With our new property in Bristow we now have two septic systems. One a traditional system and the small house has an Aerobic system. I've added the "chemicals" recommended to help promote bacteria growth, etc. The issue I'm having is the shower and sink in the master bath is having draining issues. They are quite slow and almost certain it is mostly the ladies hair that is causing the slow draining. I can go under the sink and take out the trap and make sure that is cleaned out. Also what to know what, if any product that can be used to pour down the drains to get them cleaned out but is not harmful to the arobic system. I know there has got to be some toothpaste, soap and makeup that can play a role in slowing down the flow of water. What can you recommend to open up these drains? Thanks for the help.
