Frequently Asked Questions
How do I flush my pre filter?
It is easy to flush a pre filter. There are no service packages involved and you can easily flush the filter on your own with a twist valve.
How often should I flush my filter?
Tip: place pail below the filter when flushing. You may use the flushed water for washing the floor or watering plants.
Are there any parts that require maintenance?
Unlike foam filters, the stainless steel filter mesh does not need to be changed. It can last several years.
Incoming water pressure flushes out sediments and clears the mesh. You may require a filter scrub every 3 years to remove stubborn particles that have lodged in the mesh.
