Pipe burst? Shut off the water first.

When you hear the terrifying sound of rushing water, panic is natural, but immediate action is critical. Stopping the flow of water is the single most important thing you can do to save your home.

What is the first step when a pipe is leaking?

Your absolute first priority is to turn off the water supply.

How to find your main water shut-off valve

Interior Location: In most homes, the main shut-off valve is located near the perimeter of the house where the main water line enters. Check your utility room, basement, or crawl space, often near the water heater. Do you have a hose outside? Look in the basement near where it is set up, the shut-off valve might be close by.
Exterior Location: If you can’t find a valve inside, look for the curb stop (the municipal shut-off) in a concrete or plastic box near your property line. You may need a specific tool (or a service call from a plumber) to turn this off.

What to do if a pipe bursts (Emergency steps)

Turn Off the Water:
Use the main valve immediately.
Turn Off the Power:
If the leak is near electrical wiring, switches, or appliances, turn off the electricity to that area at your main breaker panel. Safety is paramount.
Minimize Damage:
Open the nearest faucet to drain remaining water from the affected line. Start documenting the damage with photos or videos.

What is the danger of waiting to repair a leaking pipe? Even a small, slow leak can lead to wood rot, compromised structural integrity, black mold growth, and astronomical, unnecessary water bills. Do not delay professional contact.

How to Fix a Leaky Faucet (Step-by-Step Guide)

A persistent drip can be more than just annoying; it can waste hundreds of gallons of water per year. The repair often comes down to the type of faucet you have.

How to identify my faucet type

Wondering what kind of faucet you have? Faucets are categorized by their inner mechanism, which dictates the repair part you need. So, how it is built will determine how it will get fixed.

faucet types — Faucet types starting from the upper left, going clockwise: compression, cartridge, ceramic disc, and ball.

Faucet Type Identification Guide

Faucet Type	How to Identify It Easily	The Problem Part (What Needs Fixing)
Compression (Older Style)	Two Separate Handles (one for hot, one for cold). You must tighten the handle to stop the water, like turning off a garden hose.	Washers (Small rubber rings inside the handles wear out).
Cartridge (Common Modern)	Single Handle that moves up/down* for water volume and left/right for temperature. Water stops when you move the handle to the OFF position.	Cartridge (A cylinder with movable ports that controls water flow).
Ball (Distinct Design)	Single Handle with a round, ball-shaped cap over the joint. It moves and rotates around the spout. (Usually a difficult, older single-handle design).	Ball Joint Assembly (Multiple small seals and springs inside the mechanism).
Ceramic Disc (Newer High-End)	Single wide, flat handle that moves over a wide arc. They are very reliable and typically have a wide, circular base on the spout.	Ceramic Disks (Two polished ceramic plates that control water flow).

Troubleshooting a leaky faucet handle or spout

First, turn off the water supply under the sink. Disassemble the handle and spout to access the core mechanism. For compression faucets, you likely need a new washer. For cartridge or disk faucets, you will need a matching replacement cartridge.

When is it better to replace the whole faucet instead of repairing it?

If your faucet is old, showing heavy corrosion, or if replacement parts are unavailable or difficult to source, a full replacement is more cost-effective. Sometimes, you just want to update the look!

How to Silence a Running Toilet and Stop Hidden Leaks

A running toilet is the most common and expensive hidden leak in a home. The sound of water constantly refilling the tank is a signal that money is literally going down the drain. And hey, if you have kids, they’ve likely flushed a toy once or twice. So, let’s help you solve this mystery of the day.

How to check and adjust the flapper or fill valve

The two main culprits in a running toilet are the flapper (the rubber plug) and the fill valve (the mechanism that refills the tank).

1. Check the Flapper (The Rubber Plug)

The flapper’s job is to create a perfect seal to hold water in the tank until you flush. Take the lid off the back of the toilet. The water inside the tank may look perfectly clean, but it can sometimes look discolored or have build-up depending on your home’s water quality. It’s ok to touch!

