A water fountain adds tranquility and an active decorative feature to your home. The water catches the light and the continuous flow of water mimics a brook or tiny waterfall, blending the vitality of nature with your home environment. A fountain that's too loud or a fountain pump that makes more noise than the water requires cleaning, adjustment or replacement. Examining and caring for the pump may quiet the fountain.

Caring for your fountain keeps the fountain's pump running smoothly.

Step 1

Check the fountain's water level. Keep the water level at least 1/2 inch above the top of the fountain pump's housing. A low water level contributes to noise by allowing excess air into the pump and can cause the pump to burn out.

Step 2

Unplug the fountain pump and remove it from the fountain. If the fountain pump isn't visible, remove the decoration that's hiding it. Fountain designers often hide the pump under a decorative feature such as a slate platform or piece of bamboo. Gently lift the decorative item out of the fountain to expose the pump, then remove the pump.

Step 3

Remove the fountainhead or tube from the pump if it has one. A fountainhead or tube is an attachment that directs the flow of water. Grasp the base of the fountainhead directly above the pump and gently pull it out. Rinse the fountain pump and fountainhead under running water.

Step 4

Immerse the pump and the tube or fountainhead in undiluted vinegar to remove mineral deposits. Keep the power cord out of the bucket -- leave it hanging over the bucket's edge. Leave it to soak overnight.

Step 5

Flush the fountain pump and fountainhead under running water to remove any remaining debris. The vinegar dissolves mineral deposits that can build up in a fountain pump and affect its operation.

Step 6

Wash the fountain basin and any rocks or decorative parts with water and mild soap such as dish soap. Remove any materials that show signs of deterioration. If sandstone, shells, driftwood or other materials deteriorate, the debris can damage the pump.

Step 7

Check the fountain pump for a flow-rate switch. It's usually located on the side of the pump and often indicates "S" for slow and "F" for fast. Move the switch to the "S" position. A slow rate of water flow makes the fountain quieter. Not all fountain pumps have adjustable flow rates.

Step 8

Rinse the fountain basin and decorative parts. Reassemble the fountain. If the fountain pump has suction cups, pour 1/4 inch of water into the basin and press down on the fountain pump to engage the suction cups. Securing the pump reduces vibration and noise.

Step 9

Replace the fountain's decorative features. Plug in the fountain. If the fountain still makes too much noise, shop for a pump designed for quiet operation.
