Using the flow diversion valve on a septic tank.
Hi:
I need to turn the flow diversion valve on my septic tank so it uses the second drain field, but the septic tank company is charging me $200 to come and do this. I know where the valve is and I also have the rod for turning it, but I have no idea how to do it. The septic tank company said if I don't do it correctly, I could end up breaking the valve so I should call them the first time and they can show it to me.
Any suggestions? I did not find any directions on the internet.
Regards,
K
