Step One — Find Your Equipment Pad
Before you can understand your pool equipment, you have to find it. Pool equipment is rarely in a prominent location — builders tuck it out of sight for aesthetic reasons, which means new homeowners sometimes don't even know where it is until something goes wrong.
Where to Look
Pool equipment pads are almost always located close to the pool but out of the primary sightline. The most common locations for Sun Belt residential pools:
Once you find the pad, you'll see at minimum a pump and filter. Depending on your pool, you may also have a heater, automation panel, salt cell, UV system, and various valves and plumbing connections. Everything on that pad has a specific function in keeping your water clean, safe, and comfortable.
The Pump
Every Pool Has OneThe pump is the heart of your pool system. It draws water in from the pool through the skimmer and main drain, pushes it through the filter (and heater if installed), and returns it to the pool through the return jets. Without the pump running, nothing in the system works — filtration stops, chemistry becomes impossible to distribute, and algae establishes quickly.
Where the power comes from: Every pump is connected to a dedicated breaker — either on your home's main panel or a smaller secondary panel located near the equipment pad. If your pump stops running unexpectedly, a tripped breaker is always the first thing to check before assuming the pump itself has failed.

The Filter
Every Pool Has OneAfter the pump pulls water from the pool and pushes it through the plumbing, that water passes through the filter before returning to the pool. The filter's job is to physically remove debris — fine particles, dust, algae cells, hair, and anything else small enough to pass through the skimmer basket but large enough to be captured by the filter media.
Filters don't need their own power source. They do their job passively as long as water is flowing through them — which is why pump run time directly determines how much filtration your pool gets. More pump hours equals more filtration cycles. A filter that looks clean on the outside can still be failing if the pump isn't running long enough to turn the water over adequately.
There are three types of filter media used in residential pools, each with different maintenance requirements:
In Las Vegas, desert dust and hard water load filters faster than national manufacturer schedules account for. Filters should be cleaned or inspected when the pressure gauge reads 8–10 PSI above the clean baseline — regardless of the calendar. See our complete cartridge filter cleaning guide → and our professional filter cleaning service →
The Heater
Most Pools Have OnePool heaters sit downstream of the filter in the water flow path — water is cleaned first, then heated, then returned to the pool. In Las Vegas, heaters are primarily used to extend the swim season into fall and winter, and to heat attached spas to comfortable soaking temperatures. Most residential Las Vegas pools heat the spa regularly but only use the pool heater occasionally in the cooler months.
Heaters have a flow switch that shuts them down when water flow is insufficient — so a clogged filter or struggling pump will often cause the heater to stop working before anything else. If your heater isn't performing, check your filter pressure and pump operation first.
Heater longevity is directly tied to water chemistry — specifically calcium hardness and LSI balance. Low calcium corrodes the heat exchanger internally. High calcium scales it, reducing heat transfer. Both scenarios lead to premature heater failure — and heater damage caused by improper water chemistry is rarely covered under manufacturer warranty.
Pool Lights
Most Pools Have ThemThe majority of residential pools have at least one submerged light, and many newer Las Vegas pools have multiple smaller LED lights positioned throughout the pool and spa. Pool lights are typically LED in modern installations — they consume significantly less power than the old halogen lights and offer color-changing modes that older installations couldn't provide.
How they're controlled: Most pools have a dedicated light switch located near the home's back door or exterior wall closest to the pool — the same place you'd expect to find a patio light switch. Pools with automation systems can control the lights remotely through the automation panel or a smartphone app, including color, brightness, and timed schedules.
Pool light niches — the housing that holds the light in the pool wall — are also a potential leak location. If you notice the pool losing water only down to the level of the light and then holding steady, the light niche gasket may need replacement. See our pool leak detection guide →
Automation Systems
Specialty EquipmentAutomation panels are the control center for pools that have them — a single interface that manages every piece of equipment on the pad. Instead of walking to the equipment pad to adjust the heater, flip valves manually to switch from pool mode to spa mode, or check pump settings, an automation system handles all of it from a wall-mounted panel or a smartphone app.
Practical example: arriving home after work, you can switch the system to spa mode from your phone while still in traffic — the automation panel activates the valve actuators to redirect water flow to the spa, turns on the gas heater, and ramps the pump to spa speed. By the time you're changed and outside, the spa is ready. Without automation, you'd do each of those steps manually at the equipment pad.
Valve actuators are the motorized valves attached to the plumbing that automation systems control to redirect water between the pool, spa, water features, and cleaners. If you have actuators and they stop responding, check the automation panel and the power connection to each actuator before calling for service.
Major automation platforms we service and program include Pentair IntelliCenter, Hayward OmniLogic, and Jandy iAqualink. See our equipment service page → for full automation support.
Specialty Sanitation Equipment
Specialty EquipmentBeyond the standard pump, filter, and heater, many pools have supplemental sanitation systems that help produce chlorine automatically, improve water quality, or reduce the amount of chlorine needed for adequate sanitization. These aren't on every pool, but they're increasingly common — especially in Las Vegas where hard water and intense UV create a demanding sanitation environment.
