90% of the time it is a broken stem that needs to be repaired on the 690 toro sprinkler system.
For most people this results in them throwing the whole sprinkler away and buying a new one.
Usually this runs you around $200 (give or take) per sprinkler.
Now there is a company see link below that makes replacement stems for the 690 series toro sprinkler systems. They usually run for $25 each. Once they give that replacement stem a try... I have seen them being used on Golf courses consistently after that. Way better alternative and without a doubt more cost effective.
Actually as of right now, this company is the only distributor of this replacement part (stem)

Having a sprinkler system is a great way to keep your lawn healthy and beautiful. At the same time, sprinkler systems can often lead to headaches. The irony here is that most sprinkler system problems stem from poor installation. Too many people try to save money by hiring poor installers. These are often people with no reputation and experience. Therefore, the consumer is mostly to blame. There are so many ways to research who you're hiring that it would be irresponsible not to do your homework prior to paying someone to do a job. That said, if you did make this mistake, then you're not alone. If you're having a problem with your sprinkler system, then you need to look into sprinkler system repair. The good news is that there are a lot of quality sprinkler system repair people out there. The first step is to find out how long an individual or company has been in business. You don't want to hire someone who is doing an odd job just to make a little extra money. You want to hire someone who knows the ins and outs of the sprinkler system repair business. After finding out how long they've been in business, call them and ask sprinkler system questions. You want to see how knowledgeable and confident they are before giving them your hard-earned money. Once you find the best sprinkler system repair option, ask to be on the scene while they perform the repairs. This way, you might be able to fix the issue on your own the next time a problem arises. It will also ensure that the workers don't be pulling any funny business in regards to creating a different problem down the road so they will get another call. Since poor installation is the most common cause for sprinkler system problems, the most common problem is a leak. A quality sprinkler system repairman should be able to fix the average leak in less than an hour. This should never cost more than $100. If they quote you more and it's only one small leak, then you need to go with someone else the next time around. On the other hand, if they fix the leak and they're reasonable with their quote, then you have found a good sprinkler service repairman.
