The most common problem with the multi port valve on a sand filter is the “spider gasket” (711-1910b), but replacing it can be a bit complicated. There are three different solutions for the repair. The easiest is to replace the entire internal assembly (600-9600)this method allows you to keep all the filter hoses attached and just remove the six bolts at the top of the valve. The assembly can only be re-inserted one way because of the notch in the side of the lid (you can’t mess it up).The second method is replacing the “plug” this method has the gasket already secured to the diverter but does require removing the handle and compressing the spring. The hardest but most economical fix is to replace the spider gasket only, but this entails removing the old gasket and properly securing the new gasket to the plug. Securing the gasket to the plug requires a level of expertise.You can try using 2 or 3 drops of super glue to hold it on to the plug. All these parts are available at http://www.waterwayparts.com
