If water is dripping, pooling, or showing up where it should not, note where it appears and when it happens. Those details help narrow the leak faster.
Leaks often come from the float valve, water line, drain, reservoir pan, mineral scale, or pads that are not seated correctly.
A swamp cooler uses water constantly, so a small leak can have several causes. The most useful first step is to describe exactly where the water appears and whether it happens while the cooler is running.
You do not need to identify the failed part. These signs help you explain the leak clearly when you call or request an estimate.
If the float valve sticks or the reservoir fills too high, water can overflow instead of staying inside the cooler.
A small supply line, fitting, or distributor tube can loosen, crack, or clog, sending water where it should not go.
A blocked drain, bad overflow connection, rusted pan, or cracked reservoir can leave water near the base of the unit.
Hard water can clog pads, lines, and distributors. Water may spill or run unevenly instead of soaking the pads correctly.
Pads that do not sit correctly can let water bypass the media and leak around the frame.
For roof-mounted or side-mounted coolers, note where water appears. That detail can help separate a cooler leak from a roof, flashing, or drainage issue.
Turn off the cooler and the water supply before working on it. If water is entering the home or near electrical parts, stop using the cooler and call. Skip roof work in wind, heat, or wet weather.
Note where the water shows up: under the cooler, down a wall, around the roof curb, at the drain, or inside the home. The location usually points to the part.
If water runs out of the overflow tube constantly, the float valve is set too high or stuck open. Bend the float arm down slightly or adjust the float so the water stops a little below the top of the overflow.
Check the overflow and drain fittings at the bottom of the pan. A loose fitting or a cracked overflow tube drips even when the water level is right.
Follow the small supply line to the float valve and tighten a dripping compression fitting a quarter turn. Replace a cracked line rather than taping it.
Look at the bottom of the pan for rust spots or pinholes. A pan coating can seal small spots, but a pan rusted through usually means repair or replacement.
Check that the pads sit fully inside their frames. A pad that slipped out of place can drip water outside the cabinet.
If water leaks only while the cooler runs, the distributor or a loose hose may be spraying water past the pads. Reseat the hoses and clear the distributor.
If the leak is at the roof curb or water is getting into the ceiling, call. Roof flashing and curb seals are a job for a technician.
Water problems can damage roofing, walls, ceilings, or cooler parts if they keep going. A leak is worth handling before it spreads.
Water is dripping from the cooler or pooling near the unit Water shows up inside the home, near a ceiling, wall, or vent The cooler leaks whenever it turns on The reservoir appears to overflow or the pads look soaked unevenly The leak comes with weak cooling, musty smell, rust, or unusual noise The leak location and timing are the two most helpful details.

Get help when your cooler blows warm air, leaks, makes noise, or will not turn on.
Clean, inspect, and tune up your cooler before heat, scale, or worn parts cause a breakdown.
Replace worn or mineral-clogged pads so your cooler can move more air and cool better.
Common causes include a stuck float valve, high water level, cracked water line, clogged drain, rusted pan, loose fitting, mineral scale, or pads that are not seated correctly.
It can be. Call sooner if water is entering the home, spreading near electrical components, pooling on the roof, or leaking every time the cooler runs.
Yes. Mineral scale can clog lines and distributors, which can make water spill unevenly or overflow instead of soaking the pads correctly.
If water is pooling, entering the home, or near electrical parts, stop using the cooler and request repair help. For a small drip, still describe when and where it happens when you call.
Yes. Worn, clogged, or poorly seated pads can let water bypass the pad media and run around the frame.
If water is showing up where it should not, call or request an estimate and describe exactly where the leak appears.
