Sewer aerator 50mm

thingiverse

I was compelled to create an air valve for my sewer system because when water is drained into the toilet, a vacuum occurs in the collector. Instead of buying an aerator at the store, I decided to make one myself due to laziness, as usual. The design turned out to be quite simple. To minimize support, I divided the model and assembled it without glue by twisting the entire structure along the thread, with the exception of the diaphragm valve. Initially, I thought a plastic ring would suffice, but the uneven surface lacked the necessary density of fit. As a result, printing was unnecessary, and using it as a template for cutting out a ring from plastic film proved convenient. I glued the membrane with elastic glue along its outer radius. The outcome is an air valve that effectively allows air to enter the sewer while preventing it from escaping. Additionally, this design operates in any position, unlike traditional factory models. To be honest, I don't particularly like my design. Please don't judge it too harshly. However, I hope this device will be useful to someone else.
