I know this is in an old post, but where did you find this pump for only $260? I am seeing it listed around $700 everywhere now. We've already had this pump rep;aced once in 2018. Full time now and it's acting up again. Wants to keep running after flushing. Yes, I can stop it with turning it off by switch (we have two toilets so still need the VacuFlush), but I fear the pump is failing yet again!
