{"@context":"https://schema.org","@type":"Product","name":"Grundig Brass RV City Water Fill Inlet with 3\" Flange & Check Valve - 3/4\" Female / 1/2\" Male Threaded, Fits Motorhome, Travel Trailer & Camper","description":"I. Product Overview A cracked, leaking, or stripped fill port turns every fill-up into a mess — water down the side of your rig, a soaked storage bay, and a fresh water tank that never quite fills. This 3\" brass city water fill inlet replaces it with a solid metal body that seals the same way the original did. It is the upgrade path for an RV that sees regular hookups — a part you install once and stop thinking about. II. Product Features Built-In Check Valve: Stops water from backflowing out of the inlet and keeps your fresh water system sealed. Solid Brass Body: A metal body that holds its shape and threads far longer than a plastic fitting. Corrosion-Resistant: Brass stands up to sun, rain, and temperature swings without rusting or pitting. Drop-In Threaded Fit: Threads into your existing plumbing the same way the original inlet did. III. Product Specifications Product Type: Brass RV City Water Fill Inlet with 3\" Flange and Check Valve Flange Diameter: 3 in Outer Connection: 3/4\" female threaded Inner Connection: 1/2\" male threaded Material: Brass Item Weight: 183 g (6.5 oz) Package Dimensions: 9.2 x 8 x 7 cm (3.6 x 3.1 x 2.8 in) IMPORTANT: This inlet is a connection point, not a pressure regulator. Use a pressure regulator between the campground spigot and your RV. IV. Package Includes 1 x Brass RV City Water Fill Inlet with 3\" Flange (check valve built in) 3 x Mounting Screw 1 x PE Tape 2 x Compressed Towel Sheets V. Precautions Don't Over-Tighten: Start the threads by hand to avoid cross-threading, and do not force the fitting — over-tightening can damage the inlet or the plumbing behind it. Winterize Before Freezing: Drain the inlet before the first freeze. Trapped water will expand and can split the body or the check valve. Keep the Cap On: Put the inlet cap back on whenever the hose is disconnected to keep dust, insects, and road debris out of the tank. Verify Fit Before Ordering: Measure your existing flange opening and mounting hole spacing before you buy.","descriptionSections":[{"heading":"I.
