[ Home > Koi pond pumps > Pond Pump Check Valves ]

Pond check valves prevent water from flowing back down the pipe if you remove the pond pump.

Our aquascape check valves are most common if you have a Aquascape classic or signature series skimmer filters.

The most common reason to replace a check valve is because the inner flap has become dislodge slowing down the flow from your koi pond pump.

Some PVC glue may be required to assemble your new check valve depending on your koi pond pump and skimmer set up. All the check valves shown below are shipped not glued together, this makes it easy to adjust to your particular pump and filter set up.
