I had an air leak from my diverter and once I opened it up I saw that one of the 2 small O-rings on the diverter stem was distorted. I changed all O-rings and now I have a terrible air leak when I close the spa and open the pool side. I opened the diverter again and now see that the gasket that goes around the 270056 diverter is coming apart on the bottom. Now I'm not sure why I would lose my pump prime but I am. Regardless before I order a new assembly I was wondering if they sell just the rectangular gasket since there are 2 screw that basically hold in it place.
