I have a full bath in my walkout basement that is hooked up to an injector pump. I know nothing about this device... but it smells. The whole basement smells like a cross between musty old socks and sewage! What is causing this problem and what can be done?

Thanks-
Sandy

Is the smell worse next to the pit? Did it just start? Do you have two vents? One from the pit all by itself and the other venting the fixtures off the lavatory? Back to you, tom
