I'm going to put in some irrigation for a new client who says he has salt in his water.

The existing landscaping has been living off the water for two years. No severe problems seem apparent on any of the existing plumbing. I've been asking everyone I know about salt water on irrigation in the local area ( very inland ) and I've been getting a wide variety of answers.

My question is,

Will an inland water source that is saline water corrode brass ball valves or the metal components of irrigation control valves ?
