Consider placing the fountain near a sitting area, deck area or patio. Or you might want to design a private sitting area in the garden with a wall fountain amidst a beautiful flowerbed. Japanese rocks or small pebbles make a nice addition to a fountain's water basin. Most wall fountains are powered by a submersible pump that re-circulates water from the basin through a delivery pipe up to the spout. Most have a jet of water spilling into a trough or basin.
Some wall fountains require piping behind the wall, which can get complicated.
Attachments for fountains will vary from one model to the next. Lighter-weight fountain kits are sold with mounting hardware. In cases where it's not possible to hide external tubing with plants or vines, use lengths of copper pipe to connect the pool to the fountainhead. The copper will gradually develop an attractive patina that will add to the character of the fountain. To determine the size of the pump required for a particular waterfall, first estimate the vertical height from the top of the pump to the top of the fountain.
