The State of New Jersey requires that your Pressurized Vacuum Breaker be tested each year by a licensed back flow preventer specialist. This plumbing device which is right after the point of connection to your water line, provides the peace of mind that once water has entered the sprinkler system and its lines, that this water will not re-enter your home plumbing system again. We offer this service for a nominal fee. Please call our office to schedule this important service.
