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.

Compatible Pump Models:

  • Pro Blaster II series 4148 pumps
  • Aqua King II series 4158 pumps

Check valves are critical wear components in demand pumps that should be inspected regularly and replaced when performance degrades. This OEM part ensures proper fit and reliable operation, restoring your pump to original factory specifications. The check valve prevents water from flowing backward through the pump when it cycles off, which helps maintain prime and reduces unnecessary cycling.

Key Features:

  • Genuine Shurflo OEM replacement part
  • Direct fit for series 4148 and 4158 pumps
  • Prevents backflow and maintains system pressure
  • Helps reduce pump cycling and wear
  • Easy to install during routine maintenance

Regular replacement of check valves during pump maintenance extends pump life and ensures consistent water delivery performance in RV, marine, and mobile applications.

Easy ordering

Love the amazon checkout

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.
