Hi ssam1

I'm Harvey the Master Plumber.

You want to know if you can fix a sudden low volume /pressure delivery problem on an American Standard model AS4205100 H7, one hole / single lever with pullout spray And is it fixable by owner?

Yes and maybe!

All plumbing systems are plauged with debrie buildup. Every time you turn on a faucet the water starts moving and will bring bits of debrie up from the water main or well. Most are small and will pass through to be caught by the screen in the aireator. Sometimes a relatively large piece comes along and dosen't make it through to the screen. It is stuck in the body of the valve.
Fixing takes a little mechanical ability.
First, turn off the water to the faucet in question. Then carefully disasemble paying close attention to the order of disasembly so you can reverse the order when putting back together. As each part is removed inspect it for that troublesome bit. I find that a little bit of wire or a paper clip is helpfull. Carefully reasemble. If the volume is still low then you missed finding that bit. Try again or call in a local pro.

Your problem is a simple one.

1. Turn off water to faucet.
2. Place a towel(s) in the base of the sink(s) to prevent any parts from going down drain.
   
3. Remove the handle to the faucet. (single handle only)
   
4. If not a single handle then remove spout from faucet.
5. If a single handle remove cap carefully and any loose parts.
6. Gently turn spout side to side while lifting to remove.
7. You will see a hole with a very small valve where the water comes out to the spout on the base of the faucet.

1. Remove this valve (which is a backflow preventer) and replace.
2. Reassemble and test.
   

Problem solved.

It could be one of two problems, one simple, one serious.

• Easy fix
  

1. Turn off hot water angle stop under sink to faucet.
2. Remove supply line from hot angle stop.
3. Place end of supply line in a small bucket to catch some water.
4. Turn on cold water for a couple of seconds and backflush debris from faucet.
5. Reconnect supply line.
6. Turn on angle stop and test
   

• Complex fix

If you have steel pipes you may be experiencing reduced flow due to corrosion in your pipes. Reduced hot water pressure in the kitchen faucet is usually the first sign since this is the faucet that is most used in the home.

Repiping is a job for a professional. Another symptom you may need a repipe is orange colored or rusty water.

SOURCE: side spray has very low pressure

Disassemble the sprayer and remove the dirt and dibri gathered inside.

Reassemble.

Has the water been turned off to that faucet, or the entire home recently? If yes, it probably loosened sediment in the pipes and its clogging the sprayer.

No a pull out sprayer problem is different.

First try this. Pull out the sprayer and remove from hose by turning nut that connects sprayer to hose. If you can get someone to help you it would be nice since the hose can go down into the faucet and might be trouble to retrieve. Look in the connection on the sprayer where the hose connects and look at the screen. If the screen is plugged or dirty clean and reinsert. If you can't clean it replace it. If this isn't working go to the next suggestion below.

In the spray head of the faucet there is a build up of deposits from use and or water hardness. Here is the link to the Delta site.

Delta Faucets

If you find you faucet model order a new spray head. Once these go bad they usually need replacing.

Hope this helps and please rate this!
