I apologize for not responding yesterday. I got a bit busy. Have you solved your problem yet? Your SWG should be one of the last components in your system, which means it should receive only filtered water. There shouldn't be any debris large enough to clog the SWG.
If you still need help, please complete your signature in your profile. We need to know what type of equipment you have. Also post a few photos of your entire equipment pad. We should be able to narrow things down for you. Initially, everything is pointing to a problem with the filter.
