In-Line Water Level Controllers

Control water levels in ponds, lakes and wildlife habitats

In-Line units provide great stability, access and resistance to debris.

In-Line Level Controllers have both inlet and outlet pipe connections.

Stoplogs slide in tracks within the unit to regulate the water level.

The box is buried with the the top rising above the soil surface.

Our DrainBox in-line water level controllers are great for maintaining water levels in habitats and ponds.  

Key features include:

  • Durability: Heavy-duty welded aluminum

  • Rugged and Robust:   Easily withstands normal field installation practices.

  • Easy Installation: Just bury it and forget it. Backfilling with an excavator is acceptable.

  • User-Friendly Design: Straightforward intuitive operation.

  • Low Maintenance:  Does not require routine attention.

  • Versatility: Suitable for various applications – ponds, hunting habits, agricultural settings, retention impoundments, aquaculture, or industrial processes.

  • Fabricated in the USA

Installation of your in-line water level controller is simple! 

  1. Prepare the Trench
    Start by digging a trench from the bottom of the pond or habitat. Ensure it's deep enough to accommodate the pipe and provide a stable path for water flow.

  2. Locate the Control Box Area
    Identify the optimal location for the water level control box. Position it where access is convenient for maintenance and monitoring.

  3. Attach PVC Pipe
    Securely attach either Schedule 40 or SDR 35 PVC pipe to the flexible couplings included in your kit. Ensure the connections are tight and leak-free.

  4. Bury the Controller and Pipe
    Bury the controller and pipe, avoiding rocks and large clumps of soil that could exert excessive pressure on the system. The aluminum control boxes are very durable. Backfilling with an excavator is acceptable. Stoplogs do not need to be in place during installation.

Follow these steps, and you’ll have your water level control system up and running in no time.

Relocation — These units are tough enough to be relocated if necessary. Carefully dig on each side of the unit to access the pipe connections. Loosen the clamps and pull the unit out of the ground using a strap.

Stop Logs

Push the stop logs into the slots on each side of the water level control box.   The rubber seals are designed to fit snuggly in place with just enough clearance to slide easily in the slots.    A T-handle tool is provided to push and pull the stop logs within the slots.   Place all of the boards into the water level control box then pull up on the board at the desired water level.  This will open a gap in the wall of stop logs for the water to flow.   The bottom of the box lid indicates how much gap is needed to achieve full flow (this is dependent on the pipe and box diameters).

The heavy-duty metal construction makes the control box resistant to crushing.  It is not necessary to install the stop logs in place before the water box is installed.

The rubber seals are good but not perfect.   Some slight seepage is normal. 

 

Lockable Lid

A lockable lid is provided.   The lid is intended to keep wildlife out, deter tampering and prevent children from dropping debris into the box.   The lid also provides a safety measure to keep someone from accidentally stepping into the box or a pet from falling into the box.