Once inside, you’ll see a structure connected to a chain, which then connects to a little seal on the bottom.

Look for Slack: Check the small chain connecting the flush handle to the flapper. It needs a little bit of slack. If the chain is too short and tight, it keeps the flapper slightly pulled up, meaning water constantly leaks into the bowl.
Inspect the Seal: Gently lift the tank lid and check the rubber flapper itself. If it looks slimy, warped, or if the rubber is brittle or cracked, it won’t seal properly. This is the most common fix and requires a simple flapper replacement.

2. Check the Fill Valve (The Water Level)

The fill valve (or ballcock) is the main control mechanism inside the toilet tank that manages the water supply. Its primary job is twofold: first, it opens to refill the tank immediately after a flush using water from your home’s supply line. Second, and most critically, it uses an attached float (a cup or arm) to monitor the rising water level and automatically shut off the flow when the water reaches the optimal fill line, which prevents the toilet from continuously running and wasting water.

Fill valve troubleshooting:

Check the Water Height: The water level should be about one inch below the top of the overflow tube (the thin pipe in the center).
Adjust the Float: If the water is too high, it constantly spills down the overflow tube, making the toilet “run.” Locate the float (a cup or arm) and adjust its setting so the fill valve shuts off the water before it reaches that overflow line.

Why does my toilet keep running after replacing the parts?

If you’ve replaced the flapper and fill valve and the toilet still runs, the issue may be more complex. This could indicate a warped or damaged flush valve seat or an issue with the siphon jet. At this point, it’s time for a professional plumber inspection.

How much money can a running toilet cost per month?

A continuously running toilet can waste over 200 gallons of water per day, potentially adding hundreds of dollars to your annual water bill!

The Repiping Process: A Step-by-Step Guide

Written by Ysabel Mano on February 11, 2025. Posted in Bathroom Renovation, burst pipes, Renovations, Repiping.

If your home was built between the 1970s and 1990s, there’s a chance it has Poly-B (polybutylene) piping. Many home insurance providers in Canada no longer cover homes with Poly-B pipes, and some companies may even require proof of pipe replacement before offering a policy.

At John G Plumbing, we specialize in Poly-B pipe replacement to help homeowners protect their property, secure home insurance, and prevent costly water damage. Here’s what you can expect from our five-step repiping process:

Step 1: Mapping Out the Most Cost-Effective Method

Before starting, we assess your home’s plumbing system and discuss the best repiping options. Cost to replace Poly-B piping in BC varies based on home size, pipe material (PEX or copper), and labor. We prioritize a cost-effective approach while ensuring your new plumbing system meets Canadian insurance requirements.

Step 2: Preparing by Cutting Drywall Pieces

We carefully cut drywall in necessary areas to access the old Poly-B pipes, minimizing damage for easy repairs. This step ensures an efficient repiping process without unnecessary demolition.

What insurance companies cover Poly-B pipe replacement?
Some insurance providers in Canada will cover part of the repiping cost. Contact your home insurance provider to discuss potential coverage options.

Step 3: Dry-Fitting the New Pipe System

Before making any permanent changes, we dry-fit the new PEX or copper pipes to ensure proper alignment and efficiency. This step is crucial to avoiding future plumbing problems.

Step 4: Turning Off Water & Connecting to Fixtures

Once we’re ready, we turn off the water, remove the old Poly-B pipes, and install the new plumbing system. Our team ensures all connections are secure before testing for leaks. Replacing Poly-B pipes is the best way to lower your home insurance costs and protect your property from expensive water damage

Can you get homeowners insurance with Poly-B piping?
Many insurance companies in Canada will either:

Deny coverage outright.
Charge higher premiums for homes with Poly-B pipes.
Require a full Poly-B replacement before renewing or issuing a policy.

