Recurring drain clogs are not just bad luck — they usually point to an underlying problem. Here are the most common causes in Nampa homes.
If your drains keep clogging despite regular cleaning, the problem is not just what you are putting down the drain — it is likely something structural about your plumbing system. Recurring clogs in Nampa homes often have one of several root causes that liquid drain cleaners and basic snaking cannot permanently fix.
Pipe scale and buildup is the most common culprit. In Nampa, where water hardness is significant, mineral deposits accumulate on the inside walls of drain pipes over years of use. This narrows the pipe diameter and creates rough surfaces that catch hair, grease, and debris more easily. Professional hydro-jetting can remove this buildup completely.
Older homes in Nampa may have cast iron or galvanized steel drain pipes that have corroded internally. Corrosion creates rough, pitted surfaces inside the pipe that catch debris and cause chronic clogs. In severe cases, the pipe walls have deteriorated enough that replacement is the only real solution.
Improper pipe slope is another cause of recurring clogs. Drain pipes need to slope at a specific angle to allow waste to flow freely. If a pipe has settled, shifted, or was installed incorrectly, waste accumulates in low spots and causes repeated blockages in the same location.
