All pool equipment must be properly disconnected from your electrical panel. If your pool has a gas heater it will also need to be disconnected. Both gas and electrical must be inspected for proper disconnection.
Before swimming pool demolition begins, all electrical circuits relating to the pool and spa must be appropriately de-energized. You cannot just simply turn off the switch. All cities and counties have requirements for electrical disconnects associated with a swimming pool demolition. Generally, they want the electrical conduits disconnected from the electrical panel or subpanel and capped.
The first challenge is finding where the power is coming from. If it’s the main service panel, that’s easy. On the other hand, it may be coming from a subpanel, especially in some older homes where multiple layers of electrical work have been done. We have found subpanels under houses and in closets, attics, and even kitchen cabinets!
If your swimming pool is equipped with a heater, the heater must be disconnected, the gas shut off, and the line capped. If your heater is less than three years old, it may have some value. If it’s older than that it is probably obsolete.
Gas lines on newer swimming pools are installed with shutoff valves at the meter. In that case, the gas line can be shut off without shutting off the gas supply to the entire house. If no shutoff valve was installed (true of older pools), the gas for the house must be shut off to disconnect the gas line. Keep in mind that when the main gas line to your home is shut off, the pilot lights in any gas appliances go off as well. These pilot lights must be relit as soon as the gas is turned back on. Your contractor should do this as part of its service.
Newer gas meters are equipped with an earthquake shutoff valve. When the gas is shut off to terminate the heater line, this valve will automatically close due to the pressure drop. Only the service provider (PG&E) can reset the valve. To avoid the inconvenience of going without utilities, your contractor must coordinate the shutoff with your provider.
We are often asked about leaving gas lines for later use for barbeques, fire pits, and the like. This is not a particularly good idea. Most heater lines we find are steel and have been in the ground for many years. As a result, the line can become corroded. Moreover, many heater lines are not buried and lie directly under the pool deck. Demolition often damages the gas line.
