Aqualisa aquaforce 30 pump
Try unplugging your pump and disconnecting the union fitting found at the top of the check valve. Reset the breaker if it has tripped and check the line with a hair dryer to make sure it is working. GFCIs are very sensitive and can sometimes trip during a thunderstorm or a power surge. Make sure the safety breaker on the ground fault circuit interrupter has not tripped. You may even be able to accomplish this without disconnecting the fitting on the end of the check valve. A vapor lock can be fixed by tilting the pump to allow the air to escape from the intake. Listen to see if you hear the hum of the pump. In this situation the impeller is basically spinning, but water is not being pushed. The pumps are designed to push water, not air…so an air bubble gets trapped and the pump becomes vapor locked. This happens sometimes when the electric goes off and shuts down the pump. It simply means that air is trapped in the volute of the pump. Is the pump not working at all but you hear a hum? Click here to purchase a new aquascape pump checkvalve to replace the broken checkvalve. You can replace the checkvalve, just be sure to pick out the appropriate valve for your aquascape pump. Click on Checkvalves and look at the check valve pictures. Checkvalves are sized by the type/brand of skimmer you have. There is a flapper inside the check valve and if the check valve rattles when shaken, then it probably is broken and this will affect the flow of water and also if the biofalls empties out when the pump is shut down, that also indicates a broken checkvalve. Slow flow to the waterfalls could mean that the aquascape pump is still running but you may have a broken check valve. The net and mat can be cleaned often to assist the pump’s efficiency. Check for a clogged skimmer net or clogged skimmer filter mat. Check for debris in the box or rocks blocking the entrance to the skimmer. Make sure nothing is blocking the flow of water to the pump. Your pump will not work if the skimmer box runs dry, this may even make the pump inoperable. Check your water level and make sure the skimmer has water in it.
