H HOW BEST to make small plumbing repairs is a problem that comes to most householders, as it is sometimes difficult to secure the services of a plumber. In such situations a little knowledge on the part of the householder often saves much delay, trouble, and expense. Where local or State plumbing regulations are in force, and extensive repairs or alterations are contemplated, the householder should make sure that the work is duly authorized and is done by a properly qualified plumber. Few persons realize the potential danger lurking in leaky waste pipes, drains, and sewers, or in piping between systems, whereby sewage or an impure water supply may even in the slightest degree gain access to a potable water supply. In making repairs it is often necessary to tighten or to loosen a screw or nut, and the householder is sometimes uncertain in which direction it should be turned. To screw or tighten an ordinary right-hand screw, nut, or bolt, first think of the head of the part to be turned as being the face of a clock and the screw driver or wrench as being the shaft which turns the clock hands, and then rotate the tool from left to right, in the same direction that the clock hands move. Conversely, to unscrew or loosen, rotate the tool from right to left, in the direction opposite to clockwise. Small brass screws and stems are easily twisted off and rendered useless, especially if a large tool is used to turn them. Undue strain should be avoided, as it may result in the part or parts being broken at an unfortunate time. |
