What Causes Recurring Drain Clogs?
Published January 15, 2026 · Astra Plumbing LLC
A drain that clogs once is usually a simple blockage. A drain that clogs again and again is telling you something deeper is wrong — grease hardened along pipe walls, a partial collapse, tree roots in the line, or a venting problem that keeps water from draining properly. Repeated store-bought drain cleaner can actually mask and worsen these underlying issues.
Plumbing problems rarely announce themselves in advance, but a little preventive attention goes a long way. Below, our team shares what we've learned from servicing thousands of homes across the Charlotte region.
