The SNH Air valve for sea water protects sewerage pipework by evacuating the air which is trapped at high points. Using this valve makes it possible to make savings when laying pipe networks.
In fact, when this air valve is used, the pipework can follow the relief of the land (as with drinking water) avoiding extra cost for laying pipes at great depths (reinforced trenches, lowering of ground Water level, ect.) Which are necessary for following a regular pipework profile.
