Pool Equipment Repair
Everything on the equipment pad is connected, so a symptom in one component often originates in another. This is the overview: what each part does, how long it lasts, and what goes wrong with it.
The pad, component by component
| Component | Service life | Common failures | Typical repair |
|---|---|---|---|
| Pump | 8–12 years | Bearings, seal, capacitor, impeller | $150–$600 |
| Filter | 10–15 years (housing) | Media exhausted, cracked housing, failed laterals | $150–$900 |
| Heater | 10–15 years | Igniter, sensors, control board, heat exchanger | $200–$1,200 |
| Salt cell | 3–7 years | Output decline, scale, plate wear | $400–$1,200 (replace) |
| Automation / control | 10–15 years | Relays, control board, actuators | $200–$900 |
| Valves and actuators | 8–15 years | Seized diverter, failed actuator motor | $150–$600 |
| Timer | 10–20 years | Mechanism failure, lost schedule | $100–$400 |
| Chlorinator | 5–10 years | Cracked housing, failed check valve | $150–$500 |
Symptoms often start somewhere else
The equipment pad is one hydraulic system, so a fault in one component regularly presents as a symptom in another. Chasing the symptom rather than the cause is how people end up replacing healthy equipment.
- A heater that will not fire. Very often a dirty filter or a failing pump. The heater is refusing to run because water flow is inadequate — it is protecting itself, not failing.
- A pump that will not prime. Frequently a suction-side air leak at a valve, union or lid o-ring rather than a pump fault.
- Cloudy water. Usually filtration, which may mean exhausted media, a cracked lateral, or a pump not running long enough.
- A salt cell reporting low output. Sometimes scale on the plates rather than a failed cell — worth cleaning before replacing.
- High filter pressure. The filter needs cleaning or the media is exhausted. It also strains the pump, so leaving it costs more than the filter service.
When the pool is drained anyway
If a remodel is on the horizon, the equipment conversation changes. The pad is accessible, the plumbing is exposed and the pool is already out of service — which is the cheapest possible moment to deal with anything on this list.
- Ageing pump. Especially a single-speed one. Replace during the remodel and avoid a second mobilization.
- Heater past ten years. Cheaper to swap while the pad is open than after new decking is poured.
- Lighting. Changing fixtures in an empty pool avoids a diver or a second drain entirely.
- Automation and salt systems. Both involve pad plumbing and electrical work best done before the deck is finished.
- Valves and plumbing. Deteriorated PVC and seized valves are easy to address while everything is drained.
Safety boundaries
What makes equipment last
- Water chemistry. The dominant factor for heaters and salt cells. Low pH corrodes; high calcium scales. Both are invisible until they are expensive.
- Clean filtration. A dirty filter makes the pump work harder and starves the heater of flow. The cheapest maintenance there is.
- Correct sizing. Oversized pumps stress plumbing; undersized heaters run constantly. Both fail early.
- Shade and ventilation. Equipment cooked in direct sun degrades faster, and pumps need airflow to shed motor heat.
- Off-season attention. Rodents and insects nesting in idle equipment cause a surprising share of spring failures.
What this project needs measured
Measurements are only requested when they change the price of the work you selected. Everything below is collected inside the estimator — you can enter dimensions you already know or measure as you go.
Required
No measurement required
This project is diagnosed from symptoms and equipment details rather than dimensions.
What the estimator will ask you
- Which component seems to be failing
- What you are seeing, hearing or reading on a display
- Brands and models from the data plates
- Approximate age of the equipment
- Photos of the whole equipment pad
- Whether the pool is currently usable
- Whether you would consider upgrades while work is being done
How to read a PoolSavr estimate
- Step 1
Instant estimate
Based on your project selections and general pricing assumptions. Useful for deciding whether a project is realistic.
- Step 2
Measured estimate
Uses your pool, spa, or deck dimensions to price the work against the areas actually being resurfaced, tiled, or replaced.
- Step 3

Prepared by a licensed professional after inspecting the site. This is the only number that becomes a contract.
PoolSavr is an estimating and matching platform. We do not perform pool work ourselves — licensed local professionals do. Contractors pay PoolSavr for qualified project leads, which is how the estimating tools stay free for homeowners.

Frequently asked questions
- How long does pool equipment last?
- Pumps 8–12 years, filters 10–15 for the housing, heaters 10–15, salt cells 3–7, and automation 10–15. Water chemistry and run time are the variables that move those numbers most.
- Why does my heater stop when my pump seems fine?
- Because heaters refuse to fire without adequate water flow, and flow can be restricted by a dirty filter or a pump that is running but underperforming. Check the filter pressure before assuming the heater is at fault — it may be protecting itself correctly.
- Should I replace all my equipment at once?
- Not usually, unless it is all of a similar age and you are remodeling anyway. Components have different service lives, and replacing a healthy filter alongside a failed pump is money spent early for no benefit. The exception is during a remodel, when access is free.
- What is the cheapest thing I can do to make equipment last?
- Keep the filter clean and the water balanced. A dirty filter makes the pump work harder and starves the heater of flow, and imbalanced water quietly destroys heat exchangers and salt cells. Neither costs anything but attention.
- Can I upgrade equipment during a pool remodel?
- It is the cheapest time to do it. The pool is drained, the pad is accessible and the plumbing is exposed, so you avoid a second mobilization — and lighting in particular is far cheaper to change in an empty pool.
