How to replace sprout seal kit?

I checked online at www.plumbingwarehouse.com/american-standard-kitchen-faucet-hamilton-4040. There is a diagram that shows a seal kit that probably needs to be replaced. The diagram is really good and shows a complete breakdown of your faucet. I hope this helps.

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.

Hi! If there are no leaks from around the spout, you can remove the spout and apply silicone lube to the spout o-rings and resemble. If it is still hard to move ,replace the o-rings.

If you have properly replaced the diverter assembly, there is either a problem with valve or debris was left in the valve from old diverter when new diverter was installed. Disassemble diverter by pulling spout back off. remove new diverter and check valve. Cup your hand over faucet and turn cold water handle on to attempt to flush any debris left behind. Try several times then reassemble. If this doesn't do the trick then replace. Get a quality filtering system and take care of your new faucet by making sure it's dry and polished after use. You won't be replacing your fixtures as often from calcium and corrosion.

You have to lube the seals. New seals will be much firmer than leaking ones...but clean and lube is necessary.

Replace the cartridge

spout seal kit , from what you described.

you must remove the faucet form the sink. under the plate in the middle is 2 screws. remove the screws to remove the body.

just pull straight up,wiggle back and forth,the o-rings are holding it on .

Hi buffy9,

I'm Harvet the Master Plumber.

Your question is: You have an American Standard two faucet in my kitchen and the base of the spout leaks at the base. How do you remove it and replace the washers?

Are we talking about an American Standard two HANDLE faucet or one of the single handle models?

Thank you,
Harvey your Master Plumber
