The Laguna Pressure-Flo is a sealed pressurized filter. The installed O-rings provide water tight seals in 4 locations. If damaged or missing, the unit would leak. The O-Rings in your Pressure-Flo Filter won't last forever and eventually will need to be replaced. The O-Rings are located in:
1. Lid

2. UVC Head or transformer
3. Quartz sleeve (x2)

4. Each Click-fit Connector

We can start with the Fittings. These are located inside the click-fit connection port and are an orange/red color so they're hard to miss. Next, we can move onto the UVC head. This O-Ring is located on the underside here. While we have the UVC out and upside down, we can replace the two on the quartz sleeve. These are located at the base of the sleeve behind under retaining flange. To access, pull the sleeve straight up after the flange is removed.
After all these are replaced we can remove the filter lid and replace the filter lid O-Ring. The filter lid O-Ring is positioned inside the top of the filter canister recess. (replace)
