Things You'll Need
Fiber supplements help people with digestive problems move waste through their body more efficiently. These products are designed to provide bulk to your waste and help unclog your digestive system. However, when spilled down the sink they tend to add bulk to the drain and cause a serious clog. Unclogging a psyllium fiber build-up in your drain may be more difficult than unclogging normal drain issues but you can take many similar steps.
Flush the drain with hot water as much as possible. Since psyllium fiber is designed to dissolve in warm liquids this should help dissolve some of the drain. Leave hot water in the drain until it completely flows down the drain. Continue to flush drain with hot water for about one hour.
Mix equal parts baking soda and white vinegar in a small dish and pour it into the drain. Allow this mixture to sit for a few hours or overnight then flush with hot water.
Use a plumbing snake to try to pull the drain to the surface.
Pour liquid plumber down the drain following instructions on the back of the bottle. Typically you will want to pour half of the bottle down the drain and allow it to sit for thirty minutes. Then flush the drain with warm water.
If problem still persists, repeat all steps.
Make sure the water you use is not too hot as this can cause damage to pipes.
