12 Common Plumbing Problems and How to Avoid Them

1. Slow-draining sink

A slow-draining sink can be attributed to a variety of factors, typically stemming from obstructions within the plumbing system.

Accumulation of debris can form clogs that restrict the smooth flow of water through the drain pipes. For example,

  • hair

  • soap residue

  • food particles is a common culprit,

These obstructions can accumulate over time and impede drainage, leading to the slow-draining phenomenon.

In addition to debris buildup, mineral deposits can contribute to slow drainage, especially in regions with hard water like Kitcheneer-Waterloo.

The minerals in hard water gradually accumulate inside the pipes, narrowing the diameter and reducing the efficiency of water flow.

Furthermore, faults within the plumbing configuration, like a damaged or misaligned pipe, can create areas where debris collects and compounds the issue, causing water to drain slowly.

 

DOn’t let a slow draining sink turn into a flood of other common plumbing problems.

2. Clogged bath or shower drain

Similar to a slow-draining sink, a clogged bath or shower drain often occurs due to the accumulation of hair, soap scum, and other debris within the drain pipe over time.

As you shower or bathe, hair and soap particles can wash down the drain and become entangled, creating a blockage. This gradually restricts the flow of water and leads to a clogged drain.

Additionally, the combination of hair and soap scum can act as a sticky trap for other particles, exacerbating the clog and making it harder for water to pass through.

Hard water can also contribute to clogged tub drains over time. Hard water contains high levels of minerals such as calcium and magnesium. As water flows through pipes, these minerals can gradually deposit and build up on the interior surfaces of the pipes. This buildup can lead to reduced water flow and eventually contribute to clogs in the tub drain.

Solution

Regular maintenance, such as using drain covers to catch hair and soap scum, and periodic cleaning using methods like baking soda and vinegar or a plumbing snake, can help prevent and address clogged bath or shower drains.

3. Clogged toilet

Common plumbing problems usually revolve around toilets.

A clogged toilet occurs when something gets lodged in the drain pipe or trap, preventing water and waste from flushing properly.

Common culprits include:

  • excessive toilet paper

  • sanitary products

  • paper towels

  • foreign objects accidentally flushed down the toilet.

As these items accumulate in the pipes, they create a blockage that hinders water flow, leading to a clogged toilet.

Moreover, the design of a toilet's plumbing system includes a trap and a bend in the drain pipe to prevent sewer gases from entering the bathroom. However, this configuration can also make the toilet susceptible to clogs.

If the trap or bend becomes obstructed by a large object or a buildup of debris, water and waste can't move freely, resulting in a clog.

Preventing clogged toilets involves being mindful of what you flush and using an appropriate amount of toilet paper.

Avoid flushing anything other than toilet paper and bodily waste.

Solution

If a clog does occur, using a plunger or a toilet auger can often clear minor obstructions. For more stubborn clogs, professional plumbing assistance may be necessary to prevent damage to the toilet and pipes.

 

Is your toilet running? Better catch it.

4. Running toilet

A running toilet typically occurs when there is a malfunction in the toilet's flushing mechanism.

One common cause is a faulty flapper valve. The flapper is the rubber component in the toilet tank that lifts when you flush, allowing water to flow from the tank into the bowl. If the flapper doesn't seal properly after the flush, water will continue to leak from the tank into the bowl, causing the toilet to run. This can waste a significant amount of water over time.

Another reason for a running toilet is an issue with the fill valve or float mechanism. The fill valve controls the water level in the tank and refills it after a flush. If the fill valve is not functioning correctly, it might allow water to continuously flow into the tank, causing it to overflow into the overflow tube and leading to a running toilet.

Similarly, if the float, which is usually a ball or cup, is set too high, it might not signal the fill valve to shut off when the water level is appropriate, causing continuous water flow.

Solution

To address a running toilet, start by checking the flapper for proper sealing and adjusting the float mechanism if necessary.

If these adjustments don't solve the issue, it might be a good idea to consult a plumber or replace any faulty components to prevent water waste and higher water bills.

5. Faulty water heater

Spotting a faulty water heater requires observing various signs that indicate a potential problem.

One key indicator is a significant decrease in hot water supply. If you notice that your hot water runs out quickly or doesn't reach the usual temperature, it could signify a malfunctioning water heater.

