That was excellent feedback. Thank you very much. It sounds like a 1" tap with a 3/4" meter is ideal for brand new construction where the utility will be expanding their mains and guaranteeing good pressure. For retrofits, sloped ceilings, and other tricky situations - it depends.

Homes with steeply pitched ceilings may require the designer to include extra heads in the design area. Residential heads are not listed for ceilings with pitches greater than 8 in 12. I believe a 2" water line into the structure would be the safer bet no matter what the design of the house is. G.
