Details
The Foot Valve is a small part with an important job. It is a one-way check valve installed at the diffuser end of your airline that lets air flow down to the pond but stops water from backing up the line when your compressor cycles off. That protects your compressor and keeps the system priming quickly every time it restarts.
Why it helps
- One-way valve that prevents water backflow into the airline
- Helps protect your compressor and speeds restarts
- Available in 3/8 inch and 1/2 inch to match your airline
Choose the size that matches your airline.

Why it matters
An airline with a foot valve vs. one without
When a pond aeration compressor cycles off, water can climb back up the airline. Here is what changes once a one-way check valve is in place.
Without a foot valve
Water backs up the line
- Pond water can flow back up the airline when the compressor stops
- The compressor works harder to re-prime and push air on restart
- Standing water in the line slows the system every time it cycles
With the Koenders Foot Valve
One-way airflow, protected compressor
- Air flows down to the pond while water is stopped from backing up
- Helps protect your compressor from water sitting in the line
- The system primes quickly and restarts every time it cycles
What the Foot Valve does
A small part with an important job
Installed at the diffuser end of your airline, the Foot Valve keeps air moving in one direction so your aeration system runs the way it should.
Protects your compressor
By stopping pond water from backing up the airline when the compressor cycles off, the valve helps keep water out of the line and away from the compressor.
One-way airflow
The valve lets air flow down to the pond but blocks water from travelling back up the line, so the airline stays clear.
Faster, cleaner restarts
With water kept out of the line, the system primes quickly and gets back to aerating every time the compressor restarts.
Sized to match your airline
Choose 3/8 inch or 1/2 inch to fit the airline you already run, so the valve seats correctly at the diffuser end.
