New pond pumps are very energy-efficient and reliable than ever before. As with other machines, though, things can and do go wrong. Most of these problems are rather predictable, and a few simple checks can resolve most pump failures. Before contacting the pump manufacturer, users can learn about this here.
Check the Water Flow
This is one of the most common pond pump problems users encounter. The pump simply can’t move water if there’s no access. First, find out whether there’s anything blocking water from the pump, such as a clogged skimmer opening or a piece of debris. Second, see if the pond’s water level is low, which may keep the pump from moving enough water through its skimmer box.
Look for Vapor Lock
Next, users should check for vapor lock. A pump may become vapor locked when there’s an air bubble in the volute, or primary internal space. The impeller will work as intended, but because of the air bubble, it will not move water. Here, the solution is relatively simple; tilt the entire pump so the intake faces upward and the air bubble can escape.
Check for Current
It’s important to ensure the pump is getting electricity. Check the circuit breaker and ground fault to see whether either has been tripped. It may help to plug a different machine into the pump outlet to make sure there’s power going to it. If not, call an electrician.
Inspect the Pump
Check the pump intake for debris that may have become stuck. Most pond pumps handle small debris very well, but a rock or a large piece of organic matter may become lodged in the intake or the impeller.
After the pump has been removed and cleaned, check to see if the impeller spins. If it works as normal, re-install the pump and try again. However, if the impeller spins and there’s no water flow, check again to see if the plumbing has been cleared and the pump is getting sufficient water.
These basic troubleshooting tips will resolve most pump issues. If a user goes down the list and nothing works, though, it’s time to call the pump manufacturer.
