Product Description: Simple installation: no plumber, easy to assemble yourself, two installation methods (wall or toilet mounting) Content: 1 sprayer. 1 hose. 1 hook. 1 adhesive tape. Installation Tips: Be sure to connect the flare nut end of the hose to the showerhead and the hex nut end to the T-valve. 2) Do not connect too tight or too loose. 3) Use the washer attached in the packaged box, larger for tank and water supply connection, smaller (normally already in hose end) for bidet hose and bidet spray head. 4) Unplug the T-valve adapter after each use to shut off the water supply to the bidet spray head. If you decide not to turn off the valve lever, you risk loosening the internal components of the sprayer and hose or subjecting your home to water or flood damage.
