How To Drain A Water Heater Without Drain Valve? Water heaters have provided relief to many families for many years. This is the most widely used and most neglected device. Its functionality may seem irrelevant until it collapses.
This is why it is important for you to give your water heater the maintenance it deserves.
Therefore, it should be drained at least once a year. But what if the drain valve fails?
After reading this article, you will know how to drain a water heater without a drain valve. There is nothing to prevent you from clearing up any sediment that may have accumulated on your water heater.
First, let’s break down the important parts. So we’ll show you how the system works and what the hose looks like to drain the water heater without using a drain valve.
An essential part of the water heater
To understand how the entire system works with a water heater, it is important to know the basics.
Its main purpose is to release toxic gases, including carbon monoxide, during the combustion phase.
At the end of the fume hood, there is a fitting called the train deflector, which is responsible for collecting various gases discharged from the fume hood.
Pressure and temperature limiting valve.
This is also known as a T & P valve. Water tanks release excess heat and pressure to prevent explosions. If you continue to download this part, we recommend that you replace it.
Hot water outlet.
Hot water can escape from the water heater through this outlet. Then it goes into the drinking water supply of the house.
Coldwater shutoff valve.
When the water heater itself is replaced or emptied, this part of the water heater shuts off the supply of cold water.
This pipe is connected to a temperature and pressure relief valve. When the T-valve and P-valve release additional steam from the heater, water can safely flow out of the heater through this pipe.
Anticorrosive Anode Rod
This is also known as the sacrificial anode. For water heaters, this is the most important part. This rod is usually made of aluminum or magnesium with a sturdy steel core. This barrel usually corrodes before other exposed metal parts. Do not remove this barrel from the tank unless the manufacturer requires a warranty.
This part is connected to the cold water inlet that reaches the bottom of the tank. Due to its self-circulating properties, solids do not settle to the bottom of the container.
These are usually found in electric water heaters. They are responsible for heat transfer to the water heater.
All tank types have this part that retains the heat inside the tank.
Control valve or thermostat.
It is responsible for controlling the amount of heat in the water heater.
This ignites the propane or natural gas in the tank and heats the water in the tank.
Gas supply valve
It acts as a block of gas elements in a water heater.
This part is useful for monitoring drafts. The gas valve also prevents gas from flowing between the main burner and the pilot flame.
This valve is located at the bottom of the water heater in the tank type category. By the name itself, this helps to empty the entire tank.
What is the drain valve of a water heater?
The drain valve is the valve below the heater of the water heater. When the system is drained or cleaned, water is removed from the entire system.

Remove the broken drain valve and make sure the heating area that supplies water is turned off. Also, make sure that the hot water valve is closed. If the heater has a plastic drain valve, insert a self-tapping serrated insert to lock the nipple in place and loosen the screw.
Even better, you can drill a hole in the drain valve with a hand drill. Do not use a drill to prevent electric shock due to water droplets when drilling.
If the heater nipple hole is made of brass, you can make a cross-section with a hacksaw blade. Then drill the cut with a screwdriver and turn the screwdriver clockwise.
You can then insert the garden hose into the opening and place the other end of the hose in a bucket to start draining. Carpets prevent water from spilling onto the floor.
After draining, leave the T and P valves open to allow the air to dry the water inside. And now you’re done.
Why do you need to empty the water tank?
Emptying the water heater is part of its regular maintenance. Over time, our water heaters accumulate with dirt and other deposits. Aside from dirt, the tank corrodes and the corrosion remains on the bottom of the tank. This can lead to tank clogging in most cases.

Cool the water tank so that it does not move with boiling water. Open the hot water tap in the sink to improve the process. Now that the stove burner has been switched off, cold water is replaced by draining hot water from the kitchen faucet.
Run the kitchen faucet throughout the washing process. This will prevent the line from being sucked in when the hot water is drained.
Connect the hose to the drain valve and make sure the other end of the hose is connected to a bucket or other place where water can drain into the sewer or street. If your water heater is in the basement, consider purchasing a pump to bring water from the basement to the ground floor.
Turn off the cold water inlet valve above the tank to allow all household hot water to do this without interruption. Even better, you can put water where it goes into your house. Therefore, these valves need to be discovered before starting the entire cleaning process.
Turn on the tap to start draining. However, make sure the other end of the hose is wired or connected to the bucket. However, if you are in the basement, you will need a water pump so that you can pump water from the basement to the ground floor.
How to Flush a Water Heater?
The right time to flush the water heater is when the tank is empty or the drain is almost empty. Follow the steps below to wash the water heater.
Open the chilled water inlet valve, let it flow into the tank for 15-20 seconds, then turn it off. This helps pull out the sediment at the bottom of the tank.
Next, check the hose and outlet water samples connected to the drain valve. If the water is dirty, the entire cleaning process should be restarted until the water coming out of the heater is clean.
When you run out of clean water, close the drain valve and open the water valve. Then disconnect the hose and wait until the tank is full.
Air must be trapped in the system while the water is being drained. Next, open the hot water tap to remove air from the water pipe. Air is coming out of the faucet. If the water keeps coming out of the faucet, you can turn it off.
After all, setup is complete, you can reignite the burner. Do this when the tank is full or half full, as turning it on at least early can cause damage. The water is cold, so the burner will start immediately.
If you have a microwave, turn on the switch to turn the heating back on. When this is done, you should feel the faucet temperature rise within the next 30 minutes.
How to Drain the Electric Water Heater?
To drain the electric water heater, perform the following steps correctly.
The first step in draining an electric water heater is to turn off the heater power switch. To do this, you need to disable the circuit breakers or fuses that power the system.
Then turn off the water source that supplies the heater with water. This valve is located at or near the chilled water inlet pipe above the heater. To switch it off, turn the clock clockwise. If you can’t find the valve, the second option is to send the main water valve back home.
You can now drain it. Find the drain cock on the bottom of the heater. It is usually silver or brass and has screws on the ends. You can put a bucket under the drain valve or, better yet, attach a garden hose to it.
Open the pressure and temperature valves to release the pressure from the tank. You can find it on the stove. Move the lever up to open it.
Now let’s drain the water into the tank. The tank can be partially or completely emptied. For partial drainage, leave a few liters of water in the pipe or. However, to completely empty the tank, it must be empty.
When draining is complete, close the temperature and pressure (T & P) and drain valves. Then turn the water heater back on.

Replacing the water heater drain valve without draining the water heater is not as difficult as you might think.
If the drain valve is clogged, you can empty the water heater. In this case, the best response to a clogged drain valve is to install a ball valve.
