n some previous threads we've talked about modifications to Savio skimmers so i thougt I would post some pics on increasing the flow internally. Savio compact skimmers are made to house a single uv light which highly restricts the internal flow. If you're not going to use the internal uv light "ever" this warranty voiding proceedure might be just for you. I like the size and durability and just punch a hole in the center of the bottom as an outlet. I just wish I could buy a large basket to replace fill the entire space. First disassemble the filter by removing the uv light holder on top. You can then see the diverter plates inside that will have to be remnoved. These are here to send the water up and around the bulb assembly. As we go along if anyone else has any mods to add please do so. :yes:

Then remove the two screws holding the center plate that supports the basket and pads. This exposes the diverter plates. The easiest way to cut them off is with a cutoff wheel on the end of a drill or die grinder.

How interesting, the upload proceedure is reversing the order of some of the pics. Now we need to open up the passage through the divider plate. First seperate the back of the tube assembly by removing the two screws holding the two pieces together.

Then cut off part of the inlet plate just below the section that juts out. This is here to hold the basket away from the opening so just remove the lower part. In the previous pic it's already finished bceause the original pic was blurry.

I then open up the sides with a 2 3/4" or 3" hole saw. Your cutting a "half hole" so be careful center the hole saw leaving the band at the bottom for strength. You could also do this with a sabre saw.

Next I punce a couple of 1" holes up the sides with a hole saw. Two is plenty because above that is above the basket line.

Next we must modify the back side of the tube assy. This section is now just used to hold the center edge of the pads when reasembled and diverts water in fron of the pad and through them. With a 1 !/2" hole saw cut half holes in the upper portion of the slots carefully leaving the bungs for the mounting screws intact.

Next punch four 1" holes up each side carefully centering the hole saw between the ridges that hold the pads and the groove area in the edge. I would not cut this entire area with a saw because you need the ribs left between the holes for strength.

Debur all you edges and corners and reassemble. The pads are now the only serious restriction in the skimmer and the pad material could be replaced with a slightly more open matting if you wished. You could also eliminate them all together along with the back side of the uv tube area and put something else in there. I would be happy with one large basket assembly alone. We need a replacement basket for these! :thinking: :yes:

Do you have an estimate of max flow?

With the 8 1/2" faceplate Savio says 1200-3500 gph but I think the 3500 gph would be really pushing it. I know when it gets close to 2500 gph there was a 4" minimum drop in water level from intake to center chamber so that's why I cut them up. After opening them up the restriction then lies in the pads. They're very tight. A more open matting would be a good solution. Savio is using these as a large part of the filtration where I just use them as a skimmer. As for total flow after modification I'm not sure but seeing a 1" drop makes me happier.
