Oh, I thought of another question:
* What is the typical plumbing guarantee on installation/labor? 1 year? 90 days?
If we go with a new system, plumbing work will likely be needed. The current system is installed in a very convoluted manner. I'd like to upgrade to 1" if we can if if that will help flow/pressure.
It would seem that plumbers of good workmanship skills should warrantee their installation for some sort of time frame. It would not be good to have everything installed, spring leaks shortly thereafter & have them say, sorry, only parts are warranteed.
