5.3 Attach the Gravel Guard Collar and Dome
Once the base is securely installed and connected to the drainage pipe, attach the gravel guard collar. This collar clamps to the drain base using a twist-and-lock mechanism, providing an additional layer of protection against debris.
Finally, place the UV-stable ABS dome onto the collar. The dome's design allows for a free-flow area while preventing larger debris from entering the drainage system.

6. Operation
The Oatey 78044 PVC Roof Drain operates passively to remove rainwater from roof surfaces. Its primary function is to collect water and direct it into the connected drainage system, preventing water accumulation on the roof.
The dome acts as a protective barrier, allowing water to pass through while effectively blocking leaves, twigs, and other large debris that could clog the drain pipe. The design ensures a continuous flow of water, even during heavy rainfall, by maintaining a significant free-flow area.
7. Maintenance
Regular maintenance is crucial to ensure the long-term efficiency and performance of your Oatey 78044 PVC Roof Drain.
- Periodic Inspection: Inspect the drain dome and surrounding area at least twice a year, or more frequently during seasons with heavy foliage or storms.
- Debris Removal: Clear any accumulated leaves, twigs, dirt, or other debris from the dome and the drain opening. This can be done manually or with a soft brush.
- Check for Damage: Examine the dome and drain base for any signs of cracks, damage, or wear. Replace components if necessary.
- Ensure Proper Sealing: Verify that the seal between the drain base and the roofing material remains intact to prevent leaks.
Note: Always exercise caution when working on a roof. If you are uncomfortable performing maintenance, consult a qualified professional.

| Problem | Possible Cause | Solution |
