Before doing any maintenance on the fountain, turn it off. 

The first step is to switch off your fountain’s water pump. This is necessary to prevent water from spraying everywhere when you begin cleaning. This pump, as well as any other tiny ornamental things you may have inside, must be removed.

Remove the water from the fountain and dispose of it.

The fountain must then be emptied. After all, going back to the beginning is the simplest method to keep your water crystal pure. A clean slate means you may take all the required steps to guarantee safe, long-lasting water. 

Taking Out the Water

Algae and other debris are more likely to grow up and stay in the vessel if unclean water is allowed to dwell within.

Emptying the water from a fountain is a simple task that may be accomplished in one of many ways:

  • Unplugging the fountain entails removing the plug at the base and enabling drainage.
  • Bucket by bucket: removing the water with a little bucket.
  • Water siphoning: Using a short piece of tubing, siphon water to the ground.

You should be able to see the grit and filth left in the base after you’ve finished this step. In the following stage, we’ll look at removing this.


Clean up the Fountain

After that, we must get rid of any residual extra. The following are some of the most prevalent ways of dirt/algae removal: 

  • a solution of household bleach and fountain water
  • a stiff sponge, water, and a regular dish soap
  • Cleaner for fountains (make sure it works for copper fountains)
  • Cleaner for stainless steel (for stainless steel fountains)

You may also use a sponge to clean any excess ornamental pieces to ensure that they don’t have any invasive algae or dirt that might hinder your progress.

You should be able to inspect every section of the fountain after the water has been drained and it has been cleaned. It is now safe for you to proceed to the next stage.

Check for clogs in the pump.

Dirt, leaves, and other natural detritus that come with an outdoor site sometimes block water pumps. As a result of the inadequate water circulation, the liquid becomes a gorgeous colour of brownish-green.

Cleaning the pump using a tiny washcloth or towel is a simple option. This should be done on a regular basis to minimize calcium accumulation and allow free flow of water. However, there are situations when there is more to it. A natural obstruction might be the problem.

Blockages may occur from a variety of sources, including:

  • Leaves: They may clog the pump, no matter how big or little they are.
  • Dirt: This usually collects near the fountain’s base.
  • Rocks: They might be little or enormous.
  • Wrappers, paper towels, and plastic bags are examples of household waste.

You can take these things out by hand, but if there seems to be an impediment deep within, it’s probably preferable to clean it using a homemade solution. This will clear the path for optimal water circulation by removing any inaccessible impediments.

The following are some options for clearing a blockage:

  • White vinegar: This dissolves undesirable buildup rapidly.
  • Water and soap: Use the same approach as vinegar, but with less strength.

Both of these products may be used with a toothbrush, allowing you to reach the deepest sections of the pump without difficulty. Pipe cleaners may also be used.

Fill the bottle with distilled water.

Distilled water is the finest choice for your fountain. Because it’s clean water, this method works best. Because the pump has an easier time pushing it through, it will last longer and clean your water for a longer period of time.

Distilled water is available at almost every grocery shop, petrol station, and hardware store. It’s inexpensive and will maintain your fountain in tip-top form.
