Installing the valve correctly

Match the connection size and fit the valve in the marked direction of flow. Allow access for inspection because debris can prevent a non-return valve from sealing. Check that the valve's opening resistance is appropriate for the selected pump and installation.

Our practical advice: If you are unsure about sizing or compatibility, send us the Aquascape part numbers you already have and a photograph or sketch of the installation. We will help check the combination before dispatch.
