Installation Instructions: IRS Overflow Return Kit assembly instructions (PDF + step-by-step)

Aquarium and overflow box sold separately. Photos show the kit installed in a TRUVU acrylic overflow box for size and fit reference.

The TRUVU Integrated Return System (IRS) Overflow Return Plumbing Kit routes water from your sump return pump back into the aquarium through the overflow box—a clean, sealed return path for freshwater and saltwater tanks with a drilled overflow.

Pick the tubing length that matches your aquarium height (8"–30"). Each kit includes 3/4" bulkheads, hose-barb fittings, vinyl tubing, and a 3/4" directional round nozzle so you can aim return flow where you want it. Compatible with VCA Random Flow Generator nozzles as an upgrade.

Requirements: Two holes in the overflow box for 3/4" bulkheads—one in the bottom and one just below the skimming teeth. Drill diameter for those bulkheads is 1-1/2".

What’s included

  • 2 × 3/4" slip × hose barb straight fittings
  • 1 × 3/4" slip × slip bulkhead
  • 1 × 3/4" slip × hose barb elbow
  • 1 × 3/4" thread × slip bulkhead
  • 1 × 3/4" NPT connector
  • 1 × 3/4" flexible hose segment (6")
  • 1 × 3/4" round nozzle
  • 1 × length of 3/4" vinyl tubing (choose 8", 12", 16", 18", 20", 24", or 30")
  • Aquarium and overflow box not included.

Note: Extra aquarium tubing from the pump to the lower hose barb is not included. Use flexible 3/4" ID aquarium tubing for that run so pump vibration is absorbed—do not hard-plumb the full return line.

How to choose tubing length

Match the kit’s vinyl tubing length to the height of your aquarium (the vertical run inside the overflow). When in doubt, choose the next length up.

FAQ

Is this for drain or return?
Return only. It returns sump water through the overflow box; it is not an overflow drain kit.

Freshwater or saltwater?
Both. Use it on TRUVU (or other) aquariums that have an overflow box with the two required bulkhead holes.
