Filter pressure is higher than normal
Pool Filter Cleaning
A dirty filter can make every other pool problem worse.
When filter pressure climbs or water stays cloudy, chemicals alone will not fix the pool. Avalon Pools checks pressure, flow, debris load, and filter condition before recommending the next step.
Symptoms
What homeowners usually notice
Returns feel weak or water movement slows down
Pool stays cloudy after chemicals are added
Debris comes back after vacuuming
The heater shuts down because flow is poor
Common causes
- Cartridge, DE, or grid elements loaded with debris and oils
- Heavy leaves, dust, algae, or fine debris after storms or wind
- A filter that is undersized, aging, damaged, or overdue for service
- Valve or pump issues that mimic a filter problem
What Avalon checks
- Starting pressure, return flow, and equipment-pad layout
- Filter type, element condition, and signs of damage
- Whether cleaning is enough or parts need replacement
- How the filter condition affects heater, pump, and water clarity
Clean or replace parts?
- Cleaning is usually the first step when pressure is high and the filter is intact.
- Replacement parts may be needed when cartridges, grids, manifolds, or seals are damaged.
- If pressure rises again quickly, the pool may have an algae, debris, sizing, or circulation issue.

FAQ
Practical answers before the first visit
How often should a pool filter be cleaned?
It depends on pool size, filter type, debris load, and usage. Heavy debris, algae, or high pressure usually means the filter needs attention sooner.
Can a dirty filter affect my pool heater?
Yes. Poor water flow from a dirty filter can cause heater shutdowns or error codes, so filter pressure should be checked during heater troubleshooting.
