We often get water bore repair calls where the problem turns out to be the start capacitor. Call on 9246 0111. 

In a single phase submersible bore pump the start capacitor is ordinarily in the 240 volt start box. Three phase submersible pumps do not have start capacitors. In some centrifugal pumps the capacitor can be mounted externally on the pump motor housing. It is surprising how often a faulty capacitor is missed as the cause of a bore pump problem particularly when tests are carried out by someone who is not specifically experienced in bore pump service work. Even trained general electricians can misdiagnose this simple problem.

Often a capacitor problem can spotted visually as it will commonly swell or rupture. A start capacitor should be perfectly cylindrical. Sometimes though a faulty capacitor can only be diagnosed by the serviceman actually testing it when disconnected. As the start box is mains powered it does need a licensed electrician or certified electrical worker to test and replace the start capacitor. Our specialist bore electrician Dave is expert at this. 

One of our clients from Baldivis sent us these pics of inside his submersible water bore start box.

This is a single phase start box and is a particularly dramatic example of a blown start capacitor.
