Hi, I was told by my gardener that I need new sprinkler valves and each of those run about $50-70. I looked up online and I found them for $20 or less. Also what is the basic labor cost for getting them installed? I got estimates that range from $300-1000. I am confused.
If it is $50-$70 installed, that is a good price. Where I work, we get $125, and that is about the going rate in the north east. If you want to do it yourself, do not use Toro valves, Toro is garbage. Hunter, Rainbird, Irritrol, and Weathermatic are all good valves. Dig a nice big hole where the valves are, longer on the downstream side of the sprinklers. Cut the line coming out of the valve, and unscrew it. If it is a tight fit, take the valve apart and unscrew it. If you have to take the new valve apart to put it on, There are only 3 parts inside, so don't worry about not being able to put it back together. From top to bottom, they are the spring, the rubber diaphram and the plastic ring. Then reconnect the lines coming out of the valve. Then connect the wires from the solenoid. 1 wire from each valve gets connected to the common wire. Look in your timer to see what color it is. Then the other wire gets connected to individual wires. Check the order of the wires to the valves. Write it down. This will help keep the valves in the same order they are in now. The prices you got 50-70 is what your gardener told you for each (i am assuming that he is installing them.) The 300-1000 just estimates for installation from different contractors. Unless you have 8 valves or more, the $1000 sound real high. You do not have to be a plumber to install the valves.
they screw in and out, acouple of wrenches, a shovel, a roll of teflon tape, all less than 300$
