Before you start fixing your submersible pump repair Auckland, it is important to remember that they are quiet pumps and have a low profile. It is easy to configure these pumps for horizontal or vertical use or any angle between. Submersible water pump that use electricity are workhorses that do well for storm-water drainage and flood control. And if something goes wrong, the configuration of these pumps makes it easy to fix and maintain them. This troubleshooting guide will help you see if there is a quick fix for what is ailing your pump.
The motor doesn’t start
This is the obvious problem with Submersible water pump. You should check your pump for a tripped cutout or blown fuses. If the issue is intermittent, it could be corroded or dirty cutout receptacles. You should then check the power voltage at the contact point for the pressure switch. Corrosion, rust or debris can cause irregular voltage. Motors that use electricity do not like that. You should look to see if there is anything bounding the submersible pump. Debris or sand could be the culprit. You will get amp readings up to 6 times higher than normal before safety overload trips.
The motor runs too often or continuously
A system leak will cause both of the above issues. You should replace any damaged or leaking pipes and check the level of water to ensure that your pump has not exceeded the well capacity. Faulty pressure switches will cause the motor to cycle too fast or stay on. You should clean the contacts and double-check the settings before you do submersible pump repairs.
A motor that doesn’t shut off can indicate that the screen of your pump is blocked or that the check valve is stuck. Make sure you inspect both.
A tripping overload protector
You should check if you have any overload protectors exposed to direct sunlight. That is enough heat to cause them to trip. Ventilate or shade the box. If you are using temporary power or you are on a construction site, your submersible pump might be drawing incorrect voltage. You need to check the line terminals to determine if this is the main source of the problem.
Less water running through the pump system
You should start by checking the valve to see if it has failed or has been installed incorrectly. If neither of these is the cause then your pump may be air bound. Or maybe it is bound by something that has been caught in the impeller. You can have a sight inspection to determine the cause. Proper placement will be necessary for optimum operation. Insufficient flow of water might show that your pump is not fully submerged.
Excessive noise
You can easily do a submersible pump repair Auckland for excessive noise by checking all the valves in the line to the submersible pump. If something has changed the flow, it will drop the head pressure. Cavitation is the cause of most pump noise. Check the alignment between the pump and the driver.
