The 1/4 lines are underneath the equipment compartment. It's not part of the ozone system as I already capped that off
Here is the fitting I'm talking about. I circled it. The pic I showed earlier is underneath that fitting, with insulation removed.
There are two 1/4 lines coming off the 3/4 piping underneath. One goes to the drain and the other goes to the main jets pump. You can see the 1/4 bleed line going underneath from the "K" pump
