Pool Equipment Repair & Replacement in Brentwood, CA
Not sure which part failed? That's normal. The equipment pad is a chain: water flows from the pool through the pump, filter, heater, and sanitizer and back again. When one link fails, the symptoms often show up somewhere else.
Repairs & equipment, not weekly cleaning · No obligation
- 1Skimmer & main drain. Where water leaves the pool. A crack at the skimmer is one of the most common leaks.
- 2Pump. Pulls water from the pool and pushes it through everything else. If it stops, everything stops.
- 3Filter. DE, cartridge, or sand. Rising pressure or cloudy water points here.
- 4Pool heater or heat pump. Needs good water flow to fire. Many heater faults are really flow problems.
- 5Salt cell or chlorinator. Sanitizes the water on its way back. Salt cells scale up and wear out.
- 6Automation & valves. Timers, control panels, and valve actuators decide what runs and where water goes.
How the equipment pad works
Water leaves the pool through the skimmers and main drain, gets pulled through the pump, pushed through the filter, warmed by the heater if it's on, sanitized by a salt cell or chlorinator, and returned to the pool. Valves route water between pool and spa, and an automation system or timer controls when everything runs. The diagram below shows the order.
Match the symptom to the part
| Symptom | Most likely | Page |
|---|---|---|
| Nothing runs at the scheduled time | Timer, automation, breaker, or pump motor | Pump repair |
| Pump runs, water is cloudy | Filter, run time, or chemistry | Filter repair |
| Pool heater won't fire | Low flow, gas supply, igniter, or sensor | Pool heater repair |
| Water on the pad | Pump seal, filter O-ring, valve, or union | Leak detection |
| Light won't turn on | Breaker/GFCI, transformer, fixture | Light repair |
| Chlorine low with a salt system | Salt cell scaled or worn, or salt level | This page: salt cells |
| Spa won't fill or heat | Valve actuator position or automation setting | This page: valves & automation |
Valves, automation, and salt cells
- Valve actuators turn the pool/spa valves automatically. When one fails, the spa may not fill or the pool may drain into the spa.
- Automation controllers (control panels and apps) run the schedule. Faults can look like a dead pump or heater.
- Salt cells build scale and wear out over time; a worn cell stops producing enough chlorine.
- Plumbing and unions at the pad crack in the sun and leak at the joints.
What pool equipment repair usually costs
Costs depend on which component failed. Angi's national figures put pump repairs at about $100–$700 and pool heater repairs at about $160–$730, while replacing a pump averages about $1,300 (Angi, 2026). Automation, salt cells, and valves vary by brand and model.

Fix one part, or plan the whole pad?
When several components on the pad are the same age, one failure often follows another. It can make sense to replace the failed part now and plan the rest, or upgrade the pad in one visit if the pump, filter, and heater are all near the end of their life. The trade-offs are in repair or replace pool equipment. For pumps specifically, California's variable-speed rule shapes the choice.
Check any contractor, including one you find here
- Ask for the contractor's CSLB license number and look it up at cslb.ca.gov. Swimming pool contractors are generally licensed under the C-53 classification.
- Get the quote in writing, with the parts and the make and model of any new equipment.
- Don't pay large sums up front.
- For gas or electrical work on a pool heater or light, make sure the person doing it is qualified for that work.

Pool Equipment Repair: common questions
What is a pool equipment pad?
The spot, usually beside the house or at the back of the yard, where the pump, filter, heater, sanitizer, valves, and controls sit. All of the pool's water passes through it.
Should I replace all my pool equipment at once?
Not necessarily. Replacing only what failed is often right. If several parts are the same age and showing wear, a planned pad upgrade can avoid repeat service calls.
Why does my spa not heat or fill?
Often a valve actuator or automation setting isn't routing water to the spa, or the heater isn't getting enough flow. It's usually diagnosable at the pad.
