A couple of weeks ago I had the wetside and dryside on one of my Mp40s randomly fall off, the dry side falling into my kalk reservoir. Luckily after a quick rinse in RODI and a rice soak for a week it's working just fine but I want a more failsafe way to keep the dryside from falling (the stickers that come with the pumps do not work). Has anyone come up with a solution for this?
