While it isn’t a typical chore, draining the house’s water pipes can be essential. There are many reasons to do this: fix an issue with a water hammer, water hammer issue closing down a property that is closed during winter, or perform significant plumbing repairs, like replacing or expanding one of the primary water lines. Although draining a home’s plumbing lines may appear ,daunting, it’s pretty simple. Let’s review the main reasons why you could want to do this.

Water Hammer

A water hammer (also known as hydraulic shock) (also known as hydraulic shock) is a scenario that occurs when pipes in the plumbing bang loudly when faucets are switched on and off or when a device suddenly can stop or start flowing water. The issue is caused by air trapped in the plumbing lines that permit the water to move around and bounce the pipes against each other and wood frames. Even if the system is equipped with air chambers that absorb this shock, the amount of air accumulating in the system will cause the issue to continue to linger. The solution is to drain the system, then replenish it with air so that the air gaps are restricted to designated air chambers.

Seasonal Shutdown

The plumbing pipes need to be drained. This is one of the many things on a winter-related list. This is especially crucial when a home in colder climates will remain unattended throughout winter. The pipes that freeze and burst could cause a house to flood by dumping thousands of gallons of water and cause hundreds of thousands of damage.

Major Plumbing Repairs

While draining the entire plumbing system is not a part of any significant fix or enhancement to the plumbing system in your home. Still, it may be essential, like when the construction of an underground bathroom is being constructed, as well as the pipes over the installation must be flushed out. Once they are plumbing, pipes that are being installed will be connected to the current system. A large amount of water within the lines supplies water to the home. When the lines are being cut to connect to the new supply pipes, the water will flow out until they are removed.


Shut Off the Water Valve.

Turn off the main valve for water in the water meters.

Beginning at the top of the level, you should open all faucets for the sink. This will let air in the system. This helps to flow the water when you drain the system.

Open the Faucet in the Laundry Tub.

Take a trip to the basement or the lower level of your home and turn on the faucet of the laundromat or sink at the bottom. Let the water from the upper floors drain away.

Open the Tub or Shower Faucets.

Then, turn on all the shower or tub faucets.

Clean all toilets and empty the tanks.

Leave the Faucets in the Open Position

If you’re leaving your home unsupervised (such as when you leave an apartment for winter vacation), ensure the faucets are open. There should not be water flowing out of any faucet other than a residual drip from the bottom faucet when water from the pipes drips out.

If a house is left unattended for an extended period, the standing water in the sink traps, toilets, bathtub drain traps, and floor drains could evaporate, dissolving the seal on gutters that stops the sewer gases from escaping into the home. Experts recommend blocking toilet bowls and chutes by using wadded-up plastic wrap to ensure that the sewer system is shut off from the house when you are away for a long time. HTML0If you are planning to winterize, it is essential to soak up all water from the toilets or traps for toilets, tanks, traps, and any place likely to have standing water. As the water cools, it expands. This could cause cracks in the porcelain of traps, fixtures, or appliance fittings. This might not be necessary if your home is heated at a minimum. If the heat is switched off, you may also need to cover the water supply that is coming in with insulation and heat trace.

How to Charge the Pipes With Water

Reversing the water flow and filling the pipes with water is as simple as changing what you did to empty the pipes.

Close the Basement Faucet

Turn off the faucet in the basement or the tap at the lowest level in the home.

Close the Upper Faucets

Close all of the faucets that are on the top. Closing the taps allow air to stay in the pipes, allowing it to replenish the air chambers you could have in your plumbing system.

In this case, it is a good idea to shut off all faucets, except for the lowest one, like the laundry faucet. When you turn on or restart the system, it’s best practice to open the valve gradually and only halfway. When you have a consistent flow of water from your faucet for washing, close it and watch your system fill up and get fully pressurized. This is accomplished by listening to the water flow. If the flow is no anymore heard, then completely close the valve. If it’s a gate valve (round handle), it will be fully completed; you can turn it back 1/4 turn. The reason behind this is that old valves under pressure could fail when they are re-energized. Removing the valve can help prevent it from getting frozen (getting stuck) the next time it is used.

Open the Main Water Valve

Shut off the main water valve to allow the water to flow back to your pipe.

Turn on the Faucets

In a sequence, beginning with the highest-level faucets, then turn on the taps and let water and air sputter until only clear water comes out. There may be colored water emerging at first; however, this is normal.

Open Other Faucets

The shower faucets should be opened to let the water return into the pipes.

Flush the Toilets

Toilets should be flushed to replenish the tanks.

Turn off the Faucets

When the water is flowing clean, shut off the taps, begin at the top flooring level, then work through the home. Tapping may make a brief sound, but the pipes will soon eliminate any air left.
