Emergency Overflow Outlet Pipework 32 mm/16 mm with ball valve

Ideally, in sufficiently dimensioned overflow wells, in addition to the main drainage hole (usually 42 mm bore for 32 mm feedthroughs or 55 mm bore holes for 40 mm feedthroughs), there is an additional bore as an emergency drain to prevent clogging ( eg by snails) to prevent overflowing of the skin aquarium. With the drain piping with integrated emergency drain pipe presented here, the o.g. Safety aspect can be realized even with only one existing hole in the overflow shaft.

Functional principle: Below the tank feed-through, the 32 mm drain pipe is split with a 90 ° T piece. In the vertically downward pointing outlet sits a firmly bonded or sealed with Teflon tape reduction 32/16 mm (here, the inner counter ring in the reduction from our side drilled out, so that a 16 mm PVC pipe can be completely durchgesteck). Due to the reduction, a 16 mm PVC pipe is inserted from below through the T-piece and into the overlying 32 mm drain pipe and pulled up into the drainage shaft of the aquarium to approx. 1-1.5 cm below the top of the shaft / comb. After the exact positioning of the 16 mm tube, it must be glued in the reduction or sealed tightly and securely with Teflon tape. The water in the overflow shaft runs through the 32 mm pipe in normal operation and accumulates in the T-piece at the sealed reduction and then flows through the lateral (horizontal) outlet of the T-piece into the filter tank. Clogged the 32 mm drain pipe, it inevitably leads to an increase in the water level in the overflow shaft. Total blockade would overflow the aquarium. Thanks to the integrated 16 mm emergency overflow pipe, water can nevertheless drain through the 16 mm pipe into the filter tank in the drain piping presented here.
