High-Flow Circular Hole PVC Drain Fitting

Experience unrestricted water flow and ultimate waste removal with our Circular Hole Drain Fittings from Atradesen.com. Manufactured from drinking-water-grade PVC, this bulkhead is specifically designed for turtle tanks, koi ponds, high-density seafood pools, and custom aquariums that require massive, clog-free drainage for large detritus.

🌊 Maximum Flow & Non-Clogging Design

Unrestricted Circular Hole: The open, grid-less design easily passes large particles and heavy turtle/fish waste without clogging, making it incredibly easy to clean and maintain.
Flush Bottom Drainage: Engineered to sit perfectly flat against the tank floor, ensuring complete water and waste removal with zero dead zones.
Versatile Switch Setup: Connect to standard PVC hard pipes via push-fit or PVC cement. Pair it with a PVC ball valve below, or simply plug the top hole with a rubber stopper for a highly effective, low-cost manual drain switch.
