A safety note about filter tanks
Pool filter tanks hold water under pressure. Never loosen the clamp or lid while the pump is running, and always open the air relief valve before servicing. A tank that is cracked, bulging or has a damaged clamp should be taken out of service and checked by a pro before the pump runs again.
Know your filter type
Your filter type decides what can wear out and what a repair looks like. Check the label on the tank if you are not sure.
| Cartridge | Sand | DE (diatomaceous earth) | |
|---|---|---|---|
| How it filters | Pleated fabric elements | A bed of filter media | Grids coated with DE powder |
| How it is cleaned | Remove and hose off | Backwash | Backwash and recharge, plus periodic teardown |
| Parts that wear | Cartridges, end caps, tank o-ring | Media, laterals, multiport gasket | Grids, manifold, o-rings |
| Common failure | Torn or collapsed pleats | Broken lateral sends sand into pool | Torn grid sends DE into pool |
Signs you need a repair, not just a cleaning
- Sand or gray DE powder on the pool floor after the filter runs
- Pressure climbs soon after a thorough cleaning
- Water leaking from the tank body, clamp band or drain plug
- Cracks in the tank, lid or cartridge end caps
- Pleats that are torn, flattened or permanently stained
- Water stays cloudy even though chemistry is balanced
If the filter just needs cleaning, see pool filter cleaning.

What affects filter repair and replacement cost
- Part or whole filter. Elements and gaskets cost less than a new tank.
- Filter type and size. Larger filters and DE systems cost more to replace.
- Plumbing. A new filter with different connections may need replumbing.
- Brand. Pros commonly service Pentair, Hayward and Jandy filters.
- Disposal. Old sand and DE need proper disposal.
Before work begins, confirm that the pro you hire holds the Florida license your job requires.
Pool filter questions
How do I find pool filter replacement near me?
Send a request with your city, your filter type (cartridge, sand or DE) and what is wrong. Dominion Pool Pros passes it to an independent local pro who repairs and replaces pool filters in your area.
How much does pool filter replacement cost?
Replacing cartridge elements, sand or DE grids costs less than replacing a whole filter. A full replacement depends on the filter type and size, whether plumbing needs changing to fit the new unit, and the brand. Ask the pro to quote both the part and the full-filter option if your tank is older.
How do I know if my pool filter is failing?
Common signs are sand or DE blowing back into the pool, a tank that leaks at the clamp or drain, pressure that jumps quickly after cleaning, water that stays cloudy despite good chemistry, and visible cracks in the tank or cartridge end caps.
How often should pool filter cartridges or sand be replaced?
It depends on use, how often the filter is cleaned, water chemistry and debris load. Rather than a fixed schedule, replace cartridges when the pleats are torn, flattened or will not come clean, and sand when it clumps or channels. A pro can inspect it.
Should I switch filter types?
Sometimes. Each type has trade-offs in filtering, cleaning effort and water use. If you are replacing the whole filter anyway, ask the pro whether a different type suits your pool and your routine better.
