| Whistling | Valve issue | Replace or adjust valve |
Low Water Pressure Fixes
Low water pressure can be a sign of trouble with your Rheem Marathon Water Heater. The following troubleshooting tips will help restore the proper water flow. Each fix is crucial for a fully functioning system.
Inspecting For Clogs
Clogs can seriously hinder water pressure. Start by checking faucets and showerheads. Look for mineral deposits that block water flow. Use a vinegar solution to dissolve these build-ups.
- Remove aerators and rinse them thoroughly.
- Soak parts in vinegar for a few hours.
- Use a small brush to remove leftover deposits.
Check the pipes for any visible clogs or obstructions. If pipes are old or corroded, consider consulting a professional.
Pressure Relief Valve Assessment
The pressure relief valve ensures safe operation. A faulty valve affects water pressure. To check the valve:
- Turn off the heater and water supply.
- Place a bucket under the valve.
- Lift the valve’s lever carefully.
