My water sprinkler system guy tells me that my "Pressure Vacuum
Breaker" may have to be replaced. Unknown to me, it has been leaking.
He tells me this is a "backflow" device that keeps the irrigation
water separated from the home-use water. This concerns me from a heath
perspective. Can the two water supplies mix if the backflow is not
working properly? He say it costs about $200 (including labor) to
replace the entire device. Is this price reasonable? Would appreciate
responses from posters familiar with such systems and this backflow
device. Thanks in advance -- Brian.

I'm not a plumber and I don't know what a backflow preventer costs, but in
downstate NY, plumbers and electricians get around $150+tax for a service
call, so it doesn't sound unreasonable to me
