How do you remove a richdel sprinkler valve, when I turn the body of it, it doesn't unscrew, it just turns in place.
is it the valve your trying to remove, or the sprinkler head? if its the valve, there will be two pipes, one in and one out, just unwind the thread at end end of the valve, If its the sprinkler itself, then there should be a pipe under the sprinkler(swing joint) just grab the whole body and unscrew ( make sure you grab the whole sprinkler and not just the top, you may have to dig around it
if the valve itself has gone bad, then you can actually replace it without haveing to remove it. richdells are now called irritrol valves. they are not that hard to replace the guts and top part of the valve. if you can find the same valve off the internet or a landscape store, just take apart the old one and replace the insides with the parts from the new valve, and replace the top piece with solenoid as well. if you cant find the same kind of valve, just dig up a nice hole and cut the pipes and replumb it. thats pretty easy too. the more room you have on the pipe to cut, the easier it will go. but richdells are now irritrols. the parts will be the same, just have a different label. ive seen the richdells last over 20 years though good luck and hope this helps
