Pouring Cooking Grease Down Kitchen Drains

Hot oil resembles liquid water when poured into the sink, but it invariably clings to pipe interiors as it cools. Once solidified, grease hardens and coats the surface, creating a tenacious trap for anything else flowing through. Think about the last time you made bacon or fried chicken – that golden grease might look harmless flowing down your drain, but it’s actually setting up camp in your pipes like an unwelcome house guest.
Cooking oil, fat, or grease may seem like liquids when poured, but they solidify and congeal as they cool, creating blockages within the pipes. These blockages can cause clogs, backups, and even damage to your plumbing system, leading to costly repairs. The worst part? Families typically discover the damage only when the drain slows and water begins to pool. Collecting leftover grease in a jar or disposable container presents a superior alternative, since even minimal daily quantities poured down the sink can amass into a dense layer necessitating professional removal.
Flushing Non-Toilet Paper Items Down Toilets

Baby wipes, facial wipes and even products labeled “flushable” do not disintegrate the same way as toilet paper. Over time, these products can cause serious plumbing issues. The clogs and backups can result in expensive plumbing bills for your home and increased wastewater fees from your community. Your toilet isn’t a magical portal that makes everything disappear – it’s more like a very specific garbage disposal that only accepts three things.
The only three things you can safely flush down the toilet into the sewer system are the three Ps – pee, poop and (toilet) paper. Nothing else. Modern households often treat toilets like trash cans, but items like paper towels, feminine hygiene products, food, toys, jewelry, and other foreign objects are not designed to break down easily. When these items are flushed down the toilet, they can accumulate and create clogs within the pipes. These clogs can cause backups, leading to wastewater not being able to flow properly, potentially resulting in sewage flooding into homes or causing damage to the sewage system.
Using Excessive Chemical Drain Cleaners

Most drain cleaners contain powerful chemicals. If you use drain cleaner too often, it can eat away and damage your pipes. Those bright blue bottles promising instant results are basically liquid fire for your plumbing system. Sure, they’ll blast through that hair clog, but they’re also slowly dissolving the very pipes they’re supposed to help.
Most commercial products rely on highly alkaline compounds, particularly sodium hydroxide, to break through blockages. While effective at dissolving organic matter, these chemicals operate at pH levels that damage pipe materials over time. Research by corrosion engineers shows repeated exposure to high-pH cleaning solutions creates microscopic pitting in metal pipes, progressively weakening pipe walls and eventually leading to leaks requiring expensive replacement. PVC pipes face different risks from commercial cleaners. The exothermic reactions these chemicals produce generate significant heat – sometimes enough to soften PVC and compromise glued joints.
Pouring Boiling Water Down Plastic Pipes

While copper, iron and galvanized steel pipes can withstand high water temperatures, materials like PVC, Pex and CPVC show signs of damage over time. And since most homes today have PVC pipes installed under kitchen sinks, any licensed plumber will advise against using boiling water to unclog a clogged drain pipe. That pasta water might seem like a harmless way to clear your drain, but it’s actually waging a slow war against your plumbing.
PVC pipes are probably the most widely used plastic in plumbing, but prolonged exposure to boiling water can soften and distort them. Prolonged contact with boiling water may cause PVC pipes to lose their shape, leading to potential leaks or blockages. It’s essential to note that PVC is designed for a maximum service temperature of about 140 degrees, and prolonged exposure to temperatures above this limit (boiling water is typically around 212 degrees) can compromise its structural integrity. PVC pipes cannot withstand water temperatures up to 100 degrees C. So if you regularly expose your kitchen pipe to boiling water, the joints (which are usually held together with glue) will only soften or melt. Over time, water pipes deteriorate and begin to leak, requiring immediate repair or replacement.
Ignoring Small Leaks and Drips

