Not if you don’t mind changing them every 6-12 months.
You can get really cheap budget sprinklers for $1-5, but as with everything in life, you get what you pay for.
We only use Toro sprinkler bodies which have excellent seals, springs and general construction. Generally you can expect 7-10 years from a Toro which in the longer term is much better economy.
Every irrigation has a common wire that connects all of the solenoids together and in most cases it is a black wire, as this is the colour most commonly used.
The common wire is found in the ‘c’ terminal and is vital to the systems operation.
If a common wire gets cut then all of the solenoids that it connects together will be out of action.
Its usual to have one strand of multi core wire serving the front of a house and another strand serving the rear, so if you find that all of your rear solenoids have stopped working then chances are your common wire will have been cut or broken.
From there it just a matter of tracking it and repairing it.
If your sprinklers are barely spraying then it will be one of a few issues.
The most likely is that the system has a leak and pressure is getting released at a point other than the nozzles. Most likely is that a riser has broken and needs replacing.
Another possibility is that all nozzles are blocked. Rather than trying to unblock them you’re probably better off just replacing them.
Another possibility is that the solenoid has seized and is partially shut. This is the least likely option.
a) check for leaks around the base of sprinklers.
b) remove a nozzle and check to see if there is good water pressure.
c) if neither of the above resolve the issue then you may need to check out the solenoid.
By a process of deduction you should be able to find the problem!
