I always check for the little tears by the nub and i always see tiny holes. So I toss them and buy new ones. </p> https://boards.hellobee.com/topic/medela-pisa-membranes#post-455607 Wed, 19 Dec 2012 12:45:55 +0000 winniebee 455607@https://boards.hellobee.com/ <p>I only changed them when I lost them (down the drain sometimes when I cleaned them!) </p> https://boards.hellobee.com/topic/medela-pisa-membranes#post-455594 Wed, 19 Dec 2012 12:43:09 +0000 Weagle 455594@https://boards.hellobee.com/ <p>Hmm... I've been using mine about 6 months and have never changed them. Maybe I should! </p> https://boards.hellobee.com/topic/medela-pisa-membranes#post-455554 Wed, 19 Dec 2012 12:33:43 +0000 mamabolt 455554@https://boards.hellobee.com/ <p>I never have? Been using my pump regularly for three months now. </p> https://boards.hellobee.com/topic/medela-pisa-membranes#post-455546 Wed, 19 Dec 2012 12:32:23 +0000 purrpletulips 455546@https://boards.hellobee.com/ <p>I used a Lansinoh pump with DD and don't recall ever changing the membranes. I am using a PISA this time and have been pumping 3x/day for about 2 months and noticed a decline in how much I was pumping so today I put in new membranes and pumped more milk. If you have a PISA how often do you change the little white membranes? </p>
