Shurflo Water Inlets & Pressure Regulators
Shurflo's city water inlets and pressure regulators are engineered specifically for recreational vehicles (RVs) and marine applications, providing critical protection against the fluctuating pressures and potential damage that municipal water connections can inflict on onboard plumbing systems. When you connect to campground hookups or dock water supplies, you're often dealing with unpredictable pressure levels that can range from weak trickles to damaging surges. That's where Shurflo's specialized approach to water inlets and pressure regulators becomes essential.
Exclusive Diaphragm Design Technology
What distinguishes Shurflo in this product category is their exclusive diaphragm design, which safeguards against the potential hazards of high-pressure damage commonly associated with city water systems. Unlike traditional pressure regulator designs that can wear out quickly or fail to respond to sudden pressure spikes, this diaphragm design prevents high-pressure damage and limits water pressure while including a check valve. This integrated approach means you're getting multiple layers of protection in a single, compact unit.
The 183 Series Water Entry Systems
Shurflo's 183 series represents their most popular line of combination water inlets with integrated pressure regulation. The regulator automatically limits incoming water pressure to a safe level of 65 PSI, optimal for RV and marine plumbing systems. This precise pressure control prevents common issues associated with high water pressure, such as leaking pipes, dripping faucets, and the premature failure of water system components. Available in chrome, black, and white finishes, these wall-mount units feature a standard 3/4" GHT Female Swivel Inlet and a 1/2" MPT Outlet, ensuring compatibility with virtually any RV or marine water system configuration.
Built-In Safety Features
Beyond pressure regulation, Shurflo's water inlets incorporate comprehensive safety mechanisms. Central to the design is the inclusion of a backflow preventer, which ensures that once water enters your system, it cannot reverse direction and potentially contaminate the supply source. The filter screen helps prevent dirt and foreign substance build-up, while the built-in check valve prevents water loss when the pump is in use. These features work together to maintain water quality and system integrity, particularly important during extended trips when you're connecting to unfamiliar water sources.
Multiple Pressure Options
While the 65 PSI model is most common for RV and marine use, Shurflo offers available working pressures of 30, 50 & 65 PSI [2.1 - 4.5 bar] to accommodate different system requirements. This flexibility makes Shurflo products suitable for everything from compact camper vans to large motorhomes and sailboats, where plumbing system specifications may vary significantly. The pressure reducer valves are designed as fixed-pressure, non-adjustable devices, which eliminates the risk of incorrect settings and ensures consistent, reliable performance throughout the life of the product.
Installation and Durability
Shurflo designs these units for straightforward installation with quick, permanent wall mounting that works with walls of any thickness. The leak-tight, stress- and crack-resistant construction ensures long-term reliability even in the demanding environments of mobile applications, where vibration, temperature fluctuations, and regular movement can challenge inferior components. Whether you're outfitting a new RV build or replacing aging water entry equipment, Shurflo's water inlets and pressure regulators deliver the protection and performance that serious RV and boating enthusiasts depend on.
