Reasons to Drain Your Plumbing Pipes

a. Water Hammer:

One common reason to drain your plumbing pipes is to address a water hammer issue. Water hammer, also known as hydraulic shock, occurs when plumbing pipes make loud banging noises due to abrupt water flow changes. This can happen when faucets are turned on or off, or when water-flowing equipment starts or stops suddenly. Draining and refilling the system helps reduce air in the plumbing lines, which can alleviate the water hammer problem and prevent damage to the pipes.

b. Seasonal Shutdown:

If you have a seasonal property or live in a cold region where properties are unoccupied during winter, draining your plumbing pipes becomes essential. Failing to do so can lead to frozen pipes that may burst and cause significant water damage. By emptying the plumbing pipes, you minimize the risk of frozen pipes and potential water disasters during the winter months.

c. Major Plumbing Repairs:

During major plumbing repairs or installations, draining the plumbing system may be necessary. For instance, when adding a new bathroom or making extensive modifications to the existing plumbing network, draining the pipes is typically required. This ensures that there is no water flowing through the system, making it safer to cut and connect the pipes without water leakage. Draining can also prevent accidental water damage during the plumbing work.

Understanding these reasons and when they apply to your situation will help you determine when it’s necessary to drain your home’s plumbing pipes. Consulting with a professional plumber can provide guidance and assistance in handling these specific plumbing concerns.

a. Water Hammer:

To address a water hammer issue, the first step is to shut off the water valve at the main water meter. This ensures that no water is flowing into the plumbing system.

b. Seasonal Shutdown:

When preparing for a seasonal shutdown, begin by opening all the sink faucets in your home, starting from the highest level. This helps introduce air into the system, aiding in the drainage process.

c. Major Plumbing Repairs:

During major plumbing repairs, it is necessary to open the faucet in the laundry tub or the lowest sink in your home, typically located in the basement. This allows the water from the upper levels to drain down.

Additionally, open the tub or shower faucets to release any remaining water from the plumbing system. It is essential to flush all toilets in your home to empty the tanks and remove any water still present.

To ensure a thorough drainage process, leave all the faucets in an open position. This allows any remaining water in the pipes to flow out. While this is especially important during a seasonal shutdown, it may also be relevant during water hammer resolution or major plumbing repairs.

Following these steps will effectively drain the water from your plumbing system, preventing any potential issues during repairs, seasonal shutdowns, or water hammer solutions.

Additional Tips for Draining Your Plumbing Pipes

a. Preventing Sewer Gas Escape:

When a home is left unattended for an extended period, standing water in toilets, sink traps, tub drain traps, and floor drains can evaporate, removing the drain seal that prevents sewer gases from rising into the home. To prevent this, some experts suggest plugging drains and toilet basins with wadded-up rags or using plastic wrap. This extra step helps maintain the integrity of the drain seals and keeps sewer gases from entering your home.

b. Protecting the Pipes When Winterizing:

If you are winterizing your plumbing system, it is crucial to absorb all the water from toilets, toilet tanks, traps, and any areas with standing water. This step is necessary because water expands when frozen, which can cause cracks in porcelain fixtures, traps, and appliance fittings. If the home will be kept cool, this step may not be necessary. However, in cases where the heat will be turned off entirely, consider insulating the incoming water supply with heat trace and insulation to prevent freezing.

By following these additional tips, you can ensure a more comprehensive draining process of your plumbing pipes. Taking steps to prevent sewer gas escape and protect the pipes when winterizing will contribute to the proper functioning and longevity of your plumbing system.

How to Recharge the Pipes with Water

6 Steps To Install The Sewer Drain Pipe

a. Water Hammer:

To recharge the plumbing pipes after addressing a water hammer issue, begin by closing the basement or lowest level faucet in your home.

b. Seasonal Shutdown:

During a seasonal shutdown, close all the faucets except for the lowest level one, such as the laundry faucet. This ensures adequate air remains in the pipes to recharge the air chambers in your home’s plumbing system.

c. Major Plumbing Repairs:

After completing major plumbing repairs, you can restore water flow and refill the pipes by following these steps:

1. Closing the Basement Faucet:

Shut the faucet in your basement or the lowest level of your home.

2. Closing the Upper Faucets:

Close all the faucets in your home, starting from the top floor and working your way down. This helps retain air in the pipes to recharge any air chambers in your plumbing system.

3. Opening the Main Water Valve:

Open the main water valve to allow water to flow back into your pipes.

4. Turning on the Faucets:

One by one, starting from the highest level faucets, turn on the faucets and let the water/air sputter out until you witness clear water flowing consistently. Initially, you may notice brownish water, but this should clear up.

5. Opening Other Faucets:

Open the shower faucets to allow water to return to the pipes.

6. Flushing the Toilets:

Flush the toilets to refill the tanks.

7. Turning off the Faucets:

Finally, turn off the faucets after the water is clear, starting from the top floor and working your way down. You may experience the occasional sputter the next time you use a faucet, but the pipes will quickly purge any remaining air.

By following these steps, you can successfully recharge the water supply in your plumbing system and resume normal water flow throughout your home.
