Electrical Problems With Swimming Pools You Can Easily Fix

by Editor on June 1, 2013


Even the most careful swimming pool owner may have to contend with electrical problems occasionally. Failure to quickly locate and repair the problem could be costly and also cause unnecessary health hazards. Let’s quickly take a look at some basic electrical problems pool owners face and offer up some solutions. In many cases, you may have to bite the bullet and call in a professional to make the repairs for the sake of your pool.

The Heating System

When your heater malfunctions, the issue may have little to do with the pump or filter. You’ll need to determine where the problem is arising, before even attempting to repair it. If the heater does not stay on or it refuses to switch on at all, begin by cleaning the filter, turning up the thermostat, and trying the heater again, since a dirty filter can cause low pressure. Check the shut-off valve on the gas heaters to make sure the value is supplying the heater with fuel.

If you have an electrical unit, check to ensure the connections are tight and that the terminals are not affected by corrosion. If this doesn’t solve the issue, attach a voltmeter to a transformer’s terminal for a reading. The transformer is fine if it reads 20-28 volts; lower than this means there is an issue with the voltage supply.

In-ground Swimming Pool Light Replacement

There will come a time when you have to change the in-ground swimming pool light. While this can be awkward, you don’t necessarily need to drain the water or hire a professional. It is entirely possible to remove the light, without having to disconnect wiring. It may involve taking a dip, but you can safely remove an in-ground light by following the tips below.

Switch off the pool light’s circuit breaker and place a non-contact voltage tester beside the wall switch of the pool light. You will be alerted to the presence of electricity as the tester beeps and shines. Switch it ‘On’ to check the switch for electricity before switching off.

If you can’t reach the pool light housing bezel’s screw from outside the pool, you will need to enter the water to remove the screw. From the side of the pool, pull the pool light housing and utilize the waterproof cord to replace the light before leaving the housing on a towel beside you. Loosen the bezel’s screws and remove it along with the lens and gasket. If there are corroded screws, replace them and check the gasket for cracks, repairing or replacing it if necessary.

Use a towel to dry the inside of the housing, remove the bulb, and replace with an identical bulb. Reversing the entire process should lead to a successful returning of the pool light, but if air bubbles are apparent from the housing once it has been returned to the water, you will need to remove and replace everything to ensure the light is sealed. After everything is back in place, simply turn the circuit breaker back on.

The above are relatively basic electrical problems with swimming pools and if you encounter something more advanced, it may be time to call in the experts.
