Don’t Ruin Your Plumbing with Sourdough Discard - Call MasterCraft Plumbing

When you rinse sourdough starter or discard down your sink, it doesn’t just wash away like soap or water. Instead:


  • It’s sticky and glue-like. Flour mixed with water creates a paste that can harden quickly in pipes.
  • It expands over time. Just like bread dough rises, starter in your pipes can expand and block water flow.
  • It clings to grease and debris. Sourdough discard easily sticks to oils and food particles, making clogs form faster.
  • It doesn’t break down easily. Unlike many food scraps, flour-based mixtures can harden and stay lodged inside your pipes.


Over time, even a little discard here and there can turn into a stubborn clog, especially in older pipes commonly found in homes around Jefferson and Commerce.


How to Safely Handle Sourdough Discard


To avoid plumbing headaches, follow these simple tips when dealing with sourdough starter and discard:


  1. Never pour it down the sink. Treat discard like dough in that if you wouldn’t put raw dough in your drain, don’t put starter there either.
  2. Use the trash can. Scrape discard into the garbage or compost it if you have a bin.
  3. Rinse tools into a bowl first. Let bowls and utensils soak in a container, then scrape solids into the trash before washing. You can also wipe utensils completely with a paper towel and just throw away the paper towel.
  4. Compost instead of disposing. If you garden, sourdough discard makes great compost material.
  5. Use it in recipes. Many bakers reuse discard for pancakes, crackers, or pizza dough, reducing waste and preventing plumbing issues. Here is a link to a great sourdough pancake recipe: https://www.youtube.com/watch?v=oMeOPxqIiUQ


By following these tips, you’ll save yourself from clogged drains and costly repairs.
