Can a Hot Water Tank Be Repaired?

Jun 1

Before calling an appliance repair service, make sure your hot water tank is not in need of major repairs. If you notice rust on the tank's outside, it may be an indication of a leak that needs to be repaired. The rust might be caused by corrosion inside the tank or it may have a leak on the outside. In either case, it is best to have it repaired before it causes more problems.

Repairing a hot water tank

A hot water tank typically lasts for eight to ten years, but if you live in a climate that fluctuates between extremes, your water heater can leak and cause a serious problem. In these cases, homeowners may decide to replace the unit, but it is possible to repair it yourself if you have the right equipment and know how to do so properly. While a professional will most likely be more expensive than a do-it-yourself project, there are some signs that you should watch out for.

If you have a welding torch, you can repair the leak by soldering a pipe to a tank. Copper pipes usually leak where two copper pipes meet. To solder the pipe joints, you must first drain the tank and disconnect it from the main water supply. Before you start soldering, you should apply a thin film of flux to the metal. The temperature should be set at a medium setting to prevent contamination.

What might help give the tank longer life is installing a water heater timer.

Cost of repairing a hot water tank

If you're in the market for a new hot water heater, it's time to look into the cost of repairing a hot water tank. There are a few parts you can do yourself to save money. Purchasing an anode rod, for example, will cost between $20 and $50 and will prevent your tank from corroding. Plumbing professionals recommend replacing an anode rod every five years, but you can also do this repair yourself if you know how to properly do it.

One important part of a water heater is an expansion tank, which prevents pipes from bursting in case of a failed tank. Older homes may not have them, but newer construction often requires them. Installation of a new expansion tank will cost anywhere from $40 to $350. Additionally, you'll have to remove the old tank, which will cost between $100 and $500, depending on the contractor. If your water heater is large, it will cost more.

The most common problem with a water heater is leaks. When water starts to leak, it will corrode the tank and create microscopic cracks. Water leaks aren't always an indication of a faulty water heater tank, however. The leaks may be coming from the hot water out pipe or loose connections on the top of the unit. Getting a plumber to inspect your tank and determine the exact cause can save you a lot of money in the long run.
