<h3>Shurflo: Trusted Water Pump Solutions for Marine and RV Applications</h3> <p>Shurflo, now part of the Pentair family, has built a reputation as one of the most trusted names in water pump technology for marine, recreational vehicle, and industrial applications. For decades, professionals and enthusiasts alike have relied on Shurflo's engineering expertise to deliver consistent, reliable fluid movement in demanding environments. From weekend boaters to full-time RVers, Shurflo pumps provide the dependable performance needed when you're away from shore power and municipal water connections.</p> <p>What sets Shurflo apart is the brand's commitment to efficient design and durable construction. Their pumps utilize demand-initiated automatic operation, which means the pump activates when you open a faucet and shuts off when you close it—conserving battery power and reducing wear. The multi-chamber diaphragm design minimizes pulsation, delivering smooth water flow without the hammering or surging common in lesser pumps. This attention to detail has made Shurflo the go-to choice for boat builders, RV manufacturers, and aftermarket upgraders who demand quality.</p> <h3>Marine Pumping Solutions</h3> <p>On the water, Shurflo products keep boats clean and fish healthy. The brand's <a href="/7568-shurflo-wash-down-pumps-systems-201156">wash down pumps and systems</a> deliver the high-pressure spray needed to rinse decks, clean fish, and remove salt residue after a day on the ocean. These compact, self-priming pumps can run dry without damage and handle the corrosive marine environment with ease. For anglers, <a href="/7568-shurflo-livewell-aerator-pumps-200624">livewell and aerator pumps</a> ensure baitfish and tournament catches stay lively by maintaining proper water circulation and oxygenation in livewells and baitwells.</p> <h3>RV and Mobile Water Systems</h3> <p>In recreational vehicles and mobile applications, fresh water delivery is essential for comfort and convenience. Shurflo's <a href="/7568-shurflo-water-pressure-system-pumps-201165">water pressure system pumps</a> bring household-quality water pressure to RVs, campers, and off-grid cabins, automatically maintaining consistent flow from sinks, showers, and appliances. Paired with quality <a href="/7568-shurflo-water-inlets-pressure-regulators-201163">water inlets and pressure regulators</a>, these systems protect against overpressure damage while ensuring safe, controlled water delivery whether you're connected to campground hookups or running from your freshwater tank.</p> <p>Shurflo's engineering philosophy centers on low amp draw, quiet operation, and long service life—critical factors when you're dependent on battery power or limited electrical capacity. The brand's pumps feature built-in thermal protection and check valves to prevent backflow, and many models offer tool-free maintenance for quick diaphragm or valve replacement in the field. Whether you're outfitting a new vessel, upgrading an aging RV system, or replacing a failed pump, Shurflo delivers proven technology backed by decades of refinement in real-world conditions.</p>

Product Details

The Shurflo 9480003 is a genuine replacement check valve designed specifically for Pro Blaster II and Aqua King II series pumps. This essential component ensures proper one-way flow direction, preventing backflow and maintaining consistent system pressure in your water delivery system.

Quick and easy

great so far... I really hope that it is the right part.

Good products at a good price!<br>Never bought from them before, so I used Google Checkout, I always get nervous about buying from a new online store, but they came through just fine.<br>Shipping was a little expensive for the product I purchased and the shipping time, but was still cheaper than most anywhere else.<br>$12 to ship an automotive gauge [>2 lbs] and it was a 5 day ship.<br>Otherwise, a very good experience, B+ to A- just because of shipping cost/time.
