Common Sources of Plumbing Leaks

In our years of experience providing commercial and residential leak detection services, we’ve identified several typical sources of plumbing leaks. Being aware of these can assist homeowners and business owners alike in early leak detection and timely intervention:


Toilets – The internal workings of toilets can often be a culprit. From worn-out flappers to malfunctioning fill valves, these issues can cause water to seep continuously into the bowl or tank.


Faucets and Showerheads – A constant drip might seem like a minor nuisance, but over time, it results in significant water loss. Faulty washers, corroded valve seats, or worn-out seals are common causes.


Pipes and Pipe Joints – Aged structures or those with copper pipes are especially susceptible. Corrosion, high water pressure, or drastic temperature changes can lead to weakened or burst pipes. Signs to watch out for include discoloration, dimpling, or any visible damage on exposed pipes.


Water Heater – Over time, your water heater might develop leaks, especially at the base. Rust, sediment buildup, or a malfunctioning pressure relief valve are frequent causes.


Appliances – Appliances like washing machines and dishwashers are common leak culprits. Regularly check hoses, especially at connection points, for signs of wear, bulging, or corrosion.


Under-Sink Plumbing – The cabinets under sinks hide plumbing that can sometimes leak, especially if seals degrade or pipes become loose.


Exterior Faucets and Hose Bibs – Wear and tear, corrosion, or freezing temperatures can cause these to leak. It’s especially important to check these before winter sets in.


Sewer and Drain Lines – Over time, these lines can get clogged, cracked, or punctured. Tree roots, shifting soil, or deteriorating materials can all cause these underground leaks.


Garbage Disposals – Improper installation, wear and tear, or even certain foods can cause garbage disposals to leak.


Regular inspections, especially of these common sources, are crucial. If you notice any signs of water damage or suspect a leak, don’t hesitate to call in commercial and home leak contractors for a thorough assessment and repair in the San Fernando Valley or Ventura County.


Slab Leaks

Slab leaks are one of the more serious and challenging leaks to detect and repair due to their location beneath the concrete foundation of a building. They occur in the water lines situated directly below your building’s slab foundation. Causes can range from ground shifts and corrosion to poor construction or high water pressure.


A slab leak requires professional leak detection and repair. Some signs of a potential slab leak include:


Unexpected Spikes in Water Bill – If your bill suddenly increases without a change in usage, a slab leak might be the culprit.


Sound of Running Water – If you hear the sound of water running even when all fixtures are off, it’s a warning sign.


Hot Spots on the Floor – A leak in a hot water line can create warm spots on your floor.


Cracks in Walls or Floors – Excessive moisture from a slab leak can cause your building to shift slightly, leading to visible cracks.


Mold or Mildew Under Carpets – Moisture can seep upwards, leading to mold or mildew formation beneath floor coverings.


Detecting and addressing slab leaks early is crucial to prevent structural damage to your home or business and avoid exorbitant repair costs. Always call in a commercial or home leak contractor with experience in handling slab leaks if you suspect one.

How Do I Know I Have a Leak?

Detecting a leak early is essential to prevent potential damage to your home or business. But how can you be sure there’s a hidden leak? Here are some of the most telling signs:

Higher Than Average Monthly Bill

Explanation: An unexpected spike in your water bill, despite consistent water usage habits, is a clear indicator of potential leaks. Small leaks can accumulate, leading to a significant increase in monthly costs.


What to Do: Review your past few months’ bills. If you notice a consistent upward trend without any known increase in water usage, consider it a warning sign.

Low Water Pressure

Explanation: A sudden drop in water pressure can result from a leak in your plumbing system. This means that water isn’t reaching its destination as efficiently as it should.


What to Do: Check multiple water outlets in your home or business. If more than one has diminished pressure, the cause might be a leak in a main water line.

Mold and Mildew

Explanation: Persistent dampness from hidden leaks provides the perfect environment for mold and mildew to thrive. They can appear on walls, ceilings, or floors, and might even give off a musty odor.

What to Do: Regularly inspect commonly damp areas like basements, bathrooms, and kitchens. If you spot mold or smell a persistent musty odor, it might be due to a hidden leak.

Water Stains

Explanation: Hearing sounds like dripping, rushing water, or a constant hiss when no water outlets are on can indicate a leak.


What to Do: Be attentive to any unusual sounds, especially during quiet times. Try turning off all faucets and appliances, then listen carefully for any signs of water movement.


If you notice any of these signs or have suspicions of a hidden leak, don’t hesitate to get professional leak detection services. Early intervention can prevent more significant issues down the line.

Leak Detection System

Rather than living in fear of undetected leaks, consider installing a proactive leak detection system. Here’s how this technology can benefit you:


Connectivity – Typically attaches to your main water line to keep a vigilant check.


Temperature Monitoring – Detects unusually low temperatures that might indicate freezing pipes, which are dangerous as water expands when frozen. This expansion can burst a pipe, causing floods, especially during colder nights.


Instant Alerts – If the system detects an anomaly, it sends an immediate notification to your phone.


Automatic Shutdown – In case of a potential leak, the system can shut off your water supply, preventing further damage.


Usage Monitoring – Through an app on your phone, monitor your water consumption and even get suggestions on upgrades to conserve water.


Remember, leaks don’t just mean water wastage—they can compromise the very integrity of your home or business.


Stay ahead with an efficient leak detection system and always have experts like us on speed dial for commercial or home leak and drain solutions.

DIY Leak Detection

Adding a leak detection system to your home or business is a long-term solution that stops leaks. However, if you think you already have a leak, there are a few ways you can confirm your suspicions.

Here are a few methods to detect leaks:

Toilet Test – The bathroom is usually where you use the most water. So, a quick way to find leaks is to test your toilet. Add food coloring to the toilet tank, and don’t use it for ten minutes. If the dye appears in the bowl while the toilet isn’t being used, there’s a leak.

Meter Check – Receiving an unexpectedly high water bill is usually not the surprise gift most homeowners or business owners want. Monitor the water meter by writing down its number before you turn all the water fixtures off for a few hours. When you come back, you have a leak if the number has risen.

Visual Checks – Check for visible leaks in the back of cabinets, under sinks, and around the toilet. Anywhere you smell mildew or see mold without dripping has excessive moisture that a leak behind a wall could cause.

We want to help protect your home or business from water damage with our expert residential and commercial leak detection services in Ventura County and Los Angeles County. Don’t waste money or water with an undetected leak that causes preventable problems with your property’s support.
