Overview

AW WSP50LF Solar Rated Non Return One Way Check Valve is spring loaded and designed to prevent the high-temperature backflow from the roof collectors present in solar hot water systems. In order to survive this high temperature working environment, the AW check valves are constructed with lead free DR brass body, silicone seals and high temperature rated full brass internals.

During the operation of solar hot water systems in summer, a stagnation condition can be created as the storage water tank reaches its maximum top out temperature usually around 60-70 degrees. In such stagnant conditions, the solar pump will stop water circulation and the solar roof collectors can reach 180°C in flat plate panels and 200+°C in evacuated tubes. This super heated water remains in liquid form due to the pressure in the solar hot water system and pushes down back to the water tank creating the backflow. This back flow can cause damages to the water pumps, flow meter and other components if not prevented. A standard check valve that is not solar rated will melt over time with the usual plastic internal components. A swing type check valve would create excessive flow resistance and poor seal. The AW WSP50LF spring loaded solar rated check valve is perfect in such installations, offering minimal pressure drop during water pump operation and long lasting seal even in continuous high temperature environment.

The AW solar check valves can be installed in either vertical or horizontal orientations and is WaterMark Approved for compliance in Australia. The solar rated check valves can be also used in low temperature rating steam applications.

Good filters. Good value!
I ordered this Uselection brand Cabin + Engine air filter set for my 2017 Honda CR-V 1.5L vehicle. These filters are sturdy and well-constructed. The cabin air filter contains activated carbon to absorb odors and isn't thin and flimsy like other brands. Both filters fit and seal very well. This is a convenient and economical 2-filter set, as both filters get replaced at basically the same one-year interval. I recommend this filter set.

Fit my 2018 CRV 1.5 turbo
I’m not a car expert, my maintenance expertise involves air in the tires, adding oil and washer fluid, and these filters. Found a video to show me how, it was easy. These fit my car, and I don’t see any difference in these and the filters they replaced, except of course, these are cleaner. Very happy.
