My entire backyard irrigation went out.  My neighbor and I worked the control box and couldn't fix it.  I called Moreno Lawn Care(the company maintaining the HOA property).  They came out the same day and diagnosed the problem.  A part with wiring was defective.  They came out the next day and replaced the part.  My cost for 2 visits part and labor was very reasonable.  Their phone number is 602-618-1531.
