The water pump filter I have is pretty damned clogged up. Here is how I replaced the filter element.
Step 1: Preparing the Filter.
First I turned the top valve on the filter to lock off the water supply. Next I removed the clamp holding the filter.
Step 2: Getting the Filter Element Out.
Using the spanner for the filter I unscrewed the assembly. Now the element and holder are out. See how mucky the water looks?
Step 3: Cleaning the Element Holder.
Once I removed and discarded the old element, I cleaned the assembly to remove the algae.
Step 4: The New Filter.
The new element goes into the assembly jar with the rubber gasket up.
Step 5: Completion!
Screwing the assembly back in place and turned back on the valve on top, the job is done!
