I bought these as well as new sprecta back flow protectors. These double the time and the vacuum strength in order to produce the same output. These are junk. I tested, It took me 5 mins to initiate a let down with these brand new, with spectra brand new it took 1.5 minutes to let down.Safe to say, don't cheap on pump parts.
