Pool Filter Repair
Your pool filter keeps dirt, oils, and bacteria out of the water. When it fails, water turns cloudy and equipment takes stress.
WaterTex Pools provides pool filter repair across Dallas–Fort Worth.
We repair cartridge, sand, and DE filters.
If your filter is leaking, building pressure, or not cleaning the water, it needs service.
Signs Your Pool Filter Needs Repair
Ignoring them leads to algae, plumbing strain, and pump damage.
Common warning signs include:
Cloudy or green water: If chemistry is balanced but water stays dull, filtration is failing.
High or low pressure readings: Pressure that spikes or drops outside normal range points to internal issues.
Debris returning to the pool: Dirt blowing back through returns means the filter is bypassing media.
Unusual noises: Grinding or rattling often means broken internals or valve failure.
Leaks at the filter tank or valves: Water near the filter should never be ignored.
Pool Filter Types We Repair
Each filter type fails in different ways. Correct repair depends on knowing the system.
Cartridge Filter Repair
- Torn or collapsed cartridges
- Cracked end caps
- Housing or band clamp damage
- Worn O-rings and air leaks
Some cartridges can be replaced. Housing damage must be addressed immediately.
Sand Filter Repair
- Broken laterals
- Channeling inside the sand bed
- Multiport valve failure
- Sand media replacement
Sand filters often fail slowly, then suddenly.
DE Filter Repair
- Ripped grids
- Cracked manifolds
- Backwash valve leaks
- DE powder returning to the pool
DE filters require full disassembly to repair correctly.
Common Pool Filter Repairs
Many filter issues repeat across systems.
We regularly repair:
- Multiport valves
- Pressure gauges
- Band clamps
- Tank seals and gaskets
- Internal grids or cartridges
If parts are no longer safe or available, replacement is discussed before work begins.
Our Pool Filter Repair Process
We focus on fixing the cause, not the symptom.
Step 1: System check
We review pressure, flow, and visible leaks.
Step 2: Disassembly
The filter is opened and internal components are inspected.
Step 3: Repair or part replacement
Only failed components are replaced.
Step 4: Reassembly and testing
Pressure and flow are verified before the system is restarted.
You are shown what failed and why.
Preventing Repeat Filter Failures
Some failures are avoidable. Basic care helps reduce breakdowns:
- Clean cartridges every 4–6 months when in use
- Backwash sand and DE filters as needed
- Check O-rings and seals during cleanings
- Address pressure changes early
An annual inspection helps catch wear before damage spreads.
When Filter Replacement Makes More Sense
Repair is not always the right call. Replacement should be considered if:
- The filter is over 7–10 years old
- Tank cracks are present
- Repairs are becoming frequent
- The filter is undersized for the pool
We explain repair cost versus replacement cost clearly.
Why Pool Filter Repairs Should Be Handled by a Professional
Pool filters operate under pressure. Improper repairs can cause tank failure or injury.
A qualified technician:
- Knows safe pressure limits
- Uses correct parts for the filter model
- Prevents leaks that damage pads and plumbing
If a filter is leaking or bulging, it should not be run.
