Keep reading for simple instructions and smart prevention tips, and a local coupon to save on repairs.

Start Here: Safety, Shutoffs, and Finding the Source

Water moves fast. Act quickly but safely.

1. Shut off water.
2. • Whole-home: Find the main shutoff near where water enters the house. Turn the handle clockwise or quarter-turn the valve perpendicular to the pipe.
   • Fixture-only: Close the small valves under sinks, behind toilets, or above water heaters.
2. Kill power near wet areas. Use the breaker if outlets or appliances are damp.
3. Control the spill. Place a bucket, towels, or a baking sheet to catch water. Move valuables.
4. Decide if it is supply or drain.
5. • Constant leak under pressure, even when fixtures are off, points to supply.
   • Leaks only when you run water point to drain or trap issues.
5. Use your water meter. With fixtures off, if the meter dial spins, you have a pressurized leak.

Local tip: In Lake County homes, freeze-thaw cycles can stress older copper and galvanized lines, especially in unheated garages and lake-facing walls. If pipes feel icy or sit near drafty rim joists, suspect a pinhole or split.

If you smell gas or see sparking, evacuate and call emergency services. For rising water or ceiling sagging, place a small hole in the lowest point of the bulge to release water into a bucket after the power is off. This reduces collapse risk.

Quick Way 1: Stop a Dripping Supply Line or Fixture

These leaks appear at toilet fill lines, faucet hot-cold hoses, or shutoff valves.

Tools and supplies

• Adjustable wrench, pliers
• Teflon thread tape
• Replacement braided stainless supply line or faucet cartridge
• Towels and bucket

Steps

1. Close the nearby shutoff. Open the faucet to relieve pressure.
2. Tighten first. Snug the compression nut or the supply line connection by a quarter-turn. Do not overtighten.
3. Reseat threads. If the drip continues, remove the line, wrap male threads with 3 to 4 clockwise wraps of Teflon tape, and reconnect.
4. Replace worn parts.
5. • Supply line: If the hose is bulged, cracked, or older than 5 to 7 years, replace with a braided stainless line of the same length. Hand-tighten plus a quarter-turn.
   • Faucet cartridge: For a single-handle drip, shut water off, remove the handle, pull the old cartridge, match the part, and install per the diagram in the box.
5. Test. Turn water on slowly while watching the joint. Dry everything and recheck in 15 minutes.

When to call a pro

• Valve stem packing leaks at the shutoff that persist after gentle tightening.
• Green-blue corrosion on copper indicates pitting that will return.
• Hot water lines that keep leaking may point to failed pressure control or expansion.

Pro advantage: Our techs carry common cartridges and braided lines and can install a pressure regulator if high pressure is causing recurring leaks.

Quick Way 2: Patch a Pinhole or Burst Risk on a Pipe

A tiny jet from copper or a hairline crack on CPVC can be stabilized to stop damage until a proper repair.

Tools and supplies

• Epoxy putty rated for potable water
• Rubber patch and a stainless repair clamp
• Emery cloth or sandpaper
• Utility knife
• Towels

Steps

1. Shut off and drain. Close the nearest valve or the main. Open the lowest faucet to drain pressure.
2. Prep the pipe. Dry the area. Lightly sand around the hole to clean. Wipe dust.
3. Epoxy putty. Knead until uniform color. Press firmly over the hole, wrapping 1 inch past all sides. Smooth edges. Let it cure per the label.
4. Add a clamp for security. Place a rubber patch over the area and center a repair clamp. Tighten until snug.
5. Restore water slowly. Watch for weeping. If it holds, you have a safe temporary fix.

Permanent repair options

• Cut out and sweat in a new copper section with couplings.
• For CPVC or PEX, cut square and install new pipe with the correct solvent cement or crimp rings.

When to call a pro

• Multiple pinholes suggest systemic corrosion or high pressure.
• Lines inside finished ceilings, near electrical, or in tight chases.
• Slab or underground lines where water appears from floors or foundation cracks.

Local insight: Near Lake Erie, fluctuating pressure and minerals can speed pinhole formation. A pressure regulator and thermal expansion tank can prevent repeat failures.

Quick Way 3: Fix a Leaking P-Trap or Drain Connection

If the cabinet is soggy only when the sink runs, the trap or tailpiece is likely.

