New Users

For new users, feeling little to no suction can be due to a number of reasons such as incorrect cup assembly, poor bra or breast flange fit, or use with an incompatible pump. 


  • Check that your pump connection has been properly assembled. The Y-connector part holds 3 lengths of tubing. One end connects to your compatible pump, the other two connect to the cups. 
  • One pump port should always be capped closed for both single and double pumping.

  • Check that cups have been properly assembled. Assemble clean, dry parts just before use. 
  • Barriers should be placed into the valve base.
  • Be sure that the flaps of the tongue-shaped barriers are not tucked inside the valve base. 
  • The valve base and barrier should then be pressed onto the mounting ridge of the breast flange very firmly.

Experienced Users

If you are an experienced user successfully using Freemie Standard Cups and have only recently started to lose suction, check the following: 


Valves

Worn out valves can cause a loss of suction and should be replaced every 2-3 months for best performance. Replace sooner if use is heavy.


Barriers

Tongue-shaped barriers are durable but but can become damaged. Inspect barriers under a bright light. Uncurl the edges and squeeze open to look for any damage. Replace if damaged. Find the Slimfit5 barriers, here. Find the Slimfit6 barriers, here. Watch this video for barrier inspection details.

Pump Connection

If you had milk back up (check barriers) and be sure that the tubing and Y-connector are not clogged with any dried milk. Replacements can be found here. Soiled tubing that won't come clean should be replaced. Ensure Y-connector securely holds 3 tubing pieces.


Damage

Check all parts for any damage. Cup parts should fit snugly together. If the valve base is loose on a breast flange it should be re-boiled to "tighten" parts and replaced if boiling does not resolve issue. New valve bases for the Slimfit5 can be found here and valve bases for the Slimfit6 can be found here.


Size Changes

Tissue changes over time and many moms do go down in size once lactation is established. If your pump has suction and you can see the barriers moving inside the cups when the pump is set to maximum, and you've checked all of the above, then you probably need a new size. Fitmie insert sizes 15mm-28mm can be found here.
