Dear A1,
I was surprised to hear about the issues with the Liberty’s plumbing. It seems Marathon has a more comprehensive system with a manifold setup that allows for individual shut-off valves for each source. If you’d like, I can share a picture of how a properly designed water distribution system looks.
Is there a risk that Liberty owners might be drinking contaminated water?
On a positive note, great job on addressing the issue and implementing the fix!
