I will provide a detailed explanation of the self-priming valve included with self-priming pumps!
At Yui Technology, we publish explanatory columns related to bathtubs and pools on our website. In this article, we have written about the "self-priming valve." "The water temperature of the bathtub is higher than set." "The pump might be running dry." Could it be because the self-priming valve has come off? By reading this, you might understand the cause of the mechanical malfunction. Pumps are quite complex!

basic information
...When starting a new pump, it is essential to perform "priming." This means filling the pump with water in advance to create a flow of water. So, what happens if you stop a pump that has just started working? The impeller stops, the centrifugal force disappears, the water flow ceases, and the water in the casing loses its direction and flows back to the suction inlet... As a result, the water in the casing decreases, and when you try to operate the pump again, it may not be able to create a proper water flow. However, with a "self-priming" pump, it can retain enough priming water in the casing for the next operation!!!...
