I have ordered a GL235-GLC-2P-A controler for my solar assembly I am installing it comes as a pkg and includes a 3-port 2" x 2-1/2" valve can somone tell me which ports are which size? I am having a hard time finding 2-1/2" PVC bushings. I assume all of the ports will be threaded? It is supposed to be here on Monday and I want to have everything I am going to need to get started with the installation. I have contacted Hayward and have not heard back from them, I hope someone on here has one or something similiar.
