If you have a pond in your backyard, you may discover that it is no longer pumping water. After checking to make sure it has sufficient power and is plugged in, use the following three-step guide to troubleshooting the problem to see if you can easily fix it yourself.
Step 1: Check The Water Level
Although the water is pumped through the system using a propeller attached to the motor, water pressure and level come into play during this process. If the water is not above the intake and output valves, there will not be enough pressure built up to push the water through.
After locating the valves on both sides of the pump, measure the water's depth above the top portions. It should be at least three inches to allow for ripples or waves on the surface of the water.
If not, add water to your pond until the correct level has been reached. If your pump still does not work properly go on to the second step.
Step 2: Examine The Intake Valve And Filter For Debris
After checking the water level, the next step is to check the intake valve and filter for debris and dirt that could be keeping the water from reaching the propeller. You will need a screwdriver and an old toothbrush for this step.
Once you have located the intake valve, look for the clamp that attaches the intake hose to it. Use the screwdriver to completely open the clamp and remove it. Put it in a safe place, such as your pocket, so that it does not fall to the bottom of the pond.
After the clamp has been removed, take off the hose and look into the valve. You may need a flashlight to get a good view of the filter.
If you see any dirt or leaves on the filter, carefully remove it. A pair of tweezers can be useful for pulling it out without damaging it. Use them to pull on the sides a little at a time, alternating the sites until you can grasp it with your fingers.
Once the filter is out, use the old toothbrush to gently brush away any debris. Then, gingerly place it back into the valve, pushing around the edges until it is in place. After the filter has been cleaned and replaced, go on to the third step.
Step 3: Inspect The Intake Hose For Blockages
While you have the intake hose off from cleaning the filter, take the opportunity to check for any blockages. To do this, you will need to find the other end of the hose. Gently pull on it to pull it towards you. If you feel resistance, walk along the hose until you find what is holding it down.
Once you have both ends of the hose in your hands, place it on dry ground. Hold one of the ends up and place a funnel into it. Pour a gallon of water through the funnel and watch the speed at which the liquid runs out the other side.
If the water runs freely, replace and reattach the hose to the intake valve. However, if the water is sluggish or does not come out at all, something could be blocking it.
If so, use a pressure washer or garden hose with a nozzle set on a full stream to force water through the hose. This should knock loose whatever is causing the problem. Once you have tested the hose again, reattach it to the valve.
After performing the simple checks above, you may decide that the pump itself has malfunctioned. If so, you may want to replace the pond pump yourself or contact a contractor from a company like Kona Land and Water Escapes to do it for you.
