Here are the pictures of my setup using the suction (skimmer) for a pool cleaner.
This picture shows all the pieces laid out in the order they go in:
This picture is the suction regulator valve that came with my Kreepy Krauly. It is spring loaded and opens up in the skimmer to allow some flow to the skimmer. The more suction you have, the more it opens up.
This picture is showing the skimmer plate that the regulator sits in. The basket is installed below.
The last picture has the hose connected. The plastic clamp is needed to keep the smimmer plate secured because when the pump shuts off for the day, there is a momentary backflow that can unseat it. There are also 4 little cheap valve-like things that open and then close.
Your biggest challenge to make a system like this work for you could be an issue with the dimensions of your smimmer box. That skimmer plate is a custom Kreepy Krauly part made to fit 2 different diameter skimmer openings. When I bought my Kreepy Krauly, there was a coupon in the box to order these parts for $5. Otherwise that is probably $65 worth of parts. You must have enough depth as well.
The biggest concern with all suction side cleaners is preventing air from getting into the system. That can be caused by parts coming loose or a hose splitting after a few years. There is nothing worse than coming home from work and finding that a hose split... and that your pump has been sucking in air for a couple of hours. When that happens, your pump seal is trashed. Ask me how I know
. Next job.. pump rebuild.
But seriously, if all pieces are secured properly, the hoses will last about 4 years, and frankly, here in Florida, I can usually only get about 4-5 years from a cleaner before it begins to deteriorate or you can no longer justify expensive repair parts.
