No cold water.

 In the same are two kitchen sinks. Sink number one works
great. A couple feet away (in this little church) is sink number
two.  It has no cold water but hot water works and occasional
it will cough and sneeze hot water (from trapped air pockets.) If
you're nearby you will be splashed unexpectedly. This sink has
a cold/hot valve under the sink. They're open all the way. The
water comes from a well and isn't salt treated. Valves get stuck
often. It's so stuck that in order to shutoff water, we'd simply cut
power to the well pump. How do I unclog the kitchen sink cold
water line?

Thanks

  Leroy,

   You need to find the clog. Turn off the well pump or shut off the main
valve, disassemble the sink faucet, put a heavy bath towel over the faucet
body, and turn on the water for 10 seconds. Continue in this fashion until
you locate the clogged valve then clean and rebuild. You should be able to
find or map the clog in this way so that you can clean or repair clogged
valves or find and replace clogged pipes. from your description, it's the
sink faucet.

Good luck,
Dave M.

 

    I would not be surprised if one of the valves (under the sink or on the
sink) are defective and not really opening when you turn the control.  Try
disassembling them and see what happens.  Be sure to turn off the main and
release the pressure first.

Three possibilities: faucet, shutoff valve, pipes.

If the faucet and its valves are old, this is a possibility.

The little disc valves that are commonly used for sink shutoffs have
an annoying tendency to clog, jam, and break in hard water. I always
replace these with ball valves just on general principles.

The pipes are the least likely, but if you get no water to the shutoff
valve, suspect them anyway.

You will need a partner at hand to control the main shutoff, so you
don't have to run for it if you get a valve stuck open.

Then start by closing the shutoff valves, disconnecting the sink
supply lines, and opening each shutoff valve briefly to see if you get
good flow there. If so, it's the faucet; repair or replace it. If not,
replace the shutoffs. Use ball-joint shutoff valves; they'll last many
times longer and cost just a couple dollars more.

If replacing the shutoffs doesn't give you free flow, you have a
clogged pipe. Unless you're handy with pipe work, it's time to call
the plumber.

 i start at the screen in the spout of the faucet.
then just use common sense and work your way
backwards untill you have good flow of water.
unless you have galv. pipes for water they prob fine.
like others say, shut-off valve likely point of clog if
it is not in the faucet itself..

Ill admit I have wasted time before looking at pipes
and valves when the problem was in the spout of
the faucet.
