SEAFLO Wall-Mount Water Inlet — White pressure-regulated freshwater fill with cap, anti-backflow

The SEAFLO Wall Mount Pressure Regulated Water Inlet (White) is a compact, surface-mounted freshwater fill and shore-water connection with built-in pressure regulation and a protective cap.

This inlet provides a tidy, secure connection point for shore power-style water hoses on boats, RVs, campers and tiny homes. Designed to mount to a wall or hull, it combines a standard threaded fill with an internal pressure regulator that helps prevent excessive incoming pressure from damaging onboard plumbing. Its white finish blends with most exteriors and the included cap helps keep debris and insects out when not in use.

How does this inlet protect my onboard plumbing?

The unit integrates a pressure-limiting mechanism that reduces high shore-water pressure to a safer level for typical freshwater systems. That decreases the risk of blown fittings, leaky faucets and strain on pumps. The construction also includes a check-valve action to reduce backflow risk.

• Built-in pressure regulator to lower incoming pressures
• Check-valve or anti-backflow design for system protection
• Durable housing resists corrosion and UV exposure
• Threaded cap prevents dirt and pests from entering

Is installation complicated and what hardware is needed?

Installation is straightforward for a basic wall-mount application and works with common plumbing fittings. You’ll cut or use an existing hole, secure the inlet with screws, and connect with standard hose or pipe fittings. No specialized tools are generally required, but proper sealing and a wrench for connections ensure a leak-free result.

• Mounts with standard screws (screw holes accessible from faceplate)
• Connects to common hose thread or pipe adapter fittings
• Recommended tools: drill, screwdriver, plumber’s tape and wrench
• Simple replacement for many OEM inlet openings

What materials and dimensions should I expect?

The inlet features a molded white plastic faceplate and body engineered for marine and outdoor use, providing corrosion resistance and a clean appearance. Internal regulator components are made to withstand repeated use and water exposure. The compact footprint fits in typical RV and vessel access locations without protruding excessively.

• White UV-resistant plastic face and housing
• Compact profile for wall- or hull-mounted installation
• Standard hose/pipe thread compatibility for easy hookup
• Protective screw-on cap included to keep inlet clean

How does this inlet fit into everyday use and maintenance?

The SEAFLO inlet is designed for daily convenience: quick hook-ups to shore water, straightforward winterizing and easy cleaning. Periodic inspection of the cap seal and regulator area keeps the unit functioning well for seasons. Replacement is simple if you upgrade or need service down the line.

• Quick connect/disconnect for shore water filling
• Cap seals protect against contaminants between uses
• Easy access for winterizing and flushing lines
• Low-maintenance—inspect seals and fittings annually

Who is this for: The SEAFLO Wall Mount Pressure Regulated Water Inlet (White) suits boat owners, RVers, vanlifers and tiny-house builders who need a neat exterior freshwater connection with pressure control. It’s especially helpful where shore-supplied water can arrive at higher pressures than onboard systems are rated for, and for anyone who wants a simple, durable inlet that integrates with common plumbing fittings and requires minimal upkeep.
