Diagram-Type Faucets

DIAPHRAGM-TYPE FAUCETS

  • The diaphragm faucet is washerless but is similar to washer-type faucets. A rubber diaphragm between the stem and seat creates a straight-down, frictionless close. As with washer-type faucets, diaphragm faucets have two handles.

  • Remove the stem by following the steps outlined for washer-type faucets. Instead of a washer on the end of the stem, you'll find a swiveling disc. If the rubber diaphragm doesn't come out with the stem, it is still inside the faucet.

  • If the diaphragm didn't come out with the stem, use pliers to peel it from inside the faucet and pull it out. Install a new diaphragm around the swiveling disc, then replace the stem in the faucet.

  • If the faucet is leaking around the stem, replace the stem's O-ring before reinstalling the stem.

How to fix a leaky Moen faucet that leaks at the spout ,which is separate from the handle?


These faucets can leak in three different places:

  1. Internally at the valve seat
    You'll see water dripping from the spout. This means the rubber washer is worn or damaged. To replace the washer, remove the decorative cap from the handle. Remove the retaining screw and pull off the handle. Remove the decorative cover, called an escutcheon, if there is one. Unscrew the packing nut counterclockwise. Unscrew the valve stem and remove it. Remove the screw that holds the rubber washer in place. Because these washers come in many shapes and sizes, you'll want to take the old one to the hardware store and buy an exact replacement. Be sure to buy two washers so you'll have one for the other valve. Replace the washer and reassemble the faucet.
  2. Around the handle
    If you see water coming from below the handle, the packing nut is leaking. Older faucets have a string-like graphite packing material wrapped around the stem. Newer faucets use an O-ring. First try tightening the packing nut clockwise... about one-half turn. If this doesn't stop the leak, remove the packing nut and replace the packing or O-ring; then reassemble the faucet. If the valve is using the graphite packing material, it might be a clue that you should shop for a new faucet.

  3. Between a pivoting spout and the body
    The spout might be held in place with a packing nut, similar to the faucet stem, or it might have a nut at the top of the spout. In either case, remove the spout and replace the packing material or the O-ring seal. Then reassemble the faucet.
Single lever faucets also are known as "washerless" faucets. They are easier to repair than compression faucets after you determine what type of faucet you have. There are three types of washerless faucets: ball, ceramic disk and cartridge.
Leaks are evident in two places... dripping from the spout and seeping from around the spout where it joins the body of the faucet.
Leaks from the spout indicate that the ball, disk or cartridge is leaking. To repair, turn off the water to the faucet, then remove the handle. The handles on ball-type faucets are held in place with a setscrew that requires an Allen wrench to loosen. Ceramic disk and cartridge-type handles usually are held in place by a screw hidden beneath a cap.
On ball and ceramic disk-type faucets, remove the ball or disk and replace the seals. You can buy replacement kits for these faucets at the hardware store or home center.
On cartridge-type faucets, remove the spout and pull out the retainer clip that holds the cartridge in place. To remove the cartridge, pull on the cartridge stem with a twisting motion. If it resists, install the handle so you can a better grip on the cartridge to pull it out. Take the cartridge to the hardware store or home center and purchase an exact replacement kit.
Reassemble the faucet according to directions.
Leaks at the spout-to-body joint indicate an O-ring failure. Disassemble the faucet as described above. Remove the spout sleeve and replace the O-rings. It's a good idea to replace these seals if you have the faucet disassembled for repair of the ball, disk or cartridge.

If a faucet is leaking the necessary repair will be either:
1. For a ceramic or washerless faucet, replace the cartridge.
2. For a typical old fashioned faucet, open the faucet, replace the washer (and packing if it has any) and verify that the faucet seat has not eroded.
The newer washerless faucets cannot be repaired except by replacing the cartridge. Cartridges for most common faucets are available at most home improvement stores or plumbing supply houses.
It sounds a lot more difficult than it really is, just shut off the water (usually a shut off valve under the sink). After the water is off, remove the handle and any chrome protective covering. Depending on the faucet type, it may be a little difficult to remove the cartridge since they are often covered with mineral build-up or corroded into place.
Once you remove the old cartridge the new one usually goes into place easily.
NOTE!!!
For single handle faucets, make sure you put it in the right way, some of them will put the hot to the wrong side if you put them together backward.

Faucet Repair


A noisy washer-type faucet is usually caused by a loose seat washer. To stop the noise, first turn off the water and take the faucet apart as described previously. If the washer is loose, tighten it or replace it. After threading the stem back into the faucet body, try moving it up and down. If it moves, the stem is worn and the entire faucet must be replaced. Some faucets are noisy due to poor design and construction. The only way to solve this problem is to replace the faucet with a quality one.
