Is protective plumbing an effective means of preventing a basement flood?
Protective plumbing helps to protect against sewer backups resulting from sewer surcharges and main sewer blockages. Sewer mains can’t always handle the extra water flow (sewer surcharge) caused by spring run-off and heavy rains. When these events occur suddenly, backflow valves help to prevent the entry of wastewater into the residential sewer lateral. Protective plumbing offers little protection against flooding that results from the damage or blockage of a sewer lateral on the homeowner’s property where the wastewater flow from the residence is the source of the flooding.
