How to Clean a Condensate Pump

A condensate pump takes the water vapor that is produced in a heating and cooling system and sends it to a drain. Think of it as a dehumidifier for the system, as it removes the water from the air while the pump is operating. You may need to clean it from time to time to make sure that it lasts. They can get dirty and clogged up with debris. These steps will show you how to clean it.

Tools and Materials

  • Screwdriver
  • Clean Rag
  • Dish Soap
  • Mop Bucket
  • Bleach
  • Gallon of Water
  • Gloves

Step 1: Prepare to Clean

You will want to wear gloves for cleaning the condensate pump to protect your hands. Open the outer case on the pump. To do this you will need to remove the screws that are holding the case on. Use a screwdriver to unscrew them. Lift the tank and pump and pour the water out of both of them. You are now ready to clean it. You may want to have a bright light that you can hang so you will be able to see if you get all the dirt cleaned off.

Step 2: Be Safe

Some safety tips to remember: When you start to pour the water into the pump it will begin to run, so make sure you keep your fingers clear. Some condensate pumps have a water-level activated turn on. If this is the case, then you will have to fill the water up to a certain level before it will turn on. There will be wire sticking out from various points on the pump. Do not touch these while you are cleaning. You do not want to be electrocuted. Remember to try and start the cleaning process while the pump is off so that when you remove the case you do not chance injury when it suddenly turns on. You can get a good idea of how long you will have by observing the cycle ahead of time.

Step 3: Cleaning Solution

When working with bleach you need to wear clothes that you do not care about damaging. There will be some splash back when cleaning the condensate pump. Also, wear gloves to protect your hands. Create your own solution to clean the condensate pump. Mix 1/4 cup bleach and 1 gallon of warm water. This works best because the bleach ensures that it really gets clean and it kills bacteria.

Step 4: Clean it

Fill a bucket with water and dish soap. Use it to clean the entire pump with a dish rag. Next you will run the bleach water through the pump making sure that it runs through the lines and the pump. Use the whole gallon. Next, wash the bucket out and fill it with just plain water. Run the plain water through the pump as well, so that it is really clean. This may take a couple of times until all of the bleach and dirt is removed. You can now put the outer case back on.

Routine cleaning of the condensate pump is necessary to keep it running properly. If you follow the steps above, then cleaning it should be a breeze.
