Why is my water expansion tank leaking?
Your thermal expansion tank is likely leaking for one of two reasons. The first possibility is that the point of connection between the hot water tank and the expansion tank is loose, causing the tank to leak and corrosion at the connection point. Alternatively, the rubber bladder inside the tank might have corroded over time, causing leaks from within the water heater tank itself and rendering it useless.
Should I turn off my AC if it's leaking?

How to fix a clogged drain?
To fix the issue, you need to flush the drain line until the clog is removed. High pressured air, or hot water is often used, though some chemical drain cleaners are also employed. After the drain is unclogged and flowing freely, you should investigate what causes the clog to prevent it from happening again.

Gurgling sounds when AC is running. When the air conditioner comes on, the blower fan in the evaporator unit creates a lot of airflow. This pressure can actually suction up water from puddles inside the unit, causing it to gurgle and splash.
What does a portable air conditioner do?
Portable air conditioners also use a drain line or a collection tank. If the tank is not emptied in a timely manner, it can overflow, resulting in a water leak. However, most modern units have sensors that will shut the unit off if the tank gets too full.
What happens if your AC drain line is loose?
Even if your A/C is installed correctly, it’s not unheard of for the drain line to become loose over time. If it gets loose enough, it can completely disconnect from your AC, which will cause leakage. 4.
Why does my A/C drip pan freeze?
Low refrigerant can make the A/C coils freeze, which can then cause leakage as the drip pan overflows. 6. The air filter is dirty. When the air filter becomes dirty, airflow is restricted and the evaporator coils don’t get the ventilation they need. This causes the coils to get too cold and eventually freeze.
What happens if a condensate pump is broken?
The condensate pump is broken. If your condensate pump is broken, it can’t pump out the excess water in the condenser pan, so the pan will fill up and start overflowing (or leaking). 5. The refrigerant level is too low. Low refrigerant can make the A/C coils freeze, which can then cause leakage as the drip pan overflows.

As the warm air from your home is drawn in your HVAC unit, it is blown over the cold evaporator coils, which causes it to condense, thus making it less humid.
What is the line that drains water outside?
The resulting moisture drips into a drain pan that leads to a condensate drain line. This line leads out of your home and drains the water outside.
Why do air conditioners have a cutoff switch?

What causes evaporator coils to ice up?
Low refrigerant levels – If your refrigerant levels are low, the pressure in your AC system will lower as well , which can cause the evaporator coils to ice up. If those coils freeze, your drain pan may overflow and leak water.
Is it normal for an air conditioner to puddle?
Take for example, your home in Montgomery, Frederick, or Howard County. If you come home to find a small puddle of condensation near the drain pipe, that is normal and a common effect of an air conditioner working hard —particularly on extremely hot or humid days. Likewise, if a small puddle is found underneath your air conditioner’s condenser unit, this is most likely a result of your unit’s normal operation.
