Frequently Asked Questions:
How do you install the Pentek RFC20-BB?
- Turn off water supply. Press red pressure-relief button (if present).
- Unscrew housing. Remove large o-ring, wipe clean and set aside.
- Discard used filter cartridge. Wash housing with dish soap and warm water using a nonabrasive sponge or cloth. Rinse thoroughly.
- Fill 1/3 with water. Add about 1 tablespoon of bleach and scrub to disinfect. Rinse thoroughly.
- Lubricate o-ring with clean silicone grease. Change o-ring if any damage cuts or degradation are present. Insert o-ring in groove.
- NOTE: This step is important to ensure a proper housing seal. Make certain the o-ring is seated level in the groove.
- Insert new filter cartridge.
- Screw housing onto the cap and hand-tighten. Do not over tighten. Make sure cap standpipe slips into cartridge.
- Turn on water supply. Press pressure-relief button (if present). Check for leaks before leaving installation.Most fit issues result from either an old cartridge o-ring that fell off when removing the old cartridge, or failing to get the standpipe lined up when hand tightening the housing.
How often should you replace the Pentek RFC20-BB?
Changing your Pentek RFC20-BB is a very quick and easy process that should be done once every six months.
What contaminants does the Pentek RFC20-BB reduce?
The Pentek RFC20-BB reduces the following contaminants:
- Sediment
- Bad Taste & Odor
Is the Pentek RFC20-BB suitable for well water?
The Pentek RFC20-BB can be used on well water to reduce sediment and improve taste and odor, but it is not intended to remove bacteria, viruses, or dissolved contaminants such as iron or manganese. If your well water contains these contaminants, additional treatment equipment may be necessary.
What makes the Pentek RFC20-BB different from a standard carbon block filter?
The RFC20-BB uses a radial flow granular activated carbon (GAC) design that allows water to flow through the filter with less pressure drop while significantly reducing the carbon fines that are often associated with conventional GAC filters. It is especially well-suited for whole-house systems that require higher flow rates.
