"The order was processed in a timely manner and was received when promised. I use these for my acid pump that feeds my pool. As with many things, I tend to push the pump tubes further than their recommended service life (1 year): bad idea. They must get micro cracks near the end of their service life because they leak acid onto the Pump Roller Assembly pins and deteriorate them. Hence, need a new Roller Assembly. Lesson learned: change the tubes when recommended."
