Sewer Gas Corrosion
Sewer Gas Corrosion
(OP)
Have any of you experienced copper corrosion as a result of sewer gases? I have been made aware of a lift station installation that is about 1 to 2 months old that has had several (as in 5 or more) pump breakers "burn up" as I am told. One of the breakers was off and flashed over to ground. All of the exposed copper has a black coating on it.
I asked if the smell was like rotten eggs thinking that it was probably hydrogen sulfide gas, but can not get anyone that can tell me for sure. All they can tell me at this point is that the odor is unusually strong.
Seems to me that without some special treatment of the gas, explosion proof boxes/piping is the only answer.
Any thoughts?
Thanks

I don't think explosion-proof fittings are going to help much.

Do not rely on colour coding for cable identification. PVC insulation will all be a uniform shade of brown in a matter of months. The only thing which is likely to work under these conditions is ventilation. You need to get rid of the problem rather than try to live with it.