Step 5: Walkthrough to Ensure Customer Satisfaction

Before completing the project, we do a final walkthrough with you to ensure everything meets your expectations. We also provide documentation of the repiping work, which may help you negotiate better home insurance rates.

Why Repiping Matters

Repiping your home prevents costly leaks, improves water quality, and increases plumbing efficiency. If you’re dealing with low water pressure, discolored water, or frequent pipe leaks, it might be time to consider repiping.

When Pipes Burst: What you need to know

Written by Ysabel Mano on November 21, 2024. Posted in burst pipes.

Winter is coming, and every homeowner knows the drips of disaster when pipes burst. Avoid the stress of damage and expenses by knowing what to do if pipes burst, how to prevent pipes from bursting, and how to fix them.

Your Water Pipes Burst? Here are your steps to take

Imagine: You hear a loud noise from the basement then come downstairs to see water pouring out of your pipes and flooding everywhere. It looks like a burst pipe, but what do you do?

Step 1: Stay calm.
Step 2: Turn off the main water and power supply. It is dangerous to have electricity and water interact with each other.
Step 3: Locate the damage and try to contain the leak using buckets to collect any additional dripping water.
Step 4: Call John G Plumbing for advice on the next steps and for a professional eye to determine if other pipes are at risk of breaking.
Step 5: Prevent mold and mildew growth. Clean up, open the windows or turn on fans to improve airflow.

Don’t forget the hassle of dealing with insurance claims. Take pictures and document the damage. Dealing with pipes bursting is enough to give you nightmares. However, professionals at John G are here to help get your home back in working order.

Frozen Pipes! How to prevent burst pipes

Have you ever wondered why pipes burst in winter more often than in the summer? Frozen Pipes! Below-freezing temperatures freeze water in the pipes, making it expand. Other reasons include old age, high water pressure, clogs, earthquakes, improper installations and corrosion.

Hence, prevention is key! John G. Plumbing has some quick tips to help you prevent a disaster from happening.

Insulate pipes in unheated or exposed areas, such as crawl spaces, attics, and exterior walls. Use pipe insulation sleeves or wrapping material designed for this purpose.
Set your thermostat to a temperature that will prevent frozen pipes even when outside temperatures drop below freezing.
Inspect your home for any gaps or cracks that could allow cold air to enter near pipes. Seal these openings with caulk or insulation to prevent cold air from reaching the pipes and causing them to freeze.
Before winter arrives, disconnect garden hoses from outdoor faucets. Drain the water from the hoses and store them in a sheltered location. Shut off the water supply to outdoor faucets, if possible, and drain any remaining water from the pipes to prevent freezing.
During extremely cold weather, allow faucets connected to vulnerable pipes (such as those running along exterior walls) to drip slightly. This helps relieve pressure within the pipes, reducing the likelihood of freezing.

A cracked pipe isn’t always obvious

Smaller pipes in the home can burst and take a little longer to identify as they don’t carry the high water pressure of a main water line. These leaks can often go unnoticed for weeks, or even months, depending on where they are located.

Here are some signs that smaller pipes may have already burst in your home:

Random puddles of water in your home.
A higher-than-usual water bill, despite no increase in usage.
Yellowish stains or spots on walls and ceilings.
Noticeably reduced water pressure.

Repairing Pipes- is fixing an option?

Fixing burst pipes is best left to a professional plumber, but you can make emergency repairs if applicable. Repair sleeves can temporarily reinforce the pipe to be able to run water through it. You can also patch it with a piece of rubber, place a wood block over it or use a clamp and clamp it all together. These are all temporary fixes if you are unable to have a plumber arrive immediately to check things out.

Temporary solutions can initiate further damage if not treated properly. It is best to call our licensed plumbers at John G. Plumbing for a reliable inspection, repair, and replacement if necessary.

Don’t Let a Burst Pipe Ruin Your Day!

Think you might have a hidden leak in your home? Don’t wait until it becomes costly! Keep an eye out for these signs, and if a disaster happens, contact John G. Plumbing for repair.
