We flushed our hot water tank and after that we have very little pressure our 122-426 b&K kitchen faucet. Changed the cartridge and cleaned the aerator

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.

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

SOURCE: FF-1800 HAS LOW HOT WATER PRESSURE AND DELAYED TIME TO GET HOT

Sometimes there is a lot of sediment released into the pipes (particularly hot water) when water lines are shut down and restarted as part of a remodel process.

Particularly with a pressure balanced faucet this can create all types of symptoms including those you describe...

Before you go to any expensive lengths, check any intake screens or strainers, both on the faucet and in the other components of the system. A lot of the time this will solve the problem...

SOURCE: Moen one handle kitchen faucet very low water stream

if the pressure is good with the head off then you can probably get a new head for it u shouldn't have to change the cartrige. it sounds like the head is clogged so plastic pieces in the head to help save water "water savers" it is hard to clean them i would try changing the head u should be able to find on for a moen, u buy for looks u buy it for life. take the old head with u when u go to buy a new one so they can match it up to the right one.if you can't find it and a lowes or home deptm try a plumbing supply house

SOURCE: No water pressure in kitchen sink. Not the aerator.

First of all we like to check the easy/cheap things first.

1. Are the shut-off valves closed lightly?

If they are closed, open them.....easiest fix of them all.

2. If the valves are open then possibly a washer is shifted.

Turn off the water supply at the valves under the sink. Remove the handles by removing the set screw under the handles. There should then be a packing nut which holds all of the "guts" of the faucet in. Remove this nut and pull out the long stem. On the bottom of this stem is a flat washer that may have been damaged or is just slightly shifted. EIther way, I would replace it if the faucet is more then a few years old as it is cheap and you already have access to it. WHen replacing the valve stem, be sure to use a plumbers grease on all rings and seals. The rest of the replacement is the same are the removal.



Hope this helps.
