Sewer aerator 50mm
Description
There was a need to create an air valve for the sewer, since when water is drained into the toilet, a vacuum occurs in the sewer collector. I could have bought such an aerator in the store, but I was too lazy to look for it, as usual, and decided to make it myself. The design was quite simple. I divided the model so that there was a minimum of support. Everything can be assembled without glue by twisting the entire structure along the thread, with the exception of the diaphragm valve. At first I thought that a plastic ring would be enough, but the uneven surface did not give the necessary density of fit. Therefore, it is not necessary to print it, but it is convenient to use it as a template for cutting out a ring from a plastic film.I glued the membrane with elastic glue along the outer radius. The result is a sufficiently sealed air valve that allows air to enter the sewer, but not letting it out. Also, from the positive aspects, it turned out that now, unlike the usual factory design, the valve works in any position. To be honest, I don't really like the design myself. Therefore, please do not judge strictly. But I hope that the device will be useful to someone.