Additionally, if you find that the water is constantly fluctuating between hot and cold while using hot water, this inconsistency might point to an issue with the heater's thermostat or heating element.

Another sign to watch for is water leakage around the water heater. Puddles, dampness, or rust around the base of the heater could indicate a leak from a corroded tank or a damaged pressure relief valve.

Strange noises, such as popping, banging, or rumbling sounds coming from the heater, are also potential indicators of sediment buildup inside the tank, which can reduce the heater's efficiency and lifespan.

Solution

If you notice any of these signs, it's recommended to have a professional plumber inspect and assess your water heater to determine the extent of the issue and perform necessary repairs or replacements.

 

Decrease in hot water supply is one of the more common plumbing problems.

6. Low water pressure

Low water pressure can stem from several factors, including:

  • Mineral buildup or sediment accumulation in pipes

  • Apartially closed water valve

  • A faulty pressure regulator

  • Leaks in the plumbing system

  • A watermain issue in your area

These common plumbing problems restrict the flow of water, leading to reduced water pressure at faucets and fixtures throughout your home.

Identifying the specific cause is crucial for addressing the problem effectively and restoring proper water pressure.

 

Low water pressure is one of many common plumbing problems.

7. Jammed garbage disposal

Identifying a jammed garbage disposal involves observing specific indications that suggest a blockage or obstruction within the unit.

One prominent sign is the absence of the usual grinding noise when you turn on the disposal. Instead, you might hear a distinct humming sound as the motor runs without the expected sound of food being processed.

This indicates that the impellers, which are responsible for chopping up waste, are likely stuck due to a jam.

Another indicator is a slow drainage of water from the sink when the disposal is in operation. If water accumulates or drains sluggishly, it could suggest that the waste is not being properly processed and is causing a blockage.

 

if you suspect a jammed garbage disposal, you should never attempt to use your hands to remove the obstruction.

8. Leaky pipes

Detecting leaky pipes involves being attentive to visible signs and changes in your plumbing system.

Common indicators include:

  • the presence of water stains

  • discolouration

  • mould growth on walls, ceilings, or floors near pipes.

These patches might appear discoloured, damp, or even have a musty odour. Another clue is a sudden increase in your water bill, which could suggest water loss due to an undetected leak.

Unexplained dripping sounds or the sensation of water running even when no faucets are open could also signify a leak.

Pay attention to water pressure changes, as a drop in pressure might result from water escaping through a leak.

Solution

Regularly inspecting exposed pipes for visible cracks, corrosion, or wetness can also help you spot potential leaks early.

Get it looked at before common plumbing problems become a plumbing emergency.

 

If you suspect a leak, it's advisable to have a professional plumber conduct a thorough inspection.

9. Sewer system backup

A sewer system backup can manifest through several noticeable signs.

One prominent indicator is multiple drains throughout your home becoming slow or completely clogged simultaneously.

If you notice that water is draining slowly from sinks, showers, tubs, and toilets all at once, it could suggest a blockage or backup in the main sewer line.

Additionally, gurgling sounds coming from drains or toilets when you use other plumbing fixtures can be a sign of air trying to escape from a blocked sewer line.

The presence of foul odours emanating from drains, toilets, or even your yard can also be a red flag for a sewer system backup.

If the wastewater cannot flow properly due to a blockage, it might lead to sewage backup, causing an unpleasant smell. If you observe any of these signs, it's crucial to address the issue promptly by calling a professional plumber.

A sewer system backup can be unsanitary and damaging to your property, so it's essential to have it resolved by an expert to prevent further common plumbing problems.

 

Trust us, you don’t want to experience a sewer system backup in your bathroom.

10. Dripping faucets

Dripping faucets are usually caused by a worn-out or faulty internal components, commonly the rubber washer or O-ring, within the faucet assembly.

When the faucet is turned off, these components are meant to create a tight seal to prevent water from flowing. Over time, due to usage and exposure to minerals in the water, these parts can deteriorate, resulting in a leaky faucet.

The water that escapes through the leak is typically due to residual pressure in the plumbing system, causing water to seep through the compromised seal and drip from the faucet.

 

Faucet upgrades can prevent common plumbing issues like drips and leaks.

