Take your channel lock tool and unscrew the valve. You need to get air into the tank, so open up a hot water valve nearby. If you’re confident in your abilities to tackle this problem, start by turning off the water supply to the unit and drain the tank until the water is below the level of the valve. If you see water leaking from the threads of the valve, you’ll have to remove it and replace it with a new one. Once triggered, steam will escape, allowing the pressure to return to normal. This is a safety feature that is triggered when there is too much pressure in the tank.
The temperature and pressure relief valve (T&P) is sometimes located on the top of the water heater tank.
If you tighten the nut and you find that the valve is still leaking, it’s probable that the valve itself is now malfunctioning completely and needs replaced. If you’re lucky, it’s just going to be a loose fitting around the pipe, which means you only have to tighten the nuts that connect to the handle. If you see water pooling on top of your unit, it’s a good sign that your inlet or outlet pipe are leaking.

This is also an easy task unless your fittings are copper, which means they have to be joined with solder, which is almost always a task for a professional plumber. Corrosion will be best dealt with by replacing the fittings. This might completely stop the leak, solving your problem.Īlso, corrosion in this area is not uncommon. You can take a wrench and try to tighten the fittings. This is a common area where water leaks, and you’ll generally see the leak at the point where the fittings meet the water heater. Look closely at the water inlet and the outlet fittings. So, let’s look at some of the most common reasons your water heater is leaking at the top. Water takes the easiest path of resistance, which means any water coming from the top will travel down the side of the tank, which is what causes the electrical shorts and other water damage problems, which is why you want to call a professional as soon as you see a problem. The good news is that when you catch your leak quickly, it’s almost always a repairable scenario. And don’t think that just because your water heater is leaking that you’re not going to have to replace the entire unit – it could be a simple fix. One thing is certain – if you don’t fix the leak, you’re going to see other problems as a result, including possible electrical shorts in your heater and water damage to anything in the immediate vicinity. But, what’s causing that leak and how can you fix it? That’s not to say that a water heater leaking from the top is a good thing, but it is preferable to a bottom leak. If your water heater is going to leak, you certainly don’t want water coming from the bottom of your unit.
