Hey everyone, I hope you can help solve my problem. I had a leaky Delta ball faucet so I replaced the springs and seats, put it back together and now just a trickle comes out, the water pressure doesn't change when on hot or cold. So I took it back apart and replaced with original seats/springs and the same thing, no pressure. Took it apart again and left it apart and turned on the water and it came out full blast threw the two holes along with black chunks that looked like old washers? Also no I am now unable to turn off the valves under the sink and have to turn the main water off. Are those black peices part of the valve that was under the sink? Do I just need to keep flushing out the lines? Any insight will be great. I just hope its something easy!
