Why the Splashguard Container Set Earns Its Place in Your Pump Bag
The Willow Sync Splashguard Container Set (2-pack) is a simple accessory that can make a real difference when you're pumping away from home. Each container is designed to help keep milk where it belongs—inside—so you're not dealing with leaks or wasted milk during a session. The set gives you two containers, so you can have one in use and one clean and ready.
But to get the most from this set, you need to assemble it correctly, use it consistently, and replace it on schedule. This guide walks you through those steps using the facts we have, and flags where the supplied information leaves gaps so you can make an informed decision.
Assembling Your Willow Sync Container Set
The supplied records don't include a step-by-step assembly diagram, but the product is a container set with a splashguard, and the general approach for wearable pump containers applies. Follow these steps carefully, and check the container for any signs of wear before each use.
- Inspect the parts: Lay out both containers and any splashguard components. Look for cracks, cloudiness, or residue that could compromise the seal.
- Seat the splashguard: Press the splashguard firmly into the container opening until it sits flush. A loose guard is a common cause of spills.
- Attach to your pump: Connect the container to your Willow Sync pump according to the pump's instructions. Make sure the connection is snug and straight.
- Test the seal: Before pumping, give the container a gentle shake over a sink to check for leaks. If you see drips, reseat the splashguard and try again.
Using the Containers to Prevent Spills During Pumping
Once assembled, the splashguard container set helps contain milk even if you move around or bend over during a session. Keep the container upright as much as possible, and avoid overfilling—leave a little headspace so milk doesn't slosh into the guard's vents. If you're using the set as spare containers, label them with the date and time of pumping so you can rotate your stash properly.
Remember that no container is spill-proof if it's not seated correctly. Take an extra second to check the seal every time you attach it.
Replacement Schedule and Care
- Willow Sync Splashguard Container Set (2-pack): For optimal output, replace every 90 days (or when you notice discomfort or signs of wear). Worn containers or splashguards can lead to leaks and spills. Marking your calendar for a 90-day replacement keeps your setup reliable and hygienic.

Cleaning Your Splashguard Container Set
The supplied records don't specify cleaning instructions for this set, so follow the general guidelines for your Willow pump parts and the cleaning advice from your pump's manual. Here are safe practices that apply to most breast pump containers:
- Rinse immediately after use: Rinse with cool water to remove milk residue before it dries.
- Wash with warm, soapy water: Use a mild dish soap and a dedicated bottle brush. Avoid harsh chemicals.
- Sanitize as needed: Follow your pump manufacturer's sanitizing recommendations—typically boiling or steam sterilization for parts that contact milk.
- Air dry completely: Place parts on a clean drying rack with good airflow. Store only when fully dry to prevent mold.
When to Rotate in Your Spare Containers
Having two containers means you can always have one ready while the other is being cleaned or is in the diaper bag. A simple rotation: after each pumping session, empty the used container, rinse it, and set it aside for washing. Grab the clean spare for your next session. At the end of the day, wash and dry both. This cycle keeps you from being caught without a clean container—and reduces the temptation to reuse a container that hasn't been properly cleaned.
What the Supplied Information Doesn't Cover
The product record for the Willow Sync Splashguard Container Set does not include detailed assembly diagrams, specific cleaning temperatures, or compatibility with pump models beyond the Willow Sync. If you need those specifics, check the Willow Sync pump manual or contact Willow support. The absence of that information here doesn't mean the product lacks those instructions—just that they aren't part of the supplied data.
Also note that the catalog price is shown as USD 17.50, with a comparison price of USD 34.99. Prices can change, so verify at checkout.
