Tecreddy RV City Water Inlet with Brass Check Valve — White 3/4" GHT / 1/2" NPT, UV‑Resistant Durable Flange

This compact, weather-resistant inlet combines a 3/4" GHT internal thread with a 1/2" NPT external thread and a 3" flange diameter so it fits most RVs, campers and trailers. Its brass threaded pipe and plastic housing are engineered to resist corrosion, road salts, and UV exposure while the integrated check valve helps reduce backflow into your potable water system. Designed for straightforward swap-outs, the inlet uses an easy-grip knob for tool-free hose attachment and detachment.

How does this inlet connect to my RV water system?

The Tecreddy inlet uses standard thread sizes so it links directly to common garden hoses and RV supply plumbing. The 3/4" GHT internal thread accepts most city water hoses, while the 1/2" NPT external thread is compatible with typical RV supply fittings.

• 3/4" GHT internal thread for standard garden hoses
• 1/2" NPT external thread for RV plumbing compatibility
• 3" flange diameter for broad fitting coverage
• Easy-grip knob for quick hose attachment

What materials protect it from weather and wear?

Critical contact parts are solid brass to resist corrosion and maintain a tight seal, while the outer housing is a reinforced plastic built to withstand UV light and outdoor conditions. Those material choices extend service life and reduce maintenance compared with all-plastic or low-grade metal alternatives.

• Brass threaded pipe resists rust and ensures a secure connection
• Durable plastic housing withstands UV and road salt exposure
• Seals designed to limit leaks at the connection point
• White finish blends with RV exteriors and resists yellowing

How does the built-in check valve benefit my fresh-water system?

The integrated brass check valve allows water to enter the RV while preventing reverse flow that could contaminate your potable supply. It’s a passive safety feature that operates automatically with normal water pressure and hose use.

• One-way flow prevents back-siphoning into fresh-water lines
• Brass valve construction for reliable, long-term operation
• Simplifies hookups by combining inlet and valve in one unit
• Reduces need for separate external backflow devices

How easy is installation and routine use?

Replacement is straightforward: remove the old inlet, position the flange, and thread the new unit into place at the correct angle to maintain a watertight seal. The ergonomic knob means you can connect and disconnect hoses quickly without tools.

• Simple swap-out design for DIY installation
• Ergonomic knob for hand-tight hose attachment
• Fits common hole sizes used on most RVs and campers
• Requires minimal maintenance — inspect seals periodically

Who is this for: The Tecreddy RV City Water Inlet with Brass Check Valve is ideal for RV owners, camper renovators, and fleet operators who need a reliable, weather-resistant fresh-water fill solution. It suits anyone replacing a worn or damaged inlet or upgrading to a unit with an integrated check valve for easier hookups and improved backflow protection.
