Replacing pump parts

[CurlsAndDimples]

Hi all, bub is 11 months old and I’m still breast feeding. I pump once a day, in the evening before bed as he sleeps through the night and it means I’m not too uncomfortable by the morning. I was using one Elvie pump and then a few months in purchased a second so I could do both breasts simultaneously and save time. The new pump came with new pump parts and the amount I was expressing doubled, showing me the importance of changing the duckbills and pump seals. The time has come to change the parts again as my supply has gone down but they are so expensive to replace the whole time! Does anyone know of generic parts I could buy that are cheaper but compatible with the elvie?
thanks in advance

You say that you're pumping so you're not uncomfortable over night, but you don't have to do that. Your body is used to producing milk because you pump, but if you stop that it will settle very quickly (maybe just hand express a little for a few days to transition).

If you want to pump to give a bottle that's different, but if it's just for your comfort the cheapest solution is to stop!

I give the odd bottle here and there so would like to continue my evening pump.
