Thanks for the diagram. That all makes sense if all's working as designed.
So, it leads me to believe that we might have a bad check valve at some point in relationship to the holding tank..
Stages of Discovery:
- Disinfected, drained the holding tank and did not refill.
- Began running off city water with holding tank empty. Water was immediately foamy when not foamy before.Was not foamy before...prior to the disinfecting ?
Now foamy cause there is/was trapped air in system
