1. Way to Fix and Install Single Lever Faucets
Kitchen or bathroom faucets with an individual handle to control the mixture and
flow of water usually function for years without needing consideration. The whole
control unit may have to be replaced, when they do develop drips or flows.
As with shank faucets, the initial issue is disassembly. Faucet manufacturers hide
screws in spots --under handles or ornamental buttons--or remove them
completely. This tutorial should help you figure out how to get indoors of four
sorts of single-lever faucets. once indoors, you can see what type of control unit
the faucet uses.
As each firm makes its own, it is significant
to get indistinguishable replacement parts.
Consult the Internet for the manufacturer's
closest sales office; it will direct you to a
local components vendor.
Disassemble these faucets with attention,
noticing how components fit together--and
in what order--as a help to reassembling
them. Sketches can be quite helpful as a help
for reassembly.
1. The Ball Faucet
As the round shape of the faucet handle indicates, the control inside this faucet is a
ball made from brass, with three ports whereby water flows when the ports are
centered over seats in the faucet body. Underneath the shank of the handle is a
setscrew that must be loosened with a hex wrench to get the handle away. Don't
take the screw all the way outside; it is readily lost.
2. The Ceramic-Disc Cartridge Faucet

2. The screw that releases this handle isn't beneath the knob at which you may be
prepared to locate it. Lift the lever as high as it can go; recessed under it is the
handle that is released by a small setscrew. However, the control unit is currently
just partly uncovered; you must also remove the chrome body cover. To get this
done, disconnect the thumbscrew supporting the popup drain stick beneath the sink
(first mark the stick with a felt-tipped pen so you can link it in the same spot).
Subsequently unscrew the two Phillips-head screws on the underside of the faucet
and lift off the body cover. Newer variations have a slot screw in the handle and a
chrome ring that unscrews for easier accessibility to the cartridge.
3.The Tripping-Valve Faucet
Kitchens, although it is no in so called
because the hot- and cold-water inlets each
have a valve that points when lever is moved
forward, permitting water to pass through
the spout, this faucet is extensively used
longer To get into the faucet, turn the ring
counterclockwise with a wrench (if you use
a pipe wrench, be certain the wrench's jaw
are covered with electrical tape) until the
spout can be lifted off. Subsequently pry up
the chrome body cover with a screwdriver and lift it away.
4. The Sleeve-Sort Cartridge Faucet
The screw in the cover of the faucet handle exemplified is in plain sight, but in
newer versions it is concealed by a button the must be pried away. The faucet lever
lowers to turn it away and lifts to turn the water on. Inside the cover a cartridge is
moved by the motion of the lever up and down to turn the water on and off. An old
version of this faucet has a retainer clip in the outside of the handle that must be
pulled out for disassembly.
