Grajeda has chosen a classic hand-painted Grecian urn (figure E) as the centerpiece of the fountain. To prepare the urn for the fountain piping, drill a hole in the center of the bottom of the urn using a 1-inch drill bit. Be careful not to apply too much pressure, or else the pottery may crack. Slide the urn over the tubing so that it rests on the concrete pedestal (figure F). Be sure that it's stable and level.
Fill up the rest of the basin with more cinderblocks as supports for the rock pool. Attach a 500-gallon-per-hour, submersible pump to the PVC piping at the base of the pedestal. Drill a hole in the side of the tub, just beneath the rim, and pull the pump's electrical cord through it.
Cover the cinderblocks with scrap pieces of flagstone to make a stable base for the rock pool. Leave gaps between stones so that you can access the pump for any maintenance and so that the water will flow down into the basin.
Step Three: Filling in the Rock Pool
Grajeda has chosen Mexican Black La Paz pebbles for the rock pool. The smooth, polished, black rocks contrast well with the urn. La Paz pebbles cost about 50 cents per pound at masonry supply stores.
Before placing the rocks, cut plastic honeycomb panels to fit around the fountain to cover the gaps between the flagstone while allowing water to flow through. Also cut out a piece of the honeycomb over the pump area so that you can access the pump for maintenance without removing all the rocks and honeycomb.
Clean the rocks by filling the bags they come in with water from a hose. The dirt will settle to the bottom of the bag. Cover the top of the basin--and extending slightly beyond it--with the black rocks. Then fill up the basin with water, plug in the pump, and perform a test run to make sure it's working properly.
Step Four: Accessorizing the Yard
