Plumbing Concealment Tower/Column

Plumbing Concealment Tower/Column Details

SKU: plumbing-concealment-tower-3-pvc-tube Category:


This unique aquarium plumbing concealment tower is a perfect way to use the H2Overflow® and Siphon Stopper® on the inside of an island tank where hanging them off of the back is not an option. It is very popular with our hexagon fish tanks. The tower can fit 1 H2Overflow® and 2 Siphon Stoppers®. The inside of the tower remains dry, meaning no long-term maintenance headaches or noise issues like most traditional in-tank overflows.

When purchased with our H2Overflow overflow and 1/2″ or 3/4″ Siphon Stopper return(s) (sold separately), holes for attaching these are drilled to a standard configuration. The concealment column may also be purchased undrilled for custom applications.


  • (1) Schedule 80 PVC bulkhead for the bottom of the tank.
  • (1) 3″ PVC tube. Choose a height from a minimum of 14 inches up to 60 inches. Custom heights are also available.
  • (1) Top cap housing for returns and overflow.

*Does not include H2Overflow® overflow, Siphon Stopper® returns, tubing, or plumbing fittings.

Contact our sales team for further details. We would love to explain more and help you design the island tank of your dreams today! Also it works great for rimless frag tanks!
