@twilliard that was very informative, but what would the maintenance consist of on a skimmer
Maintenance
That is an excellent question about skimmers.
I like to see it as ease of access to all components. Lets start with the body. There are skimmers for instance where you have to try to reach your hand in through the neck for cleaning. What if the neck is 2.5" and the body is 10" tall and 8" in diameter? Getting a wrist in is difficult let alone reaching 10" down for cleaning. Now if the bottom is removable then the task of cleaning can be done with ease.
Next lets move to the pump.
Where is it located and how is it connected.
Ever had a pump connected by unions on both the intake and the output? How many times has a person over tightened the unions just to find they are not easily removed (especially on larger unions).
How is the impeller cover made for removal?
Ever had the type where they twist lock in place having to match up the shaft while lining op the cover tabs? Now that is a task within itself.
Take this pump for instance

Next I would move on to the venturi
Everyone knows calcium/salt deposits are a pain in the air intake on venturies.
Look closely at how they are made. Some are easier than others to clean this deposit out.

These are just a few of the most important features a skimmer should include for ease of maintenance.
