Step 1 : Make a plan
Use graph paper or a scale ruler to prepare an accurate scaled drawing of
your property. Include buildings, patios, walks and driveways, fences
and other obstacles. Designate lawn, garden, shrubs and additional types of
plantings. Indicate the location of water lines, water meter and outdoor
spigots and where you want to locate the control valves. To accurately
determine the pressure and flow capabilities of your water source do some
investigating. Use a pressure gauge to test the water pressure at your
outdoor spigots. Look at the size of your water meter and outside diameter
of your water service line and hose bib piping. With this information, use
the manufacturer's guidelines to determine the appropriate components for
the yard's in-ground system.
Depending on the system selected, you may be working with rigid PVC
pipe, which is joined with fittings that are solvent-welded together.
Other systems use flexible poly pipe, which is joined together with barbed
fitting and hose clamps. Either piping method is easy to work with and
requires only hand tools.
