I'm planning water inlet for house:
- For 2-4 people
- 300m2 garden watering system ocasionaly (there is seperate garden water inlet as well)
- Water comes in via 32mm PE pipe (internal diameter 26 mm ~ 1") from shared deep well pump.
Main question now - what should all inlet system connection sizes be? Valves, regulators, expansion reservoir (1" connector), check valves, meter, particle filter, water softener filter (1" connectors), etc., not including branch-off to kitchen/bathroom that would be different sized. My initial thought was 1", but some of those are more widely listed as 3/4" in local shops (regulators, meters).
Will 3/4" give any noticeable bottlenecks here? Should I go all 1" here?
