Pool equipment works hard. Pumps run for hours every day, filters handle everything that ends up in the water, and heaters and salt systems sit outside in sun and rain. When something stops working, the water can go from clear to cloudy quickly, so fast, accurate diagnosis matters.
Common equipment problems
- Pump will not start, hums or trips the breaker: often a failed capacitor, a seized motor bearing or an electrical problem.
- Pump runs but moves little water: clogged baskets or impeller, an air leak on the suction side, or a closed valve.
- Air in the pump basket: a loose lid, a worn O-ring or a leak in the suction line.
- High filter pressure: the filter is dirty or the grids or cartridge need replacement.
- Leaks at the equipment pad: worn seals, cracked fittings or a failing pump shaft seal.
- Heater will not fire: low water flow, a tripped safety switch, igniter problems or gas supply issues.
- Salt system errors: a scaled or worn cell, low salt reading or flow sensor problems.
Repair or replace?
Many problems are inexpensive fixes: a new capacitor, a lid O-ring, a shaft seal or a filter cartridge. Others raise a bigger question. An old single-speed pump that has failed is often worth replacing with a variable-speed pump, which uses far less electricity. A heater with a cracked heat exchanger may cost nearly as much to repair as to replace. A good technician will explain both options and the long-term costs.
Leaks
If the water level drops faster than normal evaporation, there may be a leak in the shell, the plumbing or the equipment. Some pool service providers do basic leak checks, and others refer the job to a leak detection specialist who can pressure test lines and locate leaks underground or underwater.
Questions worth asking
- What exactly failed, and what caused it?
- What does the repair cost compared with replacement?
- Is the replacement part covered by a warranty?
- Would a variable-speed pump save me money over time?
- Do you handle permits or electrical work if they are needed?
Safety
Pool equipment combines water and electricity, and heaters may run on gas. Leave electrical and gas work to qualified technicians, and turn equipment off at the breaker before opening anything yourself.
How long it takes
Simple repairs are often done in one visit. If a part has to be ordered, the provider may get the pool circulating temporarily or advise you on keeping the water safe until the repair is finished.
