By-Pass and Manifold Information

Pump Water By-Pass

Submersible Pump Water By-Pass

Increase the size of your submersible pump, install a "Tee" and "Ball Valve" Manifold to create a secondary by-pass line for additional circulation; use ball valves that can adjust water flow in either direction. Installing a Tadpole Filter on the pump's suction will increase the performance and operating life of the pump.

UV Water By-Pass

UV By-Pass

Create an easy-to-install, water by-pass to divert a precise flow to the UV Sterilizer; based upon its recommended flow rate. To improve accuracy, install a Water Flow Meter (shown below) between the ports. Adjusting the UV Sterilizer 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

External Pump Suction Manifold

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