At John G. Plumbing Inc., we know that quick action is key. We’ve structured this guide to help you manage the emergency, identify common issues, and know exactly when it’s time to call our professional plumbers. When in doubt, give us a call at (250) 797-0858.

  • What to do when a pipe unexpectedly bursts in your home.

  • How to identify your faucet type.
  • Toilet won’t stop running? Common causes and quick fixes.

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.

Water shut-offs are usually either a ball valve or a gate valve style

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)

  1. Turn Off the Water:
    Use the main valve immediately.
  2. 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.
  3. 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.

Don’t want to take any chances? Call John G.

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 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!
