Why is My Swamp Cooler Dripping Water?
It may seem alarming when you notice water dripping from the roof, especially in summer. Where’s that water coming from? Your swamp cooler!
Before you worry, keep a couple of things in mind; there may be nothing broken or damaged in your air conditioner.
Swamp coolers function by running water over pads that water is forced through in order to cool it off. This requires a pan, a pump, a float and a source of water. If too much water is in the pan or working through the mechanisms, some swamp coolers have overflow pipes. Condensation and too much water in the system will lead to a drip.
This overflow is normal! If it happens occasionally, it just means there’s a little more water in the air conditioner than normal and it’ll equalize. However, if you see it repeatedly, you may be getting too much water in the pump. A float controls the water intake and it’s meant to stop the pump from dealing with too much water. If the float isn’t functioning correctly, this can lead to overflow. Check the float and adjust the metal arm holding it.
Another frequent source of drips in swamp coolers is the drain pan. It usually holds the water that the pump utilizes to wet down the pads. If this pan has a crack or is compromised in some way, it may drip.
This won’t interfere with the function of your swamp cooler as long as the water source is uninterrupted, but it can increase the amount of water your air conditioner uses. If you see a crack or notice the drain pan has visible rust, call R &R Heating & Air to schedule a repair!
