To allow individual maintenance, where does good practice and code generally require shutoff (angle stop) valves in a dwelling?
a.Only at the meter
b.At each fixture supply (for example under lavatories and at water closets)
c.Only at the water heater
d.Nowhere inside the dwelling
Giải thích
Fixture shutoff (angle stop) valves at each fixture supply let a single fixture be isolated for repair without shutting down the whole house. Valves only at the meter or heater, or none at all, would force a full shutoff for any minor fixture repair.
