If you own a rental property, you know how important it is to keep up on the maintenance. A proper maintenance schedule will help reduce the need for costly repairs later. If your rental property includes a septic system, you owe it to yourself – and your budget – to hire septic services after each tenant moves out. Problems with your septic system can lead to some serious plumbing issues. Since you don't know how your tenants treat the septic system, there's no way of knowing when problems are going to pop up.
