Drain problems don't warn you. They just stop working.

Grease, soap scum, and debris don't accumulate overnight they build up over months and years. By the time you notice a slow drain, you're already close to a full blockage. Kitchen drains are especially prone to grease buildup that coats the inside of pipes until almost nothing gets through.

Neglected drain maintenance is the most preventable plumbing problem in any home. A professional cleaning once a year costs far less than emergency service when a drain fails completely or when a backed-up sewer line damages your floors or walls. O5 Plumbing keeps your drains clear with professional-grade equipment and no-nonsense flat-rate pricing.

Slow Draining

Water pooling in your sink or shower is the first sign. Don't ignore it it only gets worse from here.

Gurgling Sounds

Gurgling after you flush or drain is air trapped in a partially blocked pipe. It means water can't flow freely.

Bad Odors

Foul smells from drains indicate organic buildup or sewer gas intrusion both need immediate attention.

Recurring Clogs

If the same drain keeps clogging, store-bought products aren't solving the real problem. You need a professional clearing.

What San Antonio Homeowners Say

"Our kitchen drain had been sluggish for months. I kept pouring stuff down it and nothing worked. O5 came out the same day I called, cleared the line completely, and explained exactly what had built up. No upsell, no drama. The current offer made it even better."

Marcus T., Northeast San Antonio

"Sump pump died during a heavy rain. I called O5 at 7am and they were there by noon. The tech explained what failed, showed me the part, and had a new pump running before evening. Straightforward pricing, no games. These guys are the real deal."

Debra W., Leon Valley

"Camera inspection saved us from a big mistake. We were about to buy a house and O5 scoped the sewer line found root intrusion that the seller didn't disclose. That inspection paid for itself ten times over. Highly recommend before any home purchase."

Jason R., Alamo Heights

Common Drain & Pump Questions

Straight answers no jargon.

No chemical drain cleaners damage your pipes over time. Repeated use corrodes metal pipes, degrades PVC and plastic fittings, and can crack older porcelain fixtures. They also rarely clear the full blockage, which means the clog returns quickly. A licensed plumber clears the problem completely without destroying the pipes in the process.

Slow drains are usually caused by bacteria, soap scum, mineral scale, or grease buildup along the pipe walls. In bathrooms, hair and soap combine to form a sticky mass that narrows the pipe gradually. In kitchens, cooking grease is the primary culprit. We diagnose the exact cause and clear it properly not just punch a hole through the blockage.

For most homes, once a year is the right interval for main line and kitchen drain cleaning. Bathrooms in heavy-use homes may benefit from more frequent service. If you have older cast iron lines, a tree-heavy yard, or have already had root intrusion, more regular maintenance and camera inspections are worth the investment.

Stick to soft foods: fruit scraps, cooked vegetables, and small food particles. Avoid fats, oils, and grease they solidify in the pipe downstream. Also avoid coffee grounds, egg shells, fibrous items like celery or corn husks, pasta, rice, and anything starchy or expandable. When in doubt, throw it in the trash.

Watch for unusual grinding or rattling noises, a pump that runs constantly even in dry weather, visible rust or corrosion on the unit, or a motor that cycles on and off rapidly. If your pump is 7-10 years old, it's worth having it inspected even if it seems to be working sump pump failure during heavy rain is one of the most damaging plumbing emergencies a homeowner faces.

Stop a slow drain before it becomes an emergency.
