Plumbing making rumbling noise?

Ok, so my toilets were making banigng noises after the tank filled up so I thought I had water hammer so I drained the entire house and opened up all the faucets to let the air out and the noise is gone. I still have noise when I turn on my kitchen sink as well as my upstairs bathroom sink. Can anyone tell me how to get rid of this or what the problem is? The toilets no longer make the rumble, just the faucets.

  1. It is - almost for sure - a loose washer somewhere.  Either in both fixtures that are rattling, or in a common valve somewhere.

    I see it most often in toilet fill valves.

    BTW, if you're on city water (as opposed to a well) air is not likely to get in the line.  The incoming water is under pressure.  If there was an opening, water would go out rather than air getting in.


  2. You're pressure is to high you need a pressure reducing valve on your main water line or you're going to deal with alot of maintenance issues with your fixtures

  3. If you turn off the water slow at these faucets and no noise is heard you have a loose pipe in the wall somewhere and it is banging around. Over time the pipe could pull apart. washers loose in the angle stops can cause his problem too.

  4. make sure all your connections are taped so that air isn't getting into the lines every time you turn on the water.

  5. I'm no expert, but I'm pretty sure it's not ghosts. ;) Even though you drained the lines it still sounds like water hammer. You may have a leak somewhere. But it could also just be the layout of the pipework. I do landscaping and often have to work on irrigation systems (which I despise). Usually the result is a leak somewhere, but occasionally it turns out to be either pressure fluctuations or awkward line placement.

  6. There's just some air in your lines.  I would ask your neighbors first to see if they're getting any of the same thing.  Some city water systems are bad about getting air in supply lines to consumers, expecially after repair or maintenance when part of the infastructure is drained.  Also some wells (country use) will draw air into supply lines, be it from the surrounding rock, or a crack in a "negative pressure" section of the system.  If homes around yours are newer, there is a good chance they had slightly different plumbing codes when built, and will be less apt to have the same problems.  Some homes do have a water system high point vent in the attic, but those can be difficult to find (and use).  You can take a look, but they really don't bleed enough air to be effective.  One thing with faucets is to make sure both hot and water lines are vented.  There is a vent directly off of most water heaters, which will be a little more effective than just running the hot water.  Start by asking the neighbors, but it sounds like you have air in the lines and a little watter hammer, which isn't a huge issue.
