It may be that the moisture or water honeycomb padding is cracked, allowing the water to escape. The issue may persist if it remains unfixed for a longer time.

Luckily, the article describes the common causes of the issue and gives the best steps to fix it successfully. Also, it includes the frequently asked questions concerning the swamp cooler base that is leaking. Therefore, ensure you fix the issue instantly or seek help.

Common causes of Swamp Cooler Bottom LeakingCommon causes of Swamp Cooler Bottom Leaking

Most people may experience the issue of the swamp cooler bottom leaking. These are the most prevalent causes of an air cooler that leaks.

  • The honeycomb pad is faulty

When washing, the honeycomb pad, commonly known as the water-soaked pad that the air flows via, may become faulty or fail to function as usual. It may be unable to contain water and spill it all over your ground due to this. In such circumstances, it is important to solve the issue immediately before it becomes worse and damages your floor.

  • Overflowing

You may have overloaded your swamp cooler or air cooler, which is causing it to leak water. The ice chamber on models with an ice chamber may have already melted and overflowed.

  • A leaking water tank

If the water is pouring from your swamp or air cooler base, the water storage tank may leak it. Although corrosion will not be a concern because most water tanks are made of plastic, unintentional perforating during washing or installation may occur.

  • The honeycomb pad has incorrect fittings

It’s possible that if you place the honeycomb pad improperly, it can spill water. Additionally, if you purchase a repair pad in the incorrect size, it may not absorb the water properly.

  • Open water

If the water tank is not returned to its appropriate places, water may escape. Devices with a removable water tank are more prone to issue of leakages.
