Abstract: A water treatment apparatus (10) comprising an elongate metallic brace (12) mounted to a wall (14). Components (16) are for connecting the elongate metallic brace (12) to an inlet water pipe (18) and an outlet water pipe (20), so as to electrically ground the inlet water pipe (18) to the outlet water pipe (20). The elongated metallic brace (12) will also reinforce and stabilize the apparatus (10) in an in line installation to the inlet water pipe (18) and the outlet water pipe (20). A housing assembly (22) has a lamp entrance (24), a water inlet port (26) and a water outlet port (28). The housing assembly (22) is prefabricated, so that it can be completely dismantled for cleaning and easily reassembled for use. A facility (30) is for fluidly attaching and detaching the inlet water pipe (18) to the water inlet port (26) and the outlet water pipe (20) to the water outlet port (28) of the housing assembly (22) for a quick in line installation.
