What does TPR mean in water heater?
Your temperature and pressure relief valve (TPR valve) is a safety mechanism that only activates when the pressure/temperature inside your water heater tank is too high. When levels get too high, the valve opens and releases hot water to decrease the pressure inside the tank.
How does a TPR valve release water?
During a normal discharge from your TPR valve, water should release via the “discharge pipe” that runs down the length of the water heater. Which means, if everything’s working correctly, you should only ever see water dripping near the floor if your TPR valve discharges.
What is the tank on a water heater called?
Some water heater systems include a smaller tank called the “expansion tank”. This tank sits off to the side of your water heater and is designed to catch any excess water from the water heater tank. You see, as water is heated, it expands. And sometimes, as water expands after being heated, it outgrows the space within the tank.
What does it mean when your well water tank leaks?
Rather, your home's water is held in a pressure tank after it has been pumped out of the well itself. The well water tank maintains the water pressure in your pipes at a stable level, but if your pressure tank or valve is leaking, it may be a sign of a serious issue and you should investigate it immediately. Advertisement.
How does a water tank work?
The tank uses a pocket of highly compressed air to determine when your home's water system has reached its maximum pressure, at which point it sends a signal to stop the water pump – or start it up again if the system pressure drops below the minimum.
What Is a Well Pressure Tank?
Well water tanks are fairly simple in design. Basically it is a tank with an internal bladder separating the tank into two chambers; the lower chamber contains water, and the upper chamber contains air. As water flows into the bottom of the tank, under pressure supplied by the well pump, the air in the top of the tank is compressed, raising the tank pressure. When the tank reaches the set pressure level (called the cut-in pressure), the pump stops pumping water, and the air pressure in the tank pressurizes the water for the house. As the water is used and the air pressure drops to a low set point (called the cut-out pressure), the pump kicks on again and restarts the cycle.
Why is my water tank leaking?
The internal part of the hot water tank may be damaged. This is usually caused by a variety of reasons, such as a faulty tank or the tank not being properly maintained.
What causes your water heater to leak from the bottom?

What is the discharge tube on a water heater?
This is the discharge tube that is connected to the temperature and pressure relief valve (aka T & P valve). If the pressure builds up in the water heater tank, this valve will relieve the excess pressure and will look like your water heater leaking from the bottom.
What to do if a drain valve doesn't work?
If tightening the valve doesn’t work, the next step is to replace it with a new drain valve. If you leave it, the tank will continue to drain water and could result in water damage to your basement. To replace the drain valve, you will need to drain the tank first.

Why is my water heater brown?
Brown or discolored water – If you notice discolored water or brownish coloring in your water, there are chances your water heater has bad anode rods, and the tank is rusting from inside. Water impurities typically gravitate towards the sacrificial anode rod. If the anode rod is not replaced when it’s deteriorated, the harsh minerals in the water begin to eat away at the tank’s inner steel lining.
Why does my water heater make a weird noise?
You’d have to take a deeper look to find out the main problem. Your water heater could be overwhelmed by mineral deposits clogging valves. It might also mean your water pressure is fluctuating. The worst eventuality would be your water heater is breaking from the inside, and you need to replace it.
Why is my water temperature inconsistent?
It means the flow rate from the source is too low, or the heater can’t heat the water fast enough. However, where the heater has a tank, inconsistent water temperature is a sign of breaking water heating elements or a bad thermostat.
How to tell if a main seal is blocked?
Usually, dirt clogs the main seal. Find out if there is debris blocking the seal by opening and closing the valve a few times. Water should drip from the overflow pipe. Flushing should clear any dirt around the seal.
