Some key symptoms to look for include visible pests, damage to the system components, and decreased irrigation efficiency. To solve the problem, you'll need to inspect the system for any entry points or water sources that are attracting pests, and then take steps to seal up those areas, eliminate standing water, and maintain the system properly.
