The CastleGuard Backwashing Carbon Filtration System provides point-of-entry carbon filtration for cleaner, fresher water throughout the home. Before water enters the main carbon tank, it passes through an included 4.5-inch by 20-inch sediment prefilter that helps capture dirt, sand, silt, rust, and other suspended particles. The prefiltered water then flows through the backwashing carbon media, which helps reduce chlorine-related tastes and odors when properly applied.
A backwashing control valve periodically reverses the water flow to flush trapped particles and redistribute the carbon bed. This automatic cleaning cycle helps maintain media contact, water flow, and long-term filtration performance. The system is available in 10, 15, and 20 GPM configurations to accommodate different household flow requirements.
Carbon filtration helps reduce chlorine-related tastes and odors, providing fresher water throughout the home.
Treat water at the point of entry so faucets, showers, appliances, and other fixtures receive filtered water.
The included sediment prefilter captures dirt, sand, rust, and other particles before they travel through your home’s water system.
The system automatically cleans and refreshes the carbon media to help maintain reliable filtration without constant attention.
Choose from 10, 15, or 20 GPM options to keep up with your household’s water needs—even when multiple showers, faucets, or appliances are running.
Enjoy filtered water for drinking, cooking, bathing, laundry, and water-using appliances without having to maintain filters at every faucet.
Water then flows into the appropriately sized backwashing carbon filtration tank for your home.
The system automatically backwashes by periodically reversing the flow through the control valve. This process flushes away trapped particles, redistributes the media bed, and helps maintain system performance. The activated carbon media reduces chlorine and chloramine, helping improve the taste and odor of the water while providing cleaner, better-quality water throughout the home.
Water then exits the backwashing carbon tank and enters the 4.5-inch-by-20-inch sediment filter housing.
A 5-micron sediment filter works like a physical screen for your water. As water passes through the cartridge, the filter media traps suspended particles that are about 5 microns or larger, such as dirt, sand, silt, rust, and other visible debris.
The treated and filtered water then circulates throughout the entire home, reaching every tap, shower, and appliance that utilizes water.

Provides point-of-entry treatment for residential water throughout the entire
home.
The automatic backwash cycle helps flush trapped particles and refresh the media bed.
An included 4.5-inch by 20-inch, 5-micron sediment filter helps protect the carbon tank
from dirt, sand, silt, rust, and particles.
Carbon media helps reduce chlorine-related tastes and odors when properly applied.
Choose 10, 15, or 20 GPM based on household water demand.
Includes the carbon tank, control valve, filtration media, sediment prefilter housing, cartridge,
O-ring, wrench, and installation components.
The CastleGuard Backwashing Carbon System helps reduce chlorine-related tastes and odors while also filtering sediment and suspended particles from the water entering your home. The result is fresher water for drinking, ice, cooking, and everyday use at faucets throughout the house.
The system’s automatic backwashing process helps keep the carbon media refreshed for consistent filtration over time. By reducing sediment and chlorine-related impurities before water reaches appliances, it supports cleaner water for laundry and helps protect water-using equipment throughout the home.
From a glass of water at dinner to a refreshing glass of iced tea shared with family and friends, cleaner water can make everyday life more enjoyable. By helping improve taste and odor, the backwashing carbon system supports a better water experience throughout the home.
Yes. During normal service, water flows through the carbon media. The control valve periodically initiates a
backwash cycle to flush trapped particles and refresh the media bed.
The system includes the backwashing carbon tank, model-sized mineral tank, backwashing control valve, carbon
media, 4.5-inch by 20-inch sediment housing, 5-micron sediment cartridge, housing O-ring, spanner wrench, and
installation components that may vary by configuration.
Replace the sediment cartridge every 3–6 months depending on incoming water quality and household usage.
No Bluetooth connectivity is listed in the supplied product data.
The SKU sheet identifies city water and applicable well-water treatment. A current water test is recommended for
well-water applications.
Choose based on required service flow: 10 GPM for smaller or lower-flow homes, 15 GPM for moderate demand,
and 20 GPM for larger or higher-flow applications.
A backwashing carbon system typically requires a drain for the cleaning cycle, but the exact drain requirements
were not provided in the SKU sheet and should be confirmed before publication.
The supplied SKU row does not provide a fixed interval. Media life varies based on water quality, chlorine level,
flow rate, and household usage.
No. A backwashing carbon filter improves taste and odor and addresses applicable chemical concerns, but it does
not remove hardness minerals. A separate water softener or conditioner is required for scale control.
That depends on the carbon media, water chemistry, contact time, and system configuration. Do not make a
specific contaminant-reduction claim without matching performance data for the exact media used in the
CastleGuard system.
A system must provide enough water during periods when several fixtures are operating at once. The 10, 15, and
20 GPM models allow the system to be matched more closely to household demand.
A properly sized and installed system is designed to support its listed service flow. Actual pressure and flow depend
on the home’s plumbing, incoming pressure, filter condition, and peak demand.
The system connects to the main water line and requires a drain for backwashing. Professional installation is
recommended unless the installer is experienced with whole-home water treatment and local plumbing
requirements.
Whole-home carbon filtration primarily treats taste, odor, chlorine-related concerns, and applicable chemicals
throughout the home. Reverse osmosis is normally installed at a drinking-water faucet and uses a membrane to
reduce dissolved solids and a wider range of drinking-water contaminants.
