Does anyone know why there is a lot of air bubbles coming out of my in-ground pool water jets. Will it damage anything?
Thanks..

It could mean that you have a pump that is to powerful for the lines or you have a suction leak, does the pool lose any water?

It probably will not damage anything but this sounds like you have a crack or leak in one or more of your intake lines. As the pump pulls water toward the filter its pulling poutside air into the line due to suction. In this case your filter and circulation will be less efficient

If you have a 1hp or more motor on a 1 1/2 line it will cause the pump to cavitate, or you could have a partially clogged impeller, check all of you orings and drain plugs on the motor to make sure they are in good shape if not replace them with new ones and lube them up with something called magic lube
