Effervescence,
Air, or Dissolved Gasses in Water
There
can be many causes for dissolved air or gasses in water.
Some of the more common causes on city water systems are:
- Cross
connections in public water supplies
- Shutdown
and restarting of main distribution systems
- Overheating
of hot water systems
- Rapid
temperature changes in water
- Leaking
pump glands or leaks in water supply lines
- Recent
plumbing work done on premises.
Some
of the more common causes on private wells and small community water
systems are:
- Naturally
occurring methane gas
- Naturally
occurring carbon dioxide
- Overheating
of hot water systems
- Hydrogen
sulfide gas, from decaying organic matter
- Hydrogen
sulfide gas, formed in water heaters by iron or sulfate reducing
bacteria.
- Hydrogen
sulfide gas, formed in cold or hot water iron piping systems.
- Zinc
reaction in new galvanized piping
- Recent
plumbing work done on residence or building.
For
one time air-in-water events, the usual remedy is to contact your water
utility, and flush the plumbing and fixtures. For private systems, solutions
vary widely depending on the problem and application. In many cases,
venting the water in a holding tank accomplishes the de-gassing, but
in some cases, the water must be disinfected, or more extreme de-gassing
methods must be employed.
If you are on
a private water system, such as a well, and you wish our technical staff
to quote you a solution, it is important to supply us with an accurate
water analysis. You should also fill out an online
technical request form so we can better assist you in recommending
a solution.
