10 Common Plumbing Problems & How To Spot Them

Plumbing issues can be a frustrating and costly inconvenience for homeowners and businesses alike. While some problems may seem minor at first, they can quickly escalate into significant repairs if left unaddressed. Recognising the early signs of plumbing problems can help prevent water damage, save money on repairs, and ensure your plumbing system remains in good working condition.

In this guide, we’ll cover 10 common plumbing problems, how to spot them, and why timely action is essential.

A dripping tap might seem like a minor issue, but even a slow leak can waste litres of water daily and lead to higher utility bills. This problem is often caused by worn-out washers, O-rings, or valve seats. If you notice constant dripping, it’s best to have a professional plumber inspect and replace the faulty components before the issue worsens.

Leaky pipes are a common issue, particularly in older homes or buildings with outdated plumbing systems. Signs of a leak include:

• Damp spots on walls, ceilings, or floors
• Mildew or mould growth
• Unexplained increases in water bills

Leaks can occur due to pipe corrosion, loose joints, or excessive water pressure. Left untreated, they can cause structural damage and encourage mould growth, which poses health risks. Professional repairs ensure the leak is correctly sealed and prevent further damage.

A running toilet can waste hundreds of litres of water per day, significantly increasing water bills. This issue is often caused by:

• A faulty flapper valve that fails to seal properly
• Issues with the float mechanism
• Sediment buildup affecting flushing efficiency

If adjusting the float or flapper doesn’t solve the problem, a plumber can replace the necessary components to restore normal function.

Low water pressure can make daily tasks like showering or washing dishes frustrating. Possible causes include:

• Pipe corrosion reducing water flow
• Hidden leaks causing pressure loss
• Sediment buildup in taps or showerheads

If cleaning the aerators or showerheads doesn’t improve the pressure, a plumber can diagnose and fix the root cause to restore normal water flow.

Slow-draining sinks or showers are often caused by hair, grease, soap scum, or foreign objects blocking the pipes. Warning signs include:

• Standing water in sinks or tubs
• Gurgling noises from drains
• Foul odours

While store-bought drain cleaners provide a temporary fix, they can damage pipes over time. A professional drain cleaning service ensures the blockage is removed safely without harming your plumbing system.

If your water heater isn’t providing consistent hot water, it could be due to:

• Sediment buildup in the tank reducing efficiency
• A faulty thermostat
• Corrosion or leaks in the unit

Signs of trouble include fluctuating water temperatures, discoloured water, or unusual noises from the heater. Regular maintenance, such as flushing the tank and checking heating elements, helps extend its lifespan. If issues persist, a plumber can repair or recommend a replacement unit.

A sewer backup is one of the most severe plumbing problems, often requiring immediate professional attention. Signs of a sewer backup include:

• Multiple drains clogging at once
• Gurgling noises from toilets or sinks
• Foul odours from drains

Common causes include tree root infiltration, blockages, or damaged sewer lines. Sewer backups pose health risks, so it’s crucial to contact a licensed plumber as soon as you notice these warning signs.

Garbage disposals can jam or malfunction due to:

• Disposing of fibrous or hard materials (e.g., bones, coffee grounds, or grease)
• Overuse without proper flushing
• Loose connections or motor failure

If resetting the unit doesn’t work, a professional plumber can inspect the disposal, remove jams, or recommend a replacement if necessary. Regular maintenance, such as running cold water while using the disposal, can help prevent issues.

Leaky hose bibbs are common, especially after winter, due to exposure to the elements. Signs include:

• Water drips near the outdoor tap
• Water stains on exterior walls
• Difficulty turning the tap off completely

A leaky hose bibb can waste significant amounts of water and may lead to water damage. Replacing it with a frost-proof model can help prevent future leaks.

Hard water, which contains high levels of minerals like calcium and magnesium, can cause limescale buildup in pipes, taps, and appliances. Signs of hard water include:

• White spots on dishes or glassware
• Reduced soap lathering
• Frequent clogging of showerheads

Over time, hard water can reduce the efficiency of your plumbing system and appliances. Installing a water softener can help mitigate these issues, prolonging the life of your pipes and fixtures.

Plumbing issues can escalate quickly if left unaddressed, leading to costly repairs, structural damage, and health risks. Acting fast helps:

• Prevent Structural Damage – Leaks can weaken walls, floors, and foundations, leading to mould growth and electrical hazards.
• Save on Repairs – Small issues like slow drains or minor leaks can turn into major emergencies if ignored, requiring expensive fixes.
• Improve Water Efficiency – Running toilets and leaking taps waste thousands of litres of water, increasing utility bills.
• Protect Health & Safety – Excess moisture encourages mould growth, while faulty pipes can contaminate your water supply.
• Extend Appliance Lifespan – Plumbing issues can strain water heaters, dishwashers, and washing machines, leading to early breakdowns.

If you notice persistent leaks, water stains, slow drainage, or unusual noises, don’t wait—professional repairs can prevent bigger problems down the line.
