Submersible Pump By-Pass

Up-size your submersible pump. Install a "Tee" and "Ball Valve" Manifold to create a secondary by-pass line for additional circulation. Use PVC Ball Valves that can adjust water flow in either direction. Installing a pre-filter (Tadpole) on the pump's suction will increase the performance and operating life of the pump.

UV By-Pass

Create an easy-to-install UV by-pass to divert a precise water flow to the UV based upon its recommended flow rate. To improve accuracy, install a Water Flow Meter (shown below) between the ports. Adjusting the UV by-pass requires establishing a "Full Flow" rate. After identifying the "Full Flow" rate (without by-passing water) you can adjust the by-pass (first 3-Way Valve) to achieve the desired flow. The secondary valve is either closed (no by-pass) or fully opened while by-pass is in operation.

External Pump Suction Manifold

Use a 2" 3-Way Valve (#OV#-2010U) as a manifold to join the surface skimmer with the bottom drain. In this diagram we substitute our large Tadpole (#01705) for the bottom drain. This arrangement eliminates the need for cutting the liner. Instead, the Tadpole is pulled from the pond for easy cleaning.
