Leaking is definitely not normal with the cups. Your warranty covers any manufacturer defects that should arise within 60 days of purchase, but beyond that is likely due to a misuse of the product. This most often occurs when:
- The hard cup parts have not been boiled for the recommended 10 minutes
- The parts were steamed (microwave bag, dishwasher, bottle sterilizer)
- Abrasives were used (bottle brushes) or other damage has occurred
- The parts were stored in the fridge
Boiling the parts is important for two reasons:
- It sanitizes the cups before first use
- It helps mold the parts to each other making them airtight
You are welcome to boil the hard cup parts (cups, funnels, valve bases) as often as you’d like. Do not ever boil soft parts like duckbill valves, barriers, quick connectors, or tubing.
Prep parts Open-System (L), Closed-System (R)
Correct, no steaming. Freemie parts are made from a lightweight medical grade polypropylene plastic. This material is strong and durable and can withstand boiling water but is susceptible to damage from very high temperatures. Our cups can handle the temperatures water reaches at a boil, but steam can warp them causing them to leak.
Think of Freemie like your best bra. You wash it by hand. You’d never throw your best bra in with other clothes on hot right? Or, think of how plastic looks after it comes out of the dishwasher — it’s never the same again. The same is true for Freemie. Save yourself the headache and AVOID STEAM.
Treat me right!
Think about it. Freemie is not your average pump solution. You wear it. It can’t leak. It really, really can’t leak. If you scrub the parts with a scratchy sponge or bottle brush with hard bristles, the parts get scratched. If you drop them on cement, they get scratched. If you wash them with other dishes and a fork gouges just one part, you have a scratch. What happens with scratches? They cause leaking. It’s called capillary action. Avoid it.
Yes, cold blows. Why can’t they go in the fridge? Because it is super important that they don’t leak. Freemie has special benefits, and special care. Don’t treat Freemie like bottles and horns. If you put the cups in the fridge you’re asking for problems like milk backing up, valves failing, or leaking. Don’t cold store.
