The most common reason for high rate consumption of O-rings is that you have switched to non-original O-rings, with a shorter lifespan. Many people think that an O-ring is an O-ring and if it fits, all is well.
But in order to achieve a good service life, the hardness and quality of the O-ring must also be correct, and originally your AVA was supplied with O-rings from a Danish manufacturer that maintains a very high quality.
You can buy o-rings and kits in our online store.
If, despite using our O-rings, you experience a short lifespan, the next step is to inspect the groove in which the O-ring is located, as well as to check that there is no damage or unevenness where the O-ring/coupling fits.