Tools and supplies

• Bucket and towels
• Slip-joint pliers
• Replacement trap kit with washers
• Plumber’s putty or silicone for sink basket leaks

Steps

1. Place a bucket under the trap. Run water to confirm the drip location.
2. Hand-tighten slip-joint nuts. If that stops the leak, dry and recheck.
3. Rebuild the trap if it still drips. Loosen nuts, remove the trap, and replace washers in the correct orientation. Install the new trap pieces without cross-threading.
4. Check the sink strainer. If water sneaks around the basket, remove it, clean surfaces, bed in fresh plumber’s putty, and tighten the locknut evenly.
5. Test with hot and cold, plus a sinkful dumped at once. Look for any weeping along every joint.

Pro tip: If the drain moves when you wiggle it, secure the tailpiece and ensure the tubular pipes are not strained. Stress creates leaks during temperature changes.

When It Is Not DIY: Hidden, Underground, and Hot Water Tank Leaks

Some leaks demand specialized tools and permits.

• Hidden leaks in walls and ceilings. Signs include warm spots underfoot, hissing behind drywall, or constant meter movement. Our team uses advanced leak detection technology to locate leaks accurately without guesswork.
• Sewer or drain line leaks. Slow drains, odors, or yard sinkholes point to cracked pipes. We use video camera inspections to pinpoint problems and design the least invasive repair.
• Underground water, sewer, or gas lines. If the problem is underground, we locate and repair water, sewer, and gas utility lines using underground locating technology and proper safety procedures.
• Water heater leaks. Rusty pan water, dripping from the TPR valve, or tank sweat can all look similar. We diagnose whether you need a new TPR valve, expansion tank, or a full replacement if the tank itself is compromised.
• Emergencies. With 24/7 emergency service we are ready day or night. Ceiling collapse risk, active flooding, or sewer leaks call for immediate help.

Hard facts you can count on

• OH License #12211. Work is done to Ohio code and local ordinances.
• For eligible new sewer line installs from home to utility hookup, we honor a lifetime guarantee of that work.

Prevent the Next Leak in Northeast Ohio Homes

Stopping today’s leak is half the job. Preventing the next one protects your home and wallet.

Control pressure and expansion

1. Install or calibrate a pressure regulator. Target house pressure is typically 55 to 65 psi.
2. Add a thermal expansion tank when required with closed systems or new water heaters. This protects fixtures, valves, and supply lines.

Protect with smart shutoff

• LeakSmart smart home water valves can shut off your main water supply in seconds if a sensor detects water. Sensors, a smart valve, a hub, and a mobile app work together so you can control your home from anywhere. Our plumbers install and set it up.

Seasonal steps for Lake County

• Before hard freezes, insulate garage and crawlspace lines, and disconnect hoses.
• Open vanity doors on exterior walls during deep cold snaps to let heat reach pipes.

Maintenance matters

• Join the H+ Membership to save 15% on service and keep plumbing tuned. Members also receive a 12-month clog-free guarantee on drain cleaning, which helps prevent backups that can become leaks.
• Schedule annual plumbing safety inspections to spot corrosion, worn supply lines, or weak valves before failure.

Know when to replace, not repair

• Supply hoses older than 7 years, shutoff valves that will not seal, and water heaters with tank leaks should be replaced. Strategic upgrades cost less than water damage remediation.

Frequently Asked Questions

How do I find my main water shutoff quickly?

Look where the water line enters your home, often the basement wall facing the street or near the water heater. The valve is a round handle or a quarter-turn lever. Turn clockwise or perpendicular to the pipe to stop flow.

Is epoxy putty a permanent fix for a pipe leak?

No. Epoxy putty is a solid temporary patch. It buys time and stops damage. A permanent repair replaces the damaged section with new pipe or fittings that meet code.

Why does my water heater leak from the relief valve?

High pressure or thermal expansion can cause the temperature and pressure relief valve to open. You may need a pressure regulator or an expansion tank. A failed valve can also drip and should be replaced.

What causes pinhole leaks in copper pipes?

Minerals, velocity, and pressure fluctuations erode copper from inside. Older pipes in uninsulated areas are at higher risk. Managing pressure and adding an expansion tank reduces stress and future pinholes.

When should I call a professional instead of DIY?

Call a pro for hidden or slab leaks, underground lines, sewer leaks, persistent valve leaks, or any leak near electrical. Also call if you cannot reach a safe shutoff or your ceiling is bulging.
