When putting in a sprinkler system in a climate where it freezes, do I need a releif vale to keep pipes from bursting in winter time? Is this fact and where is this located in the system?

According to the Dripworks catalog, a relief valve isn't necessary, but here are some steps to follow. First, system timers should be brought indoors for the winter; remove batteries. Turn off the main water supply and drain all manual valves. Empty any canister filters, or open the drain valve to let water out. Install drain valves in the pipe at the lowest points in the system.

If you want to order a Dripworks catalog, call them at 800/522-3747. Hope this helps!
