Why Should I Flush My Water Tank
Most hot water tanks have a significant holding tank that ensures there’s plenty of hot water available when it’s needed. However, because water is sitting in the tank continuously over time, naturally occurring minerals in the water, as well as sand and grit flushed from municipal water lines, can settle in the bottom of the tank.
The sediment build-up can potentially make it harder for your hot water tank to do its job. This puts your water heater at risk of failing sooner than it should. Hot water tanks should have a life span of 10-12 years at least, but not annually draining the sediment can reduce that life span significantly.

Inspecting Your Hot Water Tank
This is also a good time to inspect your water tank. You’ve already checked your T& P valve and we know that the drain valve and burner controls are working. What about the body of the tank?
Take a good look over the body of the water tank particularly the bottom. Do you see any “blisters” where it looks as though it’s beginning to rust? Is there any water dripping from anywhere or wet spots underneath that may be signs of your tank leaking? If so, you may want to begin preparations for getting a new tank. When the tank finally goes, it can be messy, inconvenient, and even cost more if you have to pay for emergency service or don’t have time to shop around.
“Foilback” insulation is one type of insulation that can be used though the “R” factor is a little lower than some others.
Back Flush The Water Heater
Back-flushing the water heater should help you solve the clogged drain valve issue if neither the stiff wire method nor the stomp-on-the-hose trick works.
You will need a washing machine fill hose for this step. Close the hot water tank drain valve and connect it to one end of the washer fill hose. Next, extend the washer piping and secure its other end to a nearby faucet. You can also secure the second washer port to a garden hose running from a backyard tap.
Ensure the connections are water-tight to create sufficient water pressure before opening the faucet. Then, open the tank drain valve for about 15 seconds to push the obstruction away from the drain valve.
Close the faucet and the drain valve and disconnect the washer fill hose from the water faucet. Open the drain valve, and continue draining.

Shut off the drain valve and disconnect the garden hose. Be sure all but one of the hot water taps in your home are closed .
Now you can turn the water back on to the water heater. Re-energize the system slowly by partially opening the valve. Once the system is fully energized, open the valve to a fully open position.After doing so, monitor the tap you left open and, once you are getting nothing but water out of the fixture, turn it off.

Can I Unclog The Bathtub Drain Myself
Some do-it-yourself solutions may offer temporary results for a clogged bathtub drain.
First, you can try to use a sink plunger over the drain to unclog it. This creates a vacuum of air that can dislodge whatever is clogging the pipe, such as a wad of hair. You can also try your hand at using a drain snake, which is a long piece of silicone or wire cable that you weave down into the pipe. As you pull the drain snake back up, it will attach to items and unclog the drain.
Both of these items are found in most home improvement stores and are relatively easy to use.
Another at-home trick to try when your bathtub wont drain is to pour boiling water. This will help to melt soap scum and hair build-up to unclog the drain. But this tactic will only work if the boiling water can be poured directly into the drain opening.
You can also try a baking soda and vinegar mixture to clean out clogged bathtub drains. First, pour boiling water down the pipe. Then pour in about half a cup of baking soda followed by a cup of white vinegar into the drain. When baking soda and vinegar are mixed, they create a chemical reaction that foams up. This creates pressure within the pipes, which can push the clog further down so it does not block the drain.

The methods for fixing a leaking water heater can range from very easy to highly challenging. At the first sign of leaking, many people leap to the conclusion that the water heater must be replaced, but that’s not always necessary. Many potential fixes are actually rather simple and inexpensive, and sometimes replacing a broken part can extend the life of the water heater for several years. Here are several things to look for when diagnosing the source of a leak and determining the proper fix.
Look At The Water Supply Lines
The first place to check is the plumbing pipes above the water heater. A drip from above can easily leak down on top of the water heater and even work its way down the insulation and make it look like the leak is coming from the tank itself.
Check the plumbing pipes above the water heater, using a stepladder if necessary. Pay special attention to the water supply lines going into the water heater. These may be rigid pipe connections or flexible supply tubes. Flexible water supply tubes are the most common cause of leaks above the water heater since it is common for these tubes to fail long before the water heater is ready for replacement. If there is insulation around the supply tubes, remove it so you can inspect and replace the tubes if necessary.
To replace the water heater flex lines, shut down the heater first by turning off the gas or the electricity running to the heater. For gas heaters, the instructions to turn the gas valve to the off position are typically on the front of the tank. For electric heaters, you can usually use a disconnect switch at the heater or a separate breaker to turn off the power.
