precaution should be taken. The 2 most important things to remember, if you decide to change the light bulb are to turn off all power to the pool before you start and make sure you put the light back together properly.
