Zeus Plumbing provides professional drain cleaning in San Antonio for recurring clogs, slow drains and full stoppages — kitchens, bathrooms, laundry lines and main sewer lines. Our technicians diagnose the cause of the blockage, give you written pricing before work begins, and offer same-day scheduling across the city.
A drain that has been "fixed" three times this year isn't fixed. Across much of San Antonio, recurring stoppages signal failing cast-iron drain lines — original 1950s–1980s pipe corroding from the inside out. When the pattern says the line itself is failing, we tell you plainly instead of selling you a fourth cleaning.

Why San Antonio drains keep clogging
Much of San Antonio inside Loop 410 still runs on original cast-iron drain lines, and cast iron corrodes from the inside out. The rough, narrowed pipe snags everything that passes through, so clogs come back faster each time. A sewer camera inspection shows what's happening inside the line — corrosion, scale, roots or a break — before anyone talks about digging.
Tree roots are the other great San Antonio drain killer. A hairline crack or loose joint releases moisture into the soil, and roots grow toward it. Once inside, they form a mat that traps paper and waste. Hydro-jetting cuts the roots out and scours the line clean.
Grease is the most preventable cause of drain stoppages. It goes down the kitchen sink as a liquid and solidifies a few feet in, layer after layer, until the drain runs slow or stops. A snake punches a hole through the clog; hydro-jetting scrubs the pipe wall clean. Keep grease, coffee grounds, rice and "flushable" wipes out of your drains — wipes don't break down.
Drain cleaning FAQ
Hydro-jetting vs. snaking: what's the difference?
Snaking punches a hole through a blockage to restore flow — fast and effective for a simple soft clog. Hydro-jetting uses high-pressure water to scour the entire pipe interior, stripping grease, scale, sludge and roots. For recurring stoppages jetting lasts longer.
Why does the same drain keep clogging?
Because the underlying problem is still there. Most drain cleaning in San Antonio clears the blockage but can't fix corroded cast iron, roots or a broken pipe section. If you're clearing the same line every few months, a camera inspection shows whether you need another cleaning — or a repair.
Are chemical drain cleaners safe?
We recommend against them. Caustic cleaners generate heat that can damage pipes, rarely clear a real blockage, and create a chemical hazard for anyone who opens the line afterward. They can't touch roots, scale or grease. Mechanical cleaning or hydro-jetting is safer and actually clears the line.
How does a sewer camera inspection work?
A waterproof camera on a flexible rod enters the line through a cleanout while our technician watches the live feed — and you see it too. We find corrosion, roots, breaks, offsets and bellies in real time, so any repair recommendation is based on evidence, not guessing.
