Filter Cartridge Replacement in O Fallon, MO

Filter Cartridge Replacement in O Fallon, MO

Cartridge filters only work while the cartridge has capacity left. Once it loads up, you get pressure loss, or worse, a carbon cartridge that stops removing chlorine without any visible sign. O Fallon, MO Whole House Water Filtration handles filter cartridge replacement for homes across O Fallon, MO.

On a typical service visit we:

• Close the inlet and outlet valves and open the bypass
• Relieve pressure with the red button on the housing cap
• Pull the old cartridge and clean the sump
• Inspect and lube the O-ring with food-grade silicone
• Install the new cartridge and check for drips

That O-ring step matters. A dry or twisted O-ring is the most common cause of a slow leak at the housing threads after a cartridge change.

We stock common sizes such as 2.5 x 10, 4.5 x 10 and 4.5 x 20 inch, in pleated, spun, carbon block and specialty media. If your housing is cracked or yellowed with age, we will point that out before it splits.

Most whole house sediment cartridges need changing every 3 to 6 months, and carbon blocks every 6 to 12, but your water decides the real number.
