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

Why the right part matters
Guessing on parts vs the correct foot valve
A check valve is a small part with an important job. Getting the right one, in the right size, keeps your aeration system priming quickly and keeps water out of the airline.
Going without or improvising
No check valve or a mismatched part
- Water backs up the airline every time the compressor cycles off
- Without a check valve, the system has to re-prime instead of restarting quickly
- A generic or wrong-size fitting may not match your airline
- Water sitting in the line works against the compressor it should protect
