How often do you....

[Ruth]

Your supposed to pull them apart and clean them? Go figure??? Really I clean my tunze's about once a month and I'm with Christy when things don't sound right on my main pumps. I have a backup pump for all of my waterpumps (return, closed loop, and skimmer) but only because of where I live and having no LFS within reasonable driving distance. I even have backup smaller tunzes incase these go down so in the event of a pump failure from my um extended timeline between cleaning I can replace easily.
