Sounds like your water supply lines under sink where they connect to faucet unit are loose oo they didn't apply plumbers putty under the faucet unit it self

check the aerators on the faucets. i know after i change a hot water tank there is always some crud that comes through the lines and gets stuck in the aerators, they are the part that holds the screens in place on the spouts.

The designs of the Kitchen Sink Faucet mainly exhibit differences in its handles and spouts. Differently curved spouts and handles diversify the range of products. Some have long spouts and some are with short ones. The spouting of water may also give different flow patterns with the external fixtures. The handles are mainly in single or double.

There is a good chance that if you remove the handle there will be a retainer of some sort. The retainer's job is to keep the stem/cartridge from pushing out due to water pressure. It may be in the form of a nut or a clip. Be careful removing the handle because if the retainer is completely disengaged then the stem/cartridge may shoot up. Turn the hot and cold water off at the valves located under the sink and relieve the pressure by turning the faucet on. If it's a loose nut it will spin freely. Tighten it. If it is a clip you may need to play with the stem/cartridge to align it properly before the clip will move into place..

Hi hi--
You'll need to rebuild or replace your hot water control stop--that's the valve on the faucet body. If it's a single handle control, you'll need to replace the control cartridge. If the faucet has two knobs, you'll need to locate whatever stem pieces are needed within the hot valve. Sometimes, on two knob faucets, you can get away with simply replacing the rubber pieces inside the control stem. If that is the case, your local hardware store should have manufacturer-specific rebuilding kits available. Be sure to locate the faucet's model name first! That should be written somewhere on the above-sink portion of the faucet body itself, and you should be able to see it without taking anything apart.

Option 1 ; Cap off the sprayer.  Option 2 ; Relocate the air gap as high as possible under the sink but then you have no drain under it in case it backflows (it is really a vacuum breaker ,  one way check valve) Option 3: Take back the faucet and get one of those that the spout is also the sprayer.

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.

All faucets have a hot and cold line input. The single handle units have a mixing valve within the handle. Aside from removing the water lines there is usually some type of connecting bolts for the base plate as well that will need to be removed prior to removing the faucet. Do not forget to turn the shut off valves off at the wall before you remove the water lines.

Good Luck

I would check the strainers on the intake and the faucet spout. It is possible that sediment has built up and now is impacting thermostatic flow from the faucet... if one side is clogged its hard for the faucet to balance... try the stainer on the spout and any other strainers that may be on the supply hoses, valves, intake, etc...
