I have a Tunze Ozmolaor. (Hopefully spelling is close enough so you all know what I am taking about) the pump fails about twice a week and I have to bang it a few times to get it to go. I called BRS and they said there wasn’t a different brand pump I could use with it. I find that incredibly hard to believe. So I ask you. The much smarter than me people if they have a solution other than using another tunze pump. Oh and it’s less than 6 months old.
