Grodan Dutch Leach Tray Elbow, Bag of 25

Route Dutch Leach Drain Lines Around Corners Without Leaks

A Dutch Leach tray system depends on drain lines that route cleanly around benches, support posts, and wall penetrations, and forcing a straight fitting into one of those turns is a common point of failure in a new build. The Grodan Dutch Leach Tray Elbow is engineered specifically for the Dutch Leach tray system, connecting drain sections through a directional change without the leaks or kinks a mismatched part can introduce.

Sold 25 to a bag, this pack covers the elbow count a mid-size to full tray layout typically needs in a single order, with enough left over to keep spares on hand for repairs.

Key Features & Benefits

• Purpose-matched to the Dutch Leach tray system — fits the system it was designed for rather than forcing a generic part into the job.
• Elbow geometry for directional changes — routes drain lines through corners and transitions without the leak points a forced straight run can create.
• Sold 25 to a bag — covers a layout of real size in one purchase, with spares left over for repairs or later expansion.
• Consistent spec across the bag — every elbow matches the same fitting spec, so there's no sorting through mismatched parts mid-build.
• Single-purpose part — does one job — connecting and redirecting drain lines — without added complexity.

Who Should Use This Tray Elbow Fitting

This fitting suits anyone building, expanding, or maintaining a Dutch Leach tray system who needs elbow connectors that match the system spec, particularly growers running larger layouts with several directional changes to plan for.

About Grodan

Grodan has manufactured engineered stone wool growing media since pioneering the technology in 1969, and today operates as part of the ROCKWOOL Group. Alongside its rockwool blocks and slabs, Grodan supplies system components like this tray elbow so growers running Dutch Leach layouts can source matched fittings from the same manufacturer as their growing media.

Frequently Asked Questions

What system is this fitting built for?

It's purpose-matched to the Dutch Leach tray system, engineered to fit the spec that system's drain lines are built around. Using a generic elbow instead can leave gaps at the joint that lead to leaks over time.

How many elbows come in a bag?

Each bag includes 25 elbow fittings, enough to cover a build of real size or to keep spares on hand for future repairs. Ordering by the bag also keeps every elbow in a layout consistent to the same spec.

When do I need an elbow instead of a straight connector?

Anywhere a drain line changes direction — around a corner, through a wall, or between tray sections — an elbow routes that turn cleanly. A straight fitting forced into a bend is far more likely to kink or leak at the joint.

Can I use this with a different tray brand?

It's matched specifically to the Dutch Leach tray system, so check your system's fitting spec before substituting it into a different setup. Mixing fitting standards is one of the more common causes of leaks at drain joints.

Is it worth ordering extra elbows?

Many growers do, since a cracked or worn fitting found mid-build or mid-season is far easier to swap when a spare is already on the shelf. A bag of 25 typically leaves several spares even after a full layout is fitted.