11. Sump pump failure

A sump pump failure occurs when the sump pump, which is designed to prevent flooding by removing excess water from a designated area, malfunctions or stops working effectively.

Several factors can contribute to sump pump failure. Electrical issues, such as power outages or tripped circuit breakers, can cause the pump to shut off or not operate when needed.

Mechanical problems, like a jammed or clogged impeller (the part that moves water), a stuck float switch (which triggers the pump), or a worn-out motor, can also lead to sump pump failure.

Additionally, a lack of regular maintenance can contribute to failure. If the pump's components become clogged with debris, or if the pump itself isn't tested and maintained periodically, it might not perform as intended during heavy rainfall or flooding.

Solution

To avoid sump pump failure, it's important to schedule regular maintenance, test the pump's functionality, and consider having a backup sump pump or battery-powered backup system in case of power outages.

This helps ensure your sump pump is in good working condition and capable of effectively preventing water damage in your basement or crawl space.

12. Water Leaks

We talked about leaky pipes, but common plumbing problems like household water leaks refer to unintended releases of water from plumbing fixtures, pipes, or appliances within a home.

These leaks can occur due to various reasons, such as deteriorated or faulty plumbing components, temperature fluctuations, or external factors.

Common sources of household water leaks include:

  • Faucets

  • Toilets

  • Showers

  • Pipes

Leaks can lead to a range of issues, including water damage to walls, ceilings, and floors, as well as the growth of mould and mildew. They can also result in higher water bills and wasted resources.

Solution

Detecting leaks early is crucial to prevent these potential damages and expenses. Regularly checking for visible signs of water stains, wetness, or mould growth, as well as monitoring water usage and water meter readings, can help identify leaks promptly.

 

Addressing leaks as soon as they're detected through repairs or replacements by a professional plumber can mitigate damage and save both water and money.

13. How to avoid common plumbing issues

To avoid common plumbing issues, here are some preventive measures you can take:

  • Regular Maintenance: Schedule regular plumbing inspections by a professional plumber. They can identify potential issues early and address them before they escalate into major problems.

  • Proper Usage: Educate your household members about proper plumbing usage. Avoid flushing items down the toilet that are not meant to be flushed, such as paper towels, feminine hygiene products, and excessive toilet paper.

  • Be Mindful of Grease: Avoid pouring grease or cooking oil down the kitchen sink. Grease can solidify in pipes, leading to clogs.

  • Use Drain Covers: Install drain covers in sinks, showers, and tubs to catch hair, soap scum, and other debris before they can cause clogs.

  • Regularly Clean Drains: Clean your drains periodically by using natural remedies like a mixture of baking soda and vinegar followed by hot water. This can help prevent buildup in the pipes.

  • Proper Garbage Disposal Use: Be careful about what you put in your garbage disposal. Avoid putting fibrous foods, bones, and large amounts of food scraps down the disposal.

  • Monitor Water Pressure: If you notice a sudden drop in water pressure, it could indicate a problem in your plumbing system. Address this issue promptly to prevent further damage.

  • Maintain Water Heater: Flush your water heater regularly to remove sediment buildup, which can affect its efficiency and lifespan.

  • Winter Preparation: During colder months, prevent frozen pipes by insulating exposed pipes and allowing faucets to drip slightly to prevent freezing.

  • Sump Pump Maintenance: If you have a sump pump, make sure it's functioning properly by testing it regularly. Clean out any debris in the sump pit that could obstruct its operation.

  • Address Leaks Promptly: If you notice any leaks, even minor ones, address them immediately. Ignoring leaks can lead to water damage and mould growth.

  • Properly Store Chemicals: Avoid storing harsh chemicals or corrosive substances near your plumbing system. These chemicals can cause damage if they come into contact with pipes or fixtures.

  • Mindful Landscaping: Be cautious when planting trees or shrubs near your property. Their roots can potentially invade your plumbing system, causing blockages or damage.

  • Install Water Softener: If you live in an area like ours with hard water, consider installing a water softener. Hard water can lead to mineral buildup in pipes and appliances, reducing their efficiency and lifespan.

By following these preventive measures and being proactive in maintaining your plumbing system, you can significantly reduce the likelihood of encountering common plumbing issues.
