If only water went down a drain, clogs would be rare, but hair, soap scum, grease, and food scraps ride along with the water and collect in traps and pipe bends. These are the common mistakes when clearing a clogged drain that we still see after a home attempt goes wrong.
This restored post keeps the four mistakes from our 2021 guide and updates the advice so it is safer and easier to follow. It is not a second drain cleaning service page, and it is not our post on signs you need professional drain cleaning in Ruston. This article stays on what not to do with a plunger, a hand auger, a chemical cleaner, or a P-trap.
If water is backing up at more than one fixture, skip the home tools and call Mark Johnson & Sons Plumbing at (318) 319-0220.
Using the wrong plunger
A plunger works when it can form a seal and move water against the clog, and that only happens if you use the right shape.
A flat cup plunger is for sinks, tubs, and showers. Set it over the drain, add enough water to cover the cup, and push with steady, moderate force. Hard, frantic plunging can loosen the trap slip nuts under a sink and start a leak.
A flange plunger has an extra ring of rubber that folds out for a toilet drain, and that is the tool for a clogged toilet. A sink plunger often will not seal on a toilet, and a toilet plunger used in a sink is less effective and less sanitary if you put it back in the kitchen later. Keep them separate.
If several plunges do nothing, stop, because repeating the same motion rarely helps and can stress older fittings.
Jamming an auger down the drain
A drain auger, or snake, is meant to touch the clog, not to be forced like a rod. Feed the cable in until you feel resistance, then rotate so the head can hook or break up the blockage. Pull back slowly and see what comes with it.
Driving the cable hard can scratch the pipe, wedge the head in a fitting, or loosen a trap. If the cable will not advance, or you feel a hard stop that does not give, do not lean on it. That is the point to step back and let a technician use a machine they can control, and a camera if the line still will not clear.
A small hand auger can help with a bathroom sink or tub, and it is not the right tool for a main sewer backup. Our comparison of hydro jetting vs snaking explains when a professional cable is enough and when the line needs a jetter instead.
Using chemical drain cleaners
Many store-bought cleaners rely on harsh chemicals that generate heat or a strong reaction to dissolve a clog, and those products can damage pipes and fixtures, burn skin, and linger in a septic tank or sewer line. They also make a later visit more difficult, because a technician may have to work in a line that still holds a caustic mix.
For a light clog, a plunger is safer. Baking soda and vinegar can help with soft buildup near the opening, but they will not replace a cable on a packed clog. If you already poured a chemical cleaner and the drain is still stopped, do not add another product. Flush with plenty of water if the line is moving at all, keep people and pets away, and call a plumber.
Our guides to natural drain cleaning solutions and drain cleaners, including the biological option, cover safer first steps in more detail.
Ignoring the P-trap
Under most sinks, the pipe does not run straight down. The curved section, the P-trap, holds a little water so sewer gas does not come up through the drain. It is also the most common place for a sink clog to sit.
If plunging fails, the trap itself may be full of debris. Place a bucket underneath, loosen the slip nuts at both ends, and remove the trap. Clean it by hand or with a brush, check the short run of pipe toward the wall, and reassemble the nuts snug but not crushed. There will be water in the trap, so the bucket matters.
If the trap is clean and the sink still will not drain, the clog is farther in the wall or in a downstream line. That is no longer a homeowner trap job.
Mistakes when clearing a clogged drain in Ruston
Ruston homes, especially older houses and rentals with heavy fixture use, see a lot of clogs from hair, wipes, and kitchen grease. Mineral scale can also make a slow drain worse by giving soap film more to cling to, which we cover in our guide to how hard water affects plumbing in Louisiana. The four mistakes above are the ones that turn a short visit into a larger repair.
If you have tried the right plunger, stayed gentle with a hand auger, skipped the chemicals, and cleaned the trap, and the drain is still slow, it is time for professional drain cleaning in Ruston.
Call Mark Johnson & Sons Plumbing at (318) 319-0220 and we will clear the line and explain what we found. The main drain cleaning page also covers cable and jetting work if the clog is deeper than a sink trap.
A little caution on the first try often keeps a simple clog from becoming a loose fitting or a deeper blockage, and if those steps do not restore a steady flow, stop and let a technician finish the job.
FAQs about mistakes when clearing a clogged drain
Should I use a chemical drain cleaner on a clogged drain? It is better not to. Harsh cleaners can damage pipes, burn skin, and sit in the line if the clog does not move, which makes a later visit harder. A plunger, a cleaned P-trap, or a professional cable is a safer path.
Can snaking a drain make it worse? Yes, if you force a hand auger. The cable can scratch the pipe, wedge in a fitting, or punch a hole through grease and leave the coating in place. Feed the cable until you feel the clog, rotate gently, and stop if it will not advance.
What kind of plunger should I use? Use a flat cup plunger on sinks, tubs, and showers, and a flange plunger on a toilet. The shape has to seal so the tool can move water against the clog. Keep the two plungers separate so a toilet tool does not go back into a kitchen sink.
