Hi there,
I cannot seem to remove the yellow valve (with the white flap) from the bottom of my pump. It just wont come off, and I'm sure it needs changing. I have some spare, and nowhere does it say how I can remove the valve. It wont twist off. I'm stuck.......
Also, I wash my pump after each use, very thoroughly, and sterilise it, yet it seems to have some residue on the inside bit, where the bottle brush can't reach. What to do?
Thanks in advance.
