We highly recommend one of these inexpensive strainers be installed in every fresh water system. It protects the performance and life of your water pump by straining out sand and debris that fouls pump valves.
They're easy to install and even easier to clean out. The transparent design shows when it is time to clean the bowl. Just screw it off by hand, clean and reassemble.
Strainers are required to maintain warranty on Shurflo Revolution pump.
