Problems and Solutions

The T&P Valve Isn’t Tight Enough

The temperature and pressure relief valve or what is more commonly referred to as T&P valve may not be tight enough that’s why hot water is leaking from the top. This valve is located at the side of the tank. Take a look at it and see for yourself if there is any water you can spot. For you to be able to tighten it, you will need to drain your heater until below the valve and then remove the valve. If the valve already has rust or any signs of damage, then you will need to replace it, but if it not, then you can just put it back and tighten it. If you can’t, then ask the help of someone who can really tighten it for you.

The Pipe Fitting is Loose

Another thing that you need to check is there is a leak on your inlet or outlet pipe. Check the specific part where the pipe connects to the heater. If you see any lose pipes, all you need to do is to tighten it with a wrench. However, if the leak is really strong and the pipe is really loose, then it might burst. So, in this case, it is best you call your plumber to fix it to avoid making the problem worse.

Rust or Corrosion

An old water tank will have rust or corrosions on top that can cause leaks. This can happen because of poor dielectric connections on your pipes and tanks. Now, if the problem is really bad, for instance your water heater has rust all over the top of it, then you will need to ask the aid of a professional plumber to see how much can be fixed and if there is anything that needs to be replaced. Remember that rust and corrosion may grow or scatter so it’s best to replace it especially if the rust reached the heater already as opposed to rust found on pipes alone that you can still replace individually.

Conclusion

As you can see, hot water tank leaking from the top may be due to many reasons. Before calling and paying for the help of a professional plumber, it would be great to investigate on the problem alone first. This way, you won’t need to pay for extra expense.
