I live in an upstairs duplex unit which has its own main water turn off in
the basement. I had to turn off the water at the main valve in the basement
in order to clean out the trap in the kitchen sink(there are no valves
underneath the sink for the hot and cold water faucets). After cleaning out
the trap, I turned the water on again at the main valve in the basement. The
hot water in the kitchen sink runs fine but the cold water is just barely a
tiny trickle. Both hot and cold water run fine in the bathroom and in my
washing machine. Any ideas on why the kitchen sink cold water is not running
at normal volume and what I can do about it? Thank you very much!!
What trap were you fixing....you don't need to turn off water for a drain
trap, so you must be referring to some screen filter for the faucet.
Assuming there is a screen upstream of the faucet, perhaps some crud got
past the screen while you cleaned it and is now clogging the cold side of
the faucet. You'll need to turn the water off again and take apart the
faucet valve. See if something has lodged in that valve.
Clarifying what trap you cleaned and the type of faucet you have (single
handle, 2 handles, brand) will aid others in providing a better answer.
