FAUCET SPRAYS
The heart of a faucet spray is a mechanism called a
diverter or butterfly valve located inside the faucet in a chamber just below
the base of the swing spout.
This valve normally permits water to flow freely through the spout when the
spray attachment is not in use. When the thumb-controlled valve on the spray is
open, an imbalance of water pressure is created to operate the valve.
A piston-like piece snaps down, shutting off most of the water supply through
the spout and diverting it through a hose which leads to the spray head.
This valve cannot be put into any faucet which was not originally made with a
chamber for the valve.
AERATORS
Aerators are attached directly to the faucet to prevent
water from splashing in the sink.
Stationary aerators create a steady flow of water in one direction; movable
aerators aid in directing water flow into the sink and supply either fine spray
or a steady flow.
Twisting or up-and-down motion on the movable aerator determines the type and
direction of the water flow. Aerators adapt to both inside and outside threads.
A snap fitting is used in place of an aerator as a snap-action hose fitting
for quick connection to portable washers and dishwashers.
Self-cleaning aerators are available. They automatically clean themselves
whenever the faucet is turned on and off.
WASHERS
Washers are one of the most basic plumbing accessories-
and the heart of many home plumbing problems.
Nylon or polypropylene washers are not recommended because they will not seal
under cold-water conditions. Urethane washers will seal under hot or cold and
are said to outlast rubber.
Leaking faucets are usually caused by washers that have been damaged by rough
faucet seats that allow foreign particles to embed themselves in the washers.
Washers in most faucets include top bibb, faucet and cone or "O" ring
washers. The faucet washer is located in the spout; bibb washer under the stem,
and "O" ring or cone washers in the handle stem.
A coupling washer is used in swing-spout faucets inside coupling nuts between
the swing-spout body and adjustable arms. Faucet aerators also have washers
between the faucet and aerator.
Sometimes faucets require repacking. Packing material comes in string and
washer forms. Graphite string packing is wrapped around the stem of the valve
under the cap nut. Washer packing consists of preformed cone-bonnet packing,
which fits over the stem of the valve. Tightening the cap nut forms a permanent
seal.
TOILET SEATS
Industry sources say that toilet seats are changed on
an average of every three to five years.
Better products have high-quality plastic or kiln-dried hardwood seats and
lids with tongue-and-groove fitting. Nylon hardware is sturdy and non-rusting;
metal hardware should be solid brass with chrome-plated nickel finish.
Some toilet seats have "easy-on, easy-off" hinge posts, which facilitate
installation by the homeowner. These hinge posts also make it practical to
remove the seat for thorough cleaning.
Many toilet seats are made entirely of hard plastic, which can be colored or
patterned. Better-quality plastic seats are manufactured so that color or design
is part of the plastic rather than a coating that can chip or wear off. Many
decorator toilet seats are the so called "soft seat."
