Who This Is For

  • You are planning a multi-table irrigation setup because you need consistent drainage across every station to keep your nutrient solution moving.
  • You are maintaining a large-scale flood and drain system because worn fittings cause leaks that waste nutrients and create messy floors.

What We Found

  • We keep these in the shop because they seat tightly without needing extra sealant, which saves a massive amount of time during setup.
  • The reusable design holds up through multiple crop cycles, so you can pull these out for cleaning without them cracking in your hands.

What Users Say

  • Operators who stocked up on these spares say they stopped halting their drain cycles whenever an old fitting finally gave out.
  • Users who swapped to these specific fittings say they finally achieved a consistent seal that prevents leaks between the table and reservoir.

Active Aqua 3/4" Fill/Drain Fitting - Pack of 10

Flood and drain systems depend on reliable fittings to move nutrient solution between the flood table and reservoir on every cycle — and a leaking or poorly fitted drain is one of the fastest ways to lose solution, undermine timing, and create a mess in the grow room. For a complete system setup, the Active Aqua Fill/Drain Combo Kit is an excellent choice, while these individual Active Aqua 3/4" Fill/Drain Fittings are designed to seat securely in standard flood table drain ports for consistent, leak-free transfers. Sold in a pack of 10, this is a practical stock-up for multi-table operations, system builds, or keeping replacements on hand for ongoing maintenance. For larger-flow configurations requiring higher solution volume per cycle, the 1" fill/drain fitting is also available.

Features

🔩
Standard 3/4" Flood & Drain Fit

Connects flood tables to nutrient storage solutions like the Active Aqua 2.0 Black Reservoir via 3/4" tubing — a common fitting size for smaller to mid-scale setups.

💧
Leak-Free Connection

Seats securely in standard flood table drain ports, maintaining a leak-free seal throughout fill and drain cycles without additional sealants or tape.

📦
Pack of 10

Ten fittings per pack — practical for multi-table builds, commercial installations, or keeping spares on hand so system maintenance never waits on a reorder.

🔄
Reusable & Easy to Replace

Durable construction supports repeated use across grow cycles, and the straightforward fitting design makes replacement fast when components show wear.

Frequently Asked Questions

What is the difference between the 3/4" and 1" fill/drain fittings? +

The primary difference is flow capacity — the 1" fill/drain fitting moves a larger volume of nutrient solution per cycle, making it better suited for larger flood tables. The 3/4" fitting is appropriate for smaller to mid-scale tables where moderate flow is sufficient and the drain port is sized for 3/4" fittings.

What is a fill/drain fitting and how does it work in a flood and drain system? +

In a flood and drain system, fill/drain fittings are installed in the drain ports of the flood table. During a flood cycle, a reliable pump such as the Active Aqua Grow Flow Bottom-Draw Pump pushes solution up from the reservoir through the fill fitting into the table. When the pump stops, gravity drains the solution back down through the fitting and into the reservoir.

How many fittings do I need per flood table? +

Most standard flood and drain setups use two fittings per table — one for the fill line from the pump and one for the overflow/drain return to the reservoir. The pack of 10 covers up to five standard two-fitting table setups, making it well suited for multi-table grows or shared facility builds.

What tubing size do I need to use with this fitting? +

This fitting is sized for 3/4" inside diameter tubing. Using undersized tubing will restrict flow during flood cycles and slow drain times, while oversized tubing won't seat on the fitting barb securely enough to prevent leaks. Active Aqua 3/4" ID Black Vinyl Tubing is a compatible option available separately.

Is this fitting compatible with flood tables from other brands? +

The 3/4" fill/drain fitting is a standard size used across many hydroponic brands, so it will physically fit any table with a standard 3/4" drain port, such as those found on an Active Aqua 2.0 Low Rise Tray. Measure your existing drain port before ordering if you're working with a non-Active Aqua table.

How do I install a fill/drain fitting into a flood table? +

Fill/drain fittings typically install through a pre-drilled hole in the flood table bottom, with a locking nut tightened from the underside to create a watertight seal. If you need to create or enlarge a port, an Active Aqua Stepper Drill Bit provides the precision needed to ensure a clean, leak-free fit.
