Filter Replacement Schedules

Different filter types have different lifespans. Follow these recommended replacement intervals for optimal water quality and system performance.

Sediment Pre-Filter

6-12 months

Removes dirt, dust, and particles. Replace sooner if you notice visible discoloration or reduced water flow.

Carbon Filter

6-12 months

Eliminates chlorine, taste, and odor. Replace when chlorine taste or odor returns to the water.

RO Membrane

2-3 years

Core filtration component. Replace when water production slows or TDS levels increase significantly.

Alkaline/Mineral Cartridge

12-18 months

Enhances pH balance and mineral content. Replace when pH drops below 8.0 or water quality changes.

UV Lamp

Annually

Disinfects water through ultraviolet light. Replace every 365 days for 99.99% pathogen elimination, even if lamp still glows.

How to Replace Filters Yourself

Filter replacement is simple and takes just minutes. Follow these steps for your specific system type.

Before You Start

  • Turn off your water system or shut off the water valve
  • Gather your replacement filters and any tools needed (usually just a wrench)
  • Have paper towels or a bucket nearby to catch water drips
  • Consult your system manual to identify filter locations
  • Ensure you have the correct replacement filter for your model

General Replacement Process

  • Close the inlet valve to stop water flow into the system
  • Open the housing or cartridge to access the filter
  • Remove the old filter carefully - water may drip
  • Rinse the housing with clean water if needed
  • Insert the new filter, ensuring proper seating and direction
  • Close the housing securely - hand-tight is usually sufficient
  • Open the inlet valve slowly to restore water flow
  • Check all connections for leaks

System-Specific Tips

Whole Home Systems

Filters are typically mounted in vertical housings. Turn off the main water valve, relieve pressure by opening a faucet, then unscrew the housing from bottom to top. Replace filters and reverse the process.

Drinking Water Systems

Usually feature cartridge-style filters that twist out or slide out. Shut off the water to the system, then simply unscrew or slide out the old cartridge and insert the new one. Some systems require priming.

RO Systems

Contain multiple filter stages. Your system will have replacement instructions showing which pre-filters feed into the RO membrane. Replace pre-filters every 6-12 months and the RO membrane every 2-3 years.

UV Disinfection Systems

The UV lamp unscrews from its housing. Always wear gloves and avoid looking at the lamp when powered. Ensure the new lamp is rated for your system's wattage.

Important Reminders

  • Always use genuine pH Prescription replacement filters
  • Ensure the system is off before beginning
  • Check filter direction - most have arrows indicating flow
  • Save your filter replacement dates for warranty purposes

Troubleshooting Guide

Experiencing an issue? Here are solutions to common problems.

Reduced Water Flow or Pressure

Possible Causes: Clogged sediment filter, mineral buildup in lines, closed valve, or air in system.

Solutions:

  • Check if sediment filter is due for replacement (every 6-12 months)
  • Verify all valves are fully open
  • Run water for 5-10 minutes to purge air from system
  • Check for kinks or damage in tubing
  • If problem persists, call for professional service

Leaks from Connections

Possible Causes: Loose connections, worn O-rings, or over-tightened fittings.

Solutions:

  • Turn off water supply immediately
  • Try hand-tightening connections - do not over-tighten
  • Ensure filters are properly seated in housings
  • For persistent leaks, shut off system and call for service
  • Do not use the system if leaks continue

Unusual Taste or Odor in Water

Possible Causes: Expired carbon filter, new cartridge not fully activated, or contamination.

Solutions:

  • Check if carbon filter is due for replacement (6-12 months)
  • Run water for several minutes to flush new filters
  • Some new filters may have residual taste - this subsides
  • Ensure you're using the correct filter type for your system
  • If problem continues, contact us for water quality testing

Water Quality Has Changed

Possible Causes: Expired filters, source water changes, or system calibration drift.

Solutions:

  • Review filter replacement schedule - may be due for service
  • Verify alkaline and mineral cartridges haven't expired (12-18 months)
  • Check system settings and ensure proper calibration
  • Schedule a professional water quality test
  • We can help identify if filters or system adjustments are needed

System Won't Turn On

Possible Causes: Power issue, water valve closed, or system lock.

Solutions:

  • Check that system has power and outlet is working
  • Verify main water valve is fully open
  • Check for any visible damage to power cord
  • Consult system manual for reset procedures
  • If still unresponsive, contact our technical support

No Water Production from RO Tap

Possible Causes: Clogged pre-filter, failed RO membrane, or tank issue.

Solutions:

  • Check if pre-filters are due for replacement (6-12 months)
  • Verify RO membrane hasn't exceeded 2-3 year lifespan
  • Check storage tank pressure - should be 40-60 PSI
  • Run the system for a few minutes to flush lines
  • Call for professional diagnosis if issue persists

Can't Find the Right Filters

Possible Causes: Unsure about filter model, incorrect identification, or filters out of stock.

Solutions:

Maintenance Tips for Optimal Performance

Follow these best practices to keep your system running at peak performance and extend its lifespan.

Keep Filters on Schedule

Mark filter replacement dates on your calendar. Regular replacements prevent clogging, maintain water quality, and protect the system from damage.

Monitor Water Quality

Pay attention to taste, smell, and clarity. Changes can indicate filters need replacement sooner than expected due to high contaminant levels.

Check Connections Monthly

Look for leaks or loose connections. Catching small problems early prevents expensive damage and maintains system efficiency.

Use Genuine Filters

Always use pH Prescription replacement filters. Generic filters may not provide proper filtration and could damage your system.

Maintain Water Pressure

Keep water pressure between 40-80 PSI. High pressure can damage filters prematurely; low pressure may indicate clogging.

Store Filters Properly

Keep replacement filters in a cool, dry place before installation. Protect them from freezing and extreme heat for maximum effectiveness.

Document Replacements

Keep records of filter replacement dates. This documentation is important for warranty claims and warranty protection.

Professional Annual Inspection

Schedule a professional system check annually. Early detection of wear or issues prevents costly repairs down the road.

Schedule Professional Maintenance

Let our technicians handle your filter replacements. We come to you on a convenient schedule and ensure your system performs at its best.
