FlowPur/ Watts RV 10-inch Exterior GAC Replacement Water Filter Cartridge with Spanner & Hose Fittings

This replacement kit supplies a fresh Granular Activated Carbon (GAC) cartridge and the tools needed to service an exterior RV water inlet quickly and reliably. The WCBCS-975RV cartridge is sized for common 10" filter housings used on many name-brand exterior or total water-supply systems and includes a spanner wrench and garden-hose fittings so you can swap the cartridge without special plumbing parts. It’s engineered to reduce taste and odor issues associated with temporary or variable campground water while matching common housing dimensions for easy compatibility.

How simple is installation for an RV owner?

Installation is intended for straightforward, tool-minimal replacement. The kit includes a spanner wrench to remove the housing sump and garden-hose fittings to reconnect to the external water supply, so most swaps are doable at a campsite or at home in minutes.

• Comes with a spanner wrench for safe, controlled sump removal
• Includes garden-hose fittings to match RV exterior water connections
• Fits standard 10" housings — no special adapters in most cases
• Designed for hand-tightening after cartridge insertion

What does the Granular Activated Carbon (GAC) cartridge actually do?

The GAC #8 cartridge reduces common aesthetic concerns in freshwater sources, such as chlorine taste and odor, by adsorbing certain chemicals and particles. It’s suitable as a point-of-entry cartridge for exterior supply lines that feed onboard plumbing, improving taste and smell of potable water used in sinks, showers and faucets.

• GAC media targets chlorine and many organic compounds that affect taste and odor
• Helps improve water clarity and overall drinking-water experience
• Intended for freshwater supply lines; not a disinfectant or microbe sterilizer
• Compatible with common RV plumbing fixtures when used in the exterior housing

Will this filter fit my existing system and how often should I replace it?

The cartridge is built to fit most manufacturers’ 10" filter housings; confirm internal diameter and housing thread type when in doubt. Replacement frequency depends on water quality and usage, but routine swaps every 3–6 months are common for regular RV travelers.

• Designed for 10" housings used by many name-brand exterior systems
• Check your housing size and threads before purchasing to ensure fit
• Replace more often in heavy-use or poor-quality water conditions
• Carry a spare cartridge for long trips to campsites with uncertain water sources

What’s included in the kit and what should I expect during service?

The WCBCS-975RV package contains the GAC #8 replacement cartridge plus the accessories needed to remove housings and reconnect to garden-hose type supply lines. Expect a quick service session: depressurize the line, use the spanner wrench to open the housing, swap the cartridge, reseal and test for leaks.

• One Granular Activated Carbon replacement cartridge (#8)
• Spanner wrench for housing sump removal
• Garden-hose fittings to simplify exterior connections
• Fits most 10" housings — check compatibility with your brand/model

Who is this for: RV and camper owners who use external water hookups and want an easy-to-install replacement filter that improves taste and odor for onboard freshwater systems. It’s ideal for seasonal travelers, weekend campers and anyone who prefers a simple cartridge swap with compatible 10" housings and basic hand tools included.
