This topic is about finding cost-effective alternatives to disposable ostomy pouch liners. The idea is to use biodegradable dog-waste bags instead of commercial flushable liners, which can be more expensive. Here’s how it works and some advice to consider:

1. The suggested method involves using biodegradable dog-waste bags, which cost about 1.5 cents each, compared to roughly 20 cents for branded liners. For those using two-piece systems connected to municipal sewers (not septic tanks), you can cut off the bag’s tie handles, stretch the open end over the pouch opening, snap the pouch in place, and flush the filled liner when it’s time to empty. A fresh bag is then inserted, eliminating the need to rinse or replace the outer pouch.

2. The originator of this idea has used this method successfully for five years on a city sewer system and emphasizes that it should not be used with septic systems.

3. Plumbing and flushing concerns are important to consider. Former sewer-line technicians advise that anything other than the “3 Ps” (pee, poo, paper) can cause blockages and backups, especially in low-flow toilets. To avoid issues, it’s recommended to always double-flush and run extra water. Treating roots with products like “Robux Root Destroyer” or using periodic salt flushes can also help.

4. Liners have their advantages. They allow some colostomates to wear one wafer for about 10 days while using only two outer pouches. Even with 15-20 liners at about 30 cents each, this method can be more cost-effective than using extra pouches and reduces cleaning time. Commercial liners with built-in vents can improve odor control by allowing gas to escape without stool leakage.

5. When comparing products, Colo-Majic disposable liners receive positive reviews for their fit and venting. However, dog-waste bags from dollar stores are slightly thicker, which might prevent a secure snap between Hollister wafers and pouches, risking accidental separation. These bags, along with UK “nappy sacks,” can be used as cheap disposal sacks for used pouches or liners but are not universally trusted for flushing.

6. Practical tips include only attempting the dog-bag method on reliable municipal sewer lines and avoiding septic systems. It’s important to test the fit carefully on your specific two-piece system (e.g., Hollister) to ensure the added material does not interfere with the pouch-to-wafer connection. If the snaps won’t engage, it’s best to revert to purpose-made liners like Colo-Majic.
