Question about Samsung AW0505M Air Conditioner
The likely reasons for a leaking AC are...
1) Improperly installed.
A window air conditioner must be slightly lower at the rear than the front. This allows the water being removed from the room to drain to the back of the machine. A difference of one inch is sufficient. This is always the first thing to check. Many are improperly installed in the haste to get relief from the heat. If installed too low at front the water will flow into the room rather than outside. If installed too low at rear, water can roll out front edges before has chance to exit towards rear drain.
Water being de-humidified can turn to ice if there are problems with the cooling system. There are many reasons for an air conditioner to produce ice. Remove front grille while machine is operating. If ice is present on the cooling coil you will probably need service. For more information see our other article: Why window Air Conditioners Ice up.
If warm air is able to enter around the air conditioner it will encounter cooler, dryer air. When they meet condensation will occur. If water leaking from front of air conditioner inspect to see if dripping from body of machine, or water droplets clinging to front area. To test, operate machine for 30 minutes and then use flashlight to check under front edge of base. Small water droplets here indicate an air leakage problem. Add foam insulation to stop warm air from infiltrating.
Rear of air conditioner base has a drain hole or groove to allow water to escape. If becomes blocked water can back up. To test, operate machine for 30 minutes and then inspect if draining properly. If appears blocked use a small piece of wood to open drain hole at rear of metal base. CAUTION: Never be tempted to drill holes into the air conditioner body to relieve water pooling. Severe damage can result.
There are small passageways that allow water to drain from front of air conditioner to the rear. If they become blocked water will pool at front of machine and overflow onto floor. If this happens the air conditioner will require removal from window and servicing.
This occurs at end of cooling season. If outside temperatures drops below 60 degrees Fahrenheit at night the cooling coil may ice up. If no leakage at bedtime but water in front of machine in morning, suspect this problem. If this problem suspected turn off machine before bedtime and restart as day warms. Alternately, operate machine at night with selector switch in ‘fan only’ position. This will circulate room air during night but not allow cooling.

Hot water pressure relief valves serve two functions. The first is to remove high-pressure water from the hot water tank. The second function is to act as a high temperature valve to remove water that exceeds a predetermined point for the valve. Both of these relief settings are preset at the valve factory. Many pressure relief valves will come with a metal tag that identifies these release points. If you're attempting to remove the hot water heater pressure relief valve, pay careful attention to ensure that you replace with the correct valve.
Your hot water heater has a pressure relief valve safety mechanism. When pressure inside the water tank exceeds certain limitations, the valve opens up to allow the pressure to be released. A faulty pressure relief valve will not release excess pressure, which could cause extensive damage to your home. You should test the hot water heater pressure relief valve once every six months to ensure proper operation. If the pressure relief valve fails the test, replace the valve with a new one immediately
Locate the pressure relief valve on your hot water heater. The pressure relief valve has a lever handle on top with a drain pipe attached to it. The pressure relief valve is most often on the side of the water tank toward the top. Newer models of hot water heaters have the pressure relief valve on top of the water tank.
Inspect the area around the pressure relief valve for signs of leaking water. If there is leaking water near the relief valve connection, replace the relief valve. If no leaking is evident, proceed with testing the pressure valve.
Examine the area below the pressure relief valve drain pipe. Most water heater closets either have a drain in the floor below the pipe or the pipe is inserted into another pipe to direct the water out of the home. If the end of your drain pipe is not in another pipe or there is no drain in the floor, place a bucket under the drain pipe to catch water when you test the pressure relief valve.
Pull the lever handle on the top of the pressure relief valve up with your fingers. A working lever will lift up without difficulty.You should begin to hear water going through the drain pipe. Slowly release the lever to shut off the pressure relief valve. The pressure relief valve is good. If you did not hear water running through the drain pipe, lower the lever on the pressure relief valve and replace the valve. If the lever is difficult to raise, do not force the lever. Replace the pressure relief valve.
