Simple Plumbing Repairs in the Home

by George M. Warren

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.

FAUCETS

SEAT WASHERS

Badly worn washers make faucets noisy, hard to operate, and wasteful of water. Moderate force on the handle of a faucet in good repair should stop all flow and drip. [Figure 1] shows an ordinary half-inch T-handle compression faucet which closes against the pressure of the water. To replace the seat washer, shut off the water to the faucet. Unscrew the cap nut with a monkey wrench. (Placing cloth or thick paper between the jaws of the wrench saves marring the cap nut.) Take hold of the faucet handle and unscrew the stem from the body of the faucet. With a screw driver remove the washer screw at the bottom of the stem. This screw is often hard to start. Applying one or two drops of kerosene and lightly tapping the head of the screw may help to loosen it in the stem. Use strong, even force on the screw driver, the blade of which should have a good square edge to fit the slot. The head of the screw often splits before the shank of the screw turns in the stem, because it is already corroded and weakened. If it splits, deepen the slot in the head with a hacksaw, cutting a little into the shank of the screw. No harm is done if the saw cuts slightly into the stem of the faucet. The washer screw may now be turned with a small screw driver. Replace the old washer with a new one, replace the washer screw, screw the stem into the faucet, and screw down the cap nut. Rubber and fiber composition washers for hot- or cold-water faucets cost 10 to 15 cents a dozen. A "floating" washer, costing 15 cents, is very serviceable. A few washers of the needed sizes should be kept in the home. If none are at hand, a temporary washer may be cut from a piece of leather, rubber, or sheet packing. Leather is preferable on cold-water faucets and rubber on hot-water faucets.

[Figure 2] shows an ordinary ³/₈-inch, 4-ball-handle compression faucet for a washstand. To replace the seat washer, shut off the water to the faucet and open the faucet one or two turns of the handle. With a monkey wrench on the hexagonal part of the stuffing box unscrew the stuffing box from the body of the faucet. Lift out the stem, replace the old washer with a new one, as previously described, and screw the stuffing box into the body.

A worn washer with constant leakage over the seat of a compression faucet, together with grit lodging there, often causes the seat to become cut, nicked, and grooved. The trouble occurs more often in hot-water than in cold-water faucets. Such seats can easily be reground or squared with a simple seat dressing tool, two types of which are shown in [figure 3], A and B. A seat dresser with four cutters for different-sized faucets costs about $2, and its use saves buying new faucets. To dress the seat of a faucet, unscrew the stem from the body to the faucet, as above described. Screw the adjustable, threaded cone of the tool (see [fig. 3], A) down into the body of the faucet, as shown in [figure 3], C, thus centering it over the seat. With the hand, as shown in [figure 3], D, gently rotate the wheel handle at the top of the tool several times, and the cutter on the bottom of the stem squares the seat. Turn the faucet bottom side up and shake out the cuttings. Reassemble the faucet and turn on the water to wash out any remaining cuttings.
