The 4 guidelines that the water heater will be on its final stage:
1. How old is the water heater - The serial number in the water heater had the date when was the water heater has been manufactured. But it will not look the ways the date has been normally written. As a substitute, a serial number may have the date code like the "F051052638".
The F stands for the month, since F is in the 6th letter of the alphabet, and so it denotes that it is the 6th month of the calendar and that is June. Then, the primary two digits in this serial numbers are 05 that represented the 2005 year. So the water heater has been made in 2005 of June. Each manufacturer had the same date code, and this will vary or check the website of the manufacturer.
Normally, most water heaters which are more than ten years old in age should be taken into consideration for replacement. When the water heater has been in the location that may not cause damage when there is the leak, you may wait until it will develop the leak before finally changing it; however, that is not really recommended. When the water heater is at the location that may cause the damage to the home, you must strongly take into consideration changing it after ten years or even before 10 years, if there are any other symptoms that will take place.
2. Rusty water - When you have the galvanized pipes, you may have these rusty pipes. The best test to avoid changing your still functioning water heater will be to drain the few 5 gallon hot water buckets of a water heater. In the third bucket, when the water coming from the heater has been coming out rusty, so, most likely that the water heater is at fault and it is really not the piping.
3. Rumbling and noise – If this will happens, you will often hear banging sounds or rumbling coming from a water heater since it will be heating up. It is the sign that a water heater is in their final useful life.
The layer of this hardened sediment will mean less efficiency and more damage too.
4. Water around its water heater – when you notice the moisture around the water, you can have those small leaks or there is a fracture within the tank. As a metal gets heated, it expanded and when there are some slight fractures, the water will leak from your tank. The moment the metal has been cooled, its inner tank may stop leaking.
On the other hand, before finally replacing the water heater, be sure that there will no other leaks that are coming from either its connections or fittings to the tank. Make sure also that the pressure or the temperature overflow pipe are not leaking as well. When all of your water fittings and water connections are totally dry, then this is the time to change the water heater.
Better call a plumbing service and let the expert do their job, calling them early as possible can lessen the cost and the time.
