Troubleshooting

There is less sand flowing thru the SandFal


1. Check for stones or other obstructions in the Reservoir

2. If sand has been lost outside the reservoir you may need to add sand to the reservoir.

3. Verify that the pump is working properly and that there is nothing obstructing the inlet of the pump that would be reducing the flow, such as a dirty inlet sponge or obstruction.

4. Insure that your reservoir is level. If it is tilting towards the outflow due to a large rock placed on that edge for example, this may reduce the ability of the sand to flow into the sand exit properly.

5. There may be sand or other debris that is causing an obstruction. This is not common due to the grate over the bottom of the reservoir which prevents objects from entering the system that are large enough to obstruct it. See How to Clear an Obstruction below.




There is No Sand flowing thru the SandFall


1. Verify that the pump is working properly and that there is nothing obstructing the inlet of the pump that would be reducing the flow, such as a dirty inlet sponge or obstruction. 2. Stir the sand up a bit with tweezers or something similar. This can help get it flowing and may sometimes be needed to start the SandFall. 3. Verify there is enough sand in the reservoir. If you can see the holes of the grates clearly then there is probably not enough sand. 4. Verify there is not too much sand. Sometimes you can over fill the sand reservoir and the sand sticks enough to itself that the system cannot get started. This is uncommon, but If you think this might be the cause, try removing some sand and stirring what is left to start the fall. 5. Insure that your reservoir is level. If itis tilting towards the outflow due to a large rock placed on that edge fro example, this may reduce the ability of the sand to flow into the sand exit properly. 6. If nothing else has worked See How to Clear an Obstruction below.




My Water is Cloudy


Your filter should clear this up if given time. To speed the process you can either do water changes or use a water clarifier.




I have tried everything else, How do I Clear an Obstruction


This is generally not common, but it can happen. The most common obstruction is sand. When you turn the pump off the sand that is in the hose going up to the nozzle falls down and in rare instances can be too much to allow the pump to blow thru it when it is turned back on. This is more common the higher your sandfall is. There may also be some other debris, such as snails or gravel that are caught up in with the sand forming the clog. In order to clear the obstruction, first try to cover the grate in the bottom of the reservoir with your hand of another flat object. A piece of rubber works best. This will allow the full water pressue of the pump to try and clear any obstructions. Try turning the pump on and off a few times. If that did not work, then you will have to try and suction the material out. If the nozzle is removeable then that is the easiest access. Just place a smaller hose down the hose that leads to the nozzle to suction out any sand or debris in the hose. If the nozzle is firmly situated then try to suction the material from the grate acces sin the bottom of the reservor or from the pump access. You may also be able to use a pipe cleaner to break up the debris from either the grate access or the pump access.
