Recently my kitchen faucet had become hard to turn from sink to sink. I removed it and took the decorative covers off to clean the gunk out and lube it. I put it back in and it moves great from sink to sink but now it doesn't have very good pressure and whines on the hot side when the water gets hot, but only when the water gets hot. The low flow is all the time and on both hot and cold sides. I've disconnected everything and re-connected it to make sure i didn't have something too tight but that didn't help. Help me! I'm so frustrated at this.
