About a month or so ago I noticed that sometimes when I turn on the
water in the kitchen I get that popping noise that indicates air in
the pipes. Happens for both hot and cold. Doesn't happen anywhere
else in the house (two bathrooms, washing machine).
What would cause that?
I know zero about plumbing. I don't know if I need to call someone or
can I ignore it?
It doesn't sound like "air in the pipes," unless this popping noise
is accompanied with the water sort of spitting out of the spout. It
sounds more like a loose part in the faucet, or maybe the hot pipes
expanding as fresh, hot water runs through them to the kitchen. It's
probably safe to ignore it till other symptoms appear.
It's definitely sounds like air. Makes the same sound I hear when we
turn the main water back on after it's been shut off for a while.
One more thing - we have a bathroom that backs up to the kitchen.
They share some of the pipes. The bathroom faucets do not make this
noise so it's somewhere in the kitchen pipes only. I don't see any
leaks under the sink. As for what's going on in the wall, who knows.
It is not air. It is the faucet. It only sounds like air. Air
can't get in from a leak in the water pipe. If there's a leak, like
you suspect, then water would be squirting out of the pipe, and not
air entering the pipe. It might be the sprayer, or diverter, or some
other loose or worn part inside the faucet or shutoff valve
underneath. You can live with it (which is OK if it's not too
irritating), or wait till it gets worse, or call a plumber.
