Water noise through pipes
 
Hi, when I am watering on the grass/garden manually with hose pipe, all the water pipe lines (passing through attic) making lot of sound..
But this does not happen when we bath or using any faucets.

Any specific reason for this ? Is it good or bad ? Is it because we try to spary the water on the garden ? I did not notice this before. Happpening for the last couple of weeks.

Any insight into this ?

What kind of sound is it?

As if water is going through the pipe with velocity.. and also little vibration effect.

What kind of water system are you on?

Galvanized pipes . Did this answer your question ?

City water.

Check your pressure. An increase in pressure could be the culprit. Increased pressure, increased velocity, increased noise coming from the pipes... ?

Just a guess. Check into it.

Thank you. But I don't think I have a way to know this. Because, I have not measured the pressure before .. to compare the current pressure.

You will know if the pressure is high vs normal. Pick up a gauge and check it.

Ok. I will buy the gauge and check it out.

Turbulence caused by a partial obstruction or bad solder joint?
Cavitation? [may cause premature pipe failure].

why only when watering outside?

Get you a bucket of any size. Go outside with this bucket, and use the hose as you do to make the noise, then turn the hose into the bucket. Mark the time it takes to fill the bucket. Go inside, using the same bucket, place it under your bath faucet and turn on the cold water - -wide open. Mark the time it takes to fill the bucket at that point. I'm betting the bucket gets filled sooner with the outside faucet/hose. That means more volume coming through the outside hose bibb vs. the bath faucet. Therefore: the volume of water/velocity of water is greater with the outside faucet, which gives you the noise of water rushing through pipes. Just my 2 worth, David
