Loosing vacuum from pumping breasts

[Bazooms]

I replaced my silicone rings on my cups as when I would pump, my breast would inflate a little and then I could hear the air escaping from the cup.
I changed the interlocks and when I pump my left breast, I could see it inflate and when I did my right breast it would not inflate as fast the the left one
and I had to hold the cup in certain positions for it to slowly inflate. When I got it pumped up I could hear air escaping from the cup and my right girl
would deflate some what. I Changed interlocks from the left to the right and pretty much same result. I use to be able to pump em up pretty snug
and they would hold for about 30 minutes and then I would deflate. The left one can inflate quicker then the right and as I mentioned, as of late
I would pump the right one and it was very slow to inflate and sometimes I could inflate to desired result. If I moved any, it I could hear air escape.

I just tied spreading a little vaseline on the surfaces of both siicone rings and that seems to help with the inflating process. I never had to do that before. I've been pumping regular for last couple years. I use a estrogen cream and a progesterone cream before pumping and the cups
would inflate with ease. After removing the cups, I message them some and rub some Jergens cherry almond lotion on them. I love the feminine scent.


I found on Google that using Vaseline in not good for use on Silicone rings.
So I removed it. I just wish I knew why one of the seals will not start pumping up one of my breasts.
I have to constantly pump and pump and sometime one of the two cups will start to inflate and the other
one will not no matter how fast I pump. Sometimes, when I can get one of the girls pumped, if I move a little
the air will quickly leak and partial deflation occurs. I just got the new seals today and have these issues.
Don't why this is happening......
