Old breastpump insight?

Al

So, I had my first baby in Feb 2017 and insurance gave me a Medela Pump In Style Advanced. Loved it, used it a lot. For this baby, I plan on using the same pump because my insurance only covers a new one every 3 years. Has anyone done this before? My biggest fear is that I’ll buy new pieces and everything and then the pump will quit working or something since it’s old and I used it a lot previously. Just wanted to hear from other moms. I’m not against buying a new one but I’d like to skip that if I can 😂
