Weak water pressure coming out of sink faucet only
I recently bought a house and the kitchen faucet has always had low/weak water pressure. The bathroom faucets and showers are great, I tried draining the water heater to get rid of mineral deposits which in turn I had to end up replacing my water heater because it quit working, and the kitchen still has weak water pressure!! Does anyone have any other suggestions??

The next step would be to disconnect the faucet from the supply under the sink and then check the flow directly from the "stop" valves under the sink. It could be you just have a lousy kitchen faucet OR that the internal passages are plugged with minerals. Some faucets have replaceable internal parts and this may be an option.

I will try that when I get home!! But so far I've taken apart the sink head, and handle cleaned it all out, and am afraid I'm gonna have to replace the piping under the house?!?!!!

Unfortunately, that is on the list of potential fixes at this point, Furd's test will help rule the faucet in or out.

If its steel pipe it may be corroded internally. and there is not much you can do. Was this a sudden issue when the heater was changed? Or always low pressure and the heater change made it worse?

It was always weak, I bought a new faucet, that helped for a few days, then when I replaced the water heater, it then went down to almost a trickle. I'm stumped! Because other than replacing the pipe, I've tried just about everything....unless my other thought was that it's the actual faucet, because it seems to have good pressure when I take it off and just let it run into the sink???

Yeah, if you have a flexable supply and remove the faucet side, aim it in a bucket and open the valve. If you get good pressure there its the faucet.
Sometomes yes you can remove the cartridge or stem then open the falve to flush it. Sometimes the cartridges get clogged and cant be cleaned. Replace the cart.
