Active Aqua Extension Fitting, 1", Pack of 10

Set the Right Flood Depth for Taller Containers

Standard fill/drain fittings set a fixed flood height — fine for shallow trays, but a problem the moment you switch to taller pots or containers that need a deeper soak.

Active Aqua's 1" Extension Fitting stacks onto a standard fill/drain fitting to raise the flood level inside the table, so the solution reaches further up taller containers before it drains back out.

Because flood depth has a direct effect on how evenly roots get soaked, this small adjustment can be the difference between a table that waters every container fully and one that leaves the tallest pots dry at the base.

Key Features & Benefits

• Raises flood/drain level for taller containers — lets growers adjust flood depth to match container height instead of being locked into one fixed level.
• Sized for 1" fittings and tubing — fits directly onto Active Aqua's standard fill/drain fittings without adapters.
• Pack of 10 — covers multiple tables or container changes, and keeps spares on hand for fast adjustments.
• Simple stack-on installation — attaches directly to an existing fitting in seconds, with no tools or system changes required.
• Built for repeated flood cycles — holds up to the constant fill-and-drain rhythm of an active flood table.
• Works with standard flood tables — fits into layouts growers are already running without a redesign.

Who Should Use the Extension Fitting

This fitting is for flood-and-drain growers switching to taller containers, anyone fine-tuning flood depth across a table of mixed pot sizes, and commercial operations that want a simple way to standardize watering depth as crops and container choices change.

Dialing In Flood Depth

Stack one or more extension fittings onto your existing fill/drain fitting until the flood level reaches roughly two-thirds up the height of your containers — deep enough to wet the root zone fully without submerging the crown. Test a single table first, since the right number of extensions depends on container height, table depth, and how saturated you want the medium to get before draining.

Frequently Asked Questions

How does this fitting change my flood depth?

It stacks on top of your existing fill/drain fitting, raising the point where solution begins to drain back out — which raises the overall flood level inside the table.

Will this work with my current fittings?

Yes — it's sized to match standard 1" fill/drain fittings and tubing, so it attaches directly without adapters.

Can I stack more than one extension?

Many growers do, stacking extensions until the flood level matches their container height — it's a simple way to fine-tune depth without buying a different fitting size.

How many come in a pack?

Each pack includes 10 extension fittings, enough to adjust several tables or keep spares on hand as your container sizes change.

Is installation difficult?

No — it simply stacks onto your existing fitting by hand, so most growers can adjust flood depth in just a few minutes.
