    UPVC Dual-Function Standpipe Overflow & Bottom Flush Bulkhead Fitting

    Designed for commercial seafood holding tanks, aquaculture breeding racks, and marine aquarium sumps, this heavy-duty UPVC bulkhead fitting from Atradesen.com delivers both reliable water level maintenance and high-volume bottom sludge draining. Featuring a precision slip-in top standpipe socket and a high-flow flat bottom drain plate, it enables effortless tank flushing with zero stagnant residual water.

    ⚠️ CRITICAL TANK THICKNESS & SIZING SPECIFICATIONS:
    • Wall Thickness Requirement: SUITABLE ONLY FOR GLASS/TANK WALL THICKNESS OF 10mm OR GREATER. Do not install on thin-walled tanks (<10mm) as the gasket will not compress properly.
    • Dual-Diameter Engineering: Bottom Socket glues directly to your main drain line using PVC solvent cement; Top Socket accepts a matching-diameter vertical standpipe (friction-fit) to establish water depth.
    • Instant Water Level Adjustment: Insert a vertical pipe to set overflow height; pull the standpipe out for rapid, full-bore bottom flushing without tools.

    Key Engineering Features

    • True Flush Drain (Zero Residual Water): The low-profile slotted base sits flush against the tank floor, completely purging bottom debris and sludge without leaving dirty puddles.
    • Heavy-Duty Commercial Seal: Engineered with an extra-thick silicone sealing gasket and reinforced threaded union ring, resisting leaks under constant aquatic head pressure.
    • Anti-Clog Slotted Strainer Cap: Top protective cross-grate prevents fish, shellfish, and large stones from falling into the drainage main.
    • Potable Water Grade UPVC: 100% resistant to marine saltwater, aquaculture chemicals, and organic waste with zero harmful plasticizer contamination.

    Common Applications

    Perfect for seafood restaurant market tanks, multi-tier hatchery rack drainage, fish farm overflow standpipes, turtle tank purge sumps, and commercial hydroponic flood-and-drain reservoirs.
