Like most devices in the house, a water heating tank will last longer and operate more efficiently if it is given the proper care it needs. Most of the water tanks that we have today are automatic and this means that they call for minimal care. Rust on the outside can be tolerated but the internal rusting of galvanized metal tanks is bad. In this case, the galvanized metal has sides that are rough and these sides tend to attract the sediments from the water. Longer lasting, but more expensive, is the copper tank. Rust and grime will not be problems of yours when it comes to copper tanks.
Some people prefer to have glass lined water tanks. For this tank, the interior surface is lined with porcelain. For things like these, there are always alternatives to think about.
Every tank should have a regular schedule when it comes to draining. If the tank is not yet clean, you need to keep draining the water out. If you do not want to experience problems with sedimentary deposits then refrain from using hot water if you will be draining the tank. The tank should also be cool at this point. Try heating the water only up to 140 degrees. If there is no necessity for any hot water, there is no reason for the thermostat to be left turned up.
Here, the shut off controls are very important as well. The hot and cold water should never share the same valve. Some people have gas powered tanks and these units need a shut off control.
Check the off button. Do not go for something without a safety valve. See if this valve works automatically. Here, be certain that there is no pipe that faces upward when connected to the safety valve.
There are plugs that are available if your tank has leaks in it or you can also use a toggle bolt and a heavy washer. A leak can be more than just a leak. The seams might go any minute in this case. A minor issue in a leak can mean terrible things will come.
To be on the safe side, do consider regular draining when it comes to your tank. Here is where you need to drain the water out until the tank is clean. Prior to tank drainage, do avoid the usage of hot water and this is so that you will not have a problem when it comes to grime. The water in the tank should not be overheated. About 140 degrees will be hot enough in this case. If there is no necessity for any hot water, there is no reason for the thermostat to be left turned up.