A small drip can quickly turn into a significant leak that requires a major repair. The sooner you fix the leak, the lower your risk of sustaining a lot of damage to your plumbing and property. That tiny drip under your bathroom sink might seem like background music to your daily routine, but it’s actually your plumbing system’s cry for help.
Cabinets beneath sinks frequently contain cleaning products or storage bins, allowing leaks to remain undetected for extended durations. Damp areas within these cabinets foster mold growth, attract pests, and degrade wood. Even a minor drip from a loose joint can incur substantial repair costs if overlooked. The sneaky thing about small leaks is they’re masters of disguise, hiding behind cabinet doors and under appliances while slowly destroying your home’s foundation. Regularly inspecting these concealed areas helps identify problems at their nascent stage. Replacing a loose seal or tightening a fitting proves straightforward when addressed promptly. Families incorporating this into routine cleaning habits circumvent major complications from undetected water damage.
Leaving Standing Water on Bathroom Floors

Allowing water to stand on the bathroom floor for extended periods can damage the plumbing system components that are located underground. The moisture can seep into the floor, walls, and other structures, potentially causing rot, corrosion, and other forms of damage. Your bathroom floor might look waterproof, but it’s more like a sponge wearing a disguise.
Every puddle left behind after your shower is slowly infiltrating the hidden spaces beneath your feet. Allowing water to stand on the bathroom floor for extended periods can damage the plumbing system components that are located underground. The moisture can seep into the floor, walls, and other structures, potentially causing rot, corrosion, and other forms of damage. This can result in costly repairs and renovations. The damage happens so gradually that most homeowners don’t notice until they’re dealing with warped floorboards or mysterious musty smells.
Neglecting Water Heater Maintenance

Water heaters operate discreetly until sediment begins accumulating at the tank’s base. This buildup diminishes efficiency, compelling the heater to expend more energy. Ultimately, this can result in leaks. Your water heater is like that reliable friend who never complains – until one day they’re calling you at three in the morning with an emergency.
Whether it’s a lack of hot water, strange noises, or a leaking tank, water heater problems can be a major inconvenience. These issues are often caused by a buildup of sediment in the tank or a faulty thermostat. Regular maintenance and flushing the tank can help prevent these problems. The sediment that builds up in your water heater isn’t just reducing efficiency – it’s creating tiny abrasive particles that wear down the tank from the inside. Think of it like having sand in your engine; everything keeps running until suddenly it doesn’t.
Skipping Regular Toilet Flushing

In addition, not flushing can cause waste and toilet paper to build up in your pipes, leading to blockages and clogs. If your plumbing system has older pipes, the acidic nature of urine can accelerate corrosion, making it more prone to leaks or even pipe failure. Regular flushing helps prevent these issues and keeps your plumbing system in good condition. The “if it’s yellow, let it mellow” philosophy might sound eco-friendly, but it’s actually creating a chemistry experiment in your pipes that would make a science teacher cringe.
Not flushing can lead to bacteria growth, bad odors, and possible contamination. This can increase the risk of spreading infections, especially in shared bathrooms. Urine contains minerals like calcium and magnesium. When left in the bowl, these minerals can harden over time and create stubborn stains that are difficult to remove. Your toilet bowl becomes a petri dish where minerals crystallize and bacteria throw house parties, all while the acidic environment slowly eats away at your pipes like a very patient vandal.
Using Improper Tools for DIY Repairs

Pipes frequently suffer when potent cleaners are poured down sinks or toilets. Plumbers utilize specialized tools, penetrating deeper than store-bought cleaners, to extract unseen waste. Engaging a plumber for cleaning also provides an opportunity to inspect pipes for early trouble signs, averting more significant problems down the line. Weekend warriors armed with YouTube tutorials and hardware store confidence often cause more damage than the original problem they set out to fix.
The temptation to grab whatever tool fits the space might seem logical, but pipes are surprisingly delicate ecosystems that don’t appreciate being treated like construction materials. Using a plunger or a drain snake can be effective for minor clogs. For more stubborn blockages, consider using natural solutions like a mixture of baking soda and vinegar followed by hot water or investing in a drain strainer to prevent debris from entering the pipes in the first place. If the problem persists, it’s advisable to contact a professional plumber who can safely and effectively address the issue without causing further damage to your pipes. The wrong tool can turn a simple blockage into a pipe replacement project faster than you can say “honey, I think I made it worse.”
