Handcrafted in USA Handcrafted in USA No. You do not need a Bypass Valve on your Smoky Lake Filter Press.
Many of our competitors use brass gear pumps, also known as “positive displacement” pumps. These pumps are less forgiving and can build up dangerous pressure which needs to be relieved by a bypass valve for safe operation.
In contrast, the Smoky Lake Air Diaphragm Pump offers ultimate control of pressures and pump speeds and does NOT require a bypass valve to relieve pressure. Smoky Lake offers either a hand pump or a stainless steel air diaphragm pump which have a longer lifespan, are easier to use, and are manufactured using superior food grade materials.
Furthermore, Smoky Lake Filter Presses with Air Diaphragm Pumps have a T-valve which allows you to transfer liquids from one place to another without filtering. This is also sometimes referred to as a “bypass”, but it’s purpose is not for relieving pressure. It is just a handy tool for transferring syrup or sap from one place to another. For more information on T-Valves, see our article “How To Operate A T-Valve”.
