Upgrade your overflow system or create a simple manual drain with our Premium PVC Dual-Level Water Plug. Installed directly onto your overflow weir glass or water tank, this clever bulkhead allows you to easily switch to a lower water level simply by unscrewing the cap—draining excess water without needing a bulky, expensive ball valve. Manufactured from high-quality, durable PVC, it provides incredible strength and a permanent watertight seal for both freshwater and marine tanks.

Why Choose Our Dual-Level Plug?

• Dual-Level Overflow Control: Perfect for sump overflows and water holding vats. Remove the threaded plug to instantly lower the water level during maintenance, feeding, or adjustments, saving you significant plumbing space.
• Premium PVC Construction: Molded from robust, aquarium-safe PVC material that resists cracking, high water pressure, and degradation over time, ensuring a safe and leak-proof installation.
• Versatile Clamping & Sizing: Models A and B securely clamp onto glass up to 15mm thick. Model C handles ultra-thick glass up to 25mm (the external plastic threads can be easily sawed shorter for a flush fit on thinner walls).

⚠️ Installation Guide: Installation requires a pre-drilled hole in your glass or acrylic panel. Carefully match your drilled hole aperture (ranging from 20mm up to 60mm) to the correct model variant. Always ensure the rubber sealing gaskets are positioned correctly on the wet side before tightening the back nut to guarantee a secure, leak-free seal.
