Main highlights

Smoothly installable: Depending on the pump and connected pool heater (whether heat pump or solar module), different flow speeds can make sense. While classic on/off bypasses hardly allow adjustment, thanks to the infinitely adjustable ball valves, you can adjust the water flow very precisely, which can noticeably improve the efficiency of your pool heating.
Safe for use: many bypasses or switches you need to assemble. Some models will leak at the beginning or over time or require the handling of aggressive adhesives. This is not the case here, as the solar switch comes in one piece from the factory and does not need to be assembled by yourself. Of course, hoses are still to be mounted by you.
Versatile and universal: you can connect both 32 mm and 38 mm hoses. The solar switch is suitable for year-round fixed installations as well as for pool setups that are only set up over a few months. Operation with salt water systems is expressly permitted.
Robust and durable: the Miganeo solar soft comes with thick inner walls and is equipped with highly durable materials at every point. For maximum durability.
Attachment: The box contents include stainless steel hose clamps for 32 mm and 38 mm. A PTFE sealing tape is also included, so that it can be sealed as much as possible.
