Here I thought this would be a simple matter. The toilet I''m planning to use is a manual head. There will be NO overboard discharge of waste due to Lake restrictions. I''m told this head pumps the waste manually, that is a pump handle, to the holding tank. My impression of the vented loop theory is primarly for systems that have a through-Hull overboard discharge for waste when in outside the 3 mile limit.
If I''m reading all this great info right, It would be a preferred situation if the tank inlet from toilet is lower than toilet discharge. RIGHT !! Ok Guys, thanks,
