What causes air in water pipes?
I've already posted this, but I screwed up the Subject line. My
husband passed away recently and my brain is only on half power. Also, he used to take care of these kind of issues. Sorry about the multiple postings Question: I noticed that within the past month or so I have a lot of air when I turn on the hot water. As the water gets warmer the air gets worse. Since it's only the hot water I assume it's a problem in my house, but just to be sure I checked with my neighbors and the do not have any problems. We have town water. What could be causing this? The air comes out in strong bursts sometimes and it makes the pipes vibrate. thanks. Jane |

Air in pipes is common after work is done, but I've never seen it last more than a couple of days & only a couple of minutes if you go around and run everything. |

But, it could still be either maladjusted or malfunctioning and hotter water will cause more air out of solution plus perhaps more nucleate (localized) boiling on the heater (assuming electric) element(s)... So agree first question is "is it hotter than normal?" -- |

I am sorry for your loss and I see that you have received some good
advice. I will only add one thing. You have been trouble shooting this thing very well and you provided all the information that most people would not have included allowing someone to give you some answer. |

Wild guess: You have a defective thermostat on the water heater (or it's set way too high) causing the water to boil. It is extremely unlikely that the pressure would build sufficiently to rupture the tank, but it's not impossible. You'd have to have TWO things wrong: the bad thermostat AND a defective pressure relief valve. Still... Another clue supporting this theory is the temperature of the water. If it is REALLY hot - like steaming - the symptom lies with the water heater's thermostat (probably). It IS possible the thermostat's temperature setting got bumped when someone tried to store something next to it. Try turning it down. Alternatively, if you're on a well, it could be pumping air into the system - Nah, never mind, if that were the case you'd be getting air in the cold water line also. No, the water is not hotter than usual. In fact I was thinking of asking them to set the temp higher when they come. Also, it is not well water. I use Town water. |

(...) Could be cavitation. Any valves connecting water to your heater should be 'full on'. That is to say, the handle(s) should be turned counterclockwise till it stops. Here, a homeowner has turned off the 'inlet' and 'outlet' valves before disconnecting the water supply. http://www.waterheaterinstallation.i...d-top-crop.jpg Beware that the top of the heater will be HOT so use caution and think about the consequences of an involuntary flinch. Test first with the back of your hand and please stay clear of the exhaust stack poking up from the middle of the heater. --Winston Let me correct myself. The photo shows control valves for a parallel water heater, not the valves I was indicating. Still, the principal is the same. A restriction in the inlet side of your water heater could cause creation of air bubbles, so any valve(s) providing water to or from the heater must be fully open, to minimize this cavitation. --Winston |

Water tanks have anodes to keep them from rusting. Anodes produce bubbles of hydrogen and oxygen. It happens faster with soft water. Some anodes are designed to slow the bubbling. I'll bet you aren't using as much hot water lately. That gives the gas more time to accumulate. Excellent diagnosis! You could probably test this by holding a match under the faucet. No, wait... |

Actually I've had some air in the cold water pipes too. That's been going on for over a year and doesn't seem to happen in the winter. Maybe it is from the main inlet, although my neighbor across the street doesn't have this problem. The plumber is coming next week. thanks again. |

Does your hot water look milky? My hot water supplies four sinks, a washer, and a shower. One day when I drew some hot water in a glass at the sink in the main bathroom, tiny gas bubbles made it look white. The water slowly cleared as it sat in the glass. I tried it again. Still white. I removed the aerator. Still white. After I drew more than a quart, it still wasn't clear. It was clear the next day and ever since. I wonder if the white appearance came from tiny bubbles of hydrogen and oxygen that had been dissolved in the water until I reduced pressure by opening the tap. I don't know why the water with the dissolved gases would have collected in the pipe to that tap. If more gas had accumulated in the water, perhaps it would have sputtered from the tap. I wonder why the water was cloudy that day but not before or since. Could something unusual in the town water that day have increased gassing in my water heater anode? |

It's 60' in the air of course but the sucker is HUGE. The pole on which it stands is round, concrete, and about 30' in diameter.

However, there are relay stations and booster pumps. In the district I am in, they use towers and booster pumps. The air can be caused by the cavitaion of the booster pump. I am at the end of a water main and I get air everytime the electric goes out and sometimes when it don't. I was just adding my $.02. The tower would make a great house if you didnt' mind all the damn stairs. Hank ~~~too old for that many stairs |

Suppose the incoming water is saturated with dissolved air. If it stands in cold-water pipes in the house that are warmer than the source, bubbles will form. Even more will form in the water heater. Households using more water might not notice it. I imagine water wouldn't have that much air unless it was dissolved under pressure. Could a municipal water system dissolve air in water under pressure? Another possibility is that the dissolved gas was generated in the pipes as a product of water purification. Could that be? |

Hank Yes there is air in both hot and cold BUT, there is only a little burst of air when I first turn on the cold water, before the water comes out and only in the kitchen. This has been happening for more than a year, and for some reason doesn't happen at all in the winter. There is lots of air in the hot water, the worst being once the water has run a while. No matter how long the water runs there are still bursts of air and it happens everywhere the hot water is used. |

Also, it is not well water. I use Town water.- Air in water lines that are on city water can be a common occurence, especially if you are at the end of the main line. When the pumps loose power due to an electrical outage, or other reason, air is produced thru what is called "cavitation" in the pumps volute. If this is the case, there is not much you can due about it, other than contacting your water company and see if they can (or are willing) to either reduce the pressure slightly or take other measures. They way want to know about your problem in order to maximize their delivery and avoid other problems. Anyway, check with them before you call a plumber. Hank ~~~~ Sorry about your loss. I live in a condo. There are four other units in my building. None of them are having problems. This isn't just a little air, it's enough to make the pipes rattle. It you get it at hot and cold taps, it sounds as if air is getting into municipal pipe. It can happen when hydrants are flushed or pipes are repaired. I don't know how it would get in every day. Perhaps bubbles smaller than peas travel along the municipal pipe, and the slope guides them to your condo and not others. When your cold tap in the kitchen is off, just enough air collects to make a small pop when you turn it on. When the water is flowing, the bubbles are too small to pop. In the water heater, the little bubbles would rise to the top and enter the outlet as a larger bubble. That would explain why you hear big pops while the hot water flows. If the problem starts with little bubbles in the municipal main, I don't know what would cause those bubbles. |

Remember that water has some air dissolved in it. How much can
be dissolved depends on the temperature and pressure of the water. |
