Water pipelines and distribution systems are subjected to surges almost daily, which. over time can cause damage to equipment and possible contamination. Surges are caused by. sudden changes in fluid velocity and can be as minor as a few psi to five times the static. pressure. The causes and effects of these surges in pumping systems will be discussed along. with equipment designed to prevent and dissipate surges. Only with the knowledge of all of the.
If a boat is sitting in water, water will leak in through any open cracks or holes. It works the same way with a basement. Hydrostatic pressure can push water through hairline cracks. Symptoms of this are water coming up through cracks in the basement concrete floor or water coming in at multiple locations.If you have an older house within town and the house has a basement with no sump pump, it is likely the perimeter foundation drain system connects directly into the city storm sewer system.f the water is coming up through floor drains or sink drains in the basement, then the problem is often water backing up from the municipal sanitary sewer system.
