Hi everyone, I am currently in the process of building an additional 2bath house on my property. Current house is a 1bath unit with 18 WFSU. We have a 3/4" meter with a 3/4" line to the existing house with 80 psi pressure at the first hose bib.
New addition: The GC is planning to tie in a 1.5" inch line to the existing 3/4" line before it enters the existing house, and take this 1.5" to the new contruction about 100 feet in. Then it will reduce to 1inch in the additional house. The new construction will also have 18 WFSU.
My questions are:
1. With a 1.5" line added to the existing 3/4" meter and 3/4inch existing house line, will we see an adverse impact to the current house water flow? Will the magnitude of this impact be a lot?
2. Can a 1.5" line be added to the current 3/4" line? The WFSU charts show a max of 1 1/4" line for fixture count calculation.
Thank you for your time!
