Pond Boss Forums AERATION Systems questions piston cup for brookwood 1/3 hp compressor

You can send it to Vertex for a rebuild and it costs $242 plus shipping. 844-432-4303 Since you know what part is broke, you might want to call them to see if they have a part to rebuild it. Typically the rebuild kits don't have the piston, just the sleeve and the "ring". They changed compressors in August 2013, so you have to determine the exact age of the compressor. Pre 8/13 compressors take a different rebuild kit. I have rebuild kits for the later ones, but no pistons. I *might* have an older compressor sitting here. Post the model number of the compressor and I can check it against the models that I have here.
