This topic is about dealing with leaks from the white vent on Hollister 2-piece ostomy bags, especially when lying down. The person sharing their experience is four weeks post-surgery and has noticed leaks overnight, which seem to come from the vent or filter area of the bag. They are curious if this is a common issue with Hollister bags or if they might have a faulty batch. Here are some helpful tips and insights shared by others:

1. Leaks from the vent or filter can happen if the output is loose or watery, and gas pressure builds up while lying down. To help with this, try manually "burping" the pouch often, especially before going to sleep.

2. You can cover or disable the built-in vent:
- Use 3M Transpore tape or other medical tape to cover the Hollister filter. Some people find this stops leaks.
- Consider switching to a pouch model without a vent/filter, or ask for non-vented versions of the Hollister bag you prefer.

3. For an alternative venting solution, you can install an Osto-EZ-Vent on any 1- or 2-piece pouch. This allows you to release gas easily and even rinse the bag without removing it.

4. Regular burping is still necessary because Hollister filters can clog quickly, often within a day, and stop working.

5. The consistency of your output matters. People with thicker stool rarely experience filter leaks, so you might want to explore ways to thicken your output if suitable.

6. Additional tips to prevent leaks:
- Use barrier strips or tacky skin barriers around the wafer.
- Warm the wafer/pouch with your hands, make sure your skin is dry (a hair-dryer on cool can help), and press firmly for 60 seconds to secure the seal.

7. Some cleaning routines that users find helpful include rinsing the pouch with warm water or a douche bottle after emptying, unsnapping the top of a 2-piece to wipe the flange area, and soaking spare bags in warm soapy water with a little bleach, then rinsing and air-drying them for reuse.

8. Some products mentioned by users include:
- Hollister one-piece convex pouch 53900 (noted for leak reports).
- Coloplast pouches, which several members use filter-free without leaks.
- 3M Transpore tape.
- Osto-EZ-Vent.
- StomaGoggle ostomy belt, which is a waterproof shower cover.

By using these strategies—such as taping or replacing the vent, controlling burping, applying the wafer properly, and considering optional accessories—many have found they can eliminate or greatly reduce nighttime leaks from the Hollister white vent.
