very well made and approved for use by my water authority
these ZW valves are the best out there. Very well made and durable, thank goodness, because they are not inexpensive.

Works as it should.
Unfortunately in today's world, you expect something to like this to last 20 years, but chances are that the manufacturer gets sold every 5 years to another conglomerate so you really can't rate the quality by residential useage and how long it lasts. Even if it has no quality and doesn't last more that a year, complaining at that time will not fix it.
