what Are the Pros and Cons of Having an irrigation master valve?


  • Fail-safe valve
  • Greatly reduces any water loss due to a leaky station valve
  • If your mainline breaks, the master valve allows the mainline to be repaired without shutting off the water supply
  • Can be used in conjunction with a flow sensor and controller that detects flow rate change (Highly Recommended)


  • Leaks can be overlooked when systems run at night
  • Stretching and contracting of the pipe can occur leading to mainline pipe failure, especially at higher pressures
  • Chances of water hammer can increase if there is a pinhole in the mainline or leak in a zone
