Clear answers before work begins.
What is the difference between a sewer backup and seepage?
A sewer backup involves reverse flow through the drainage system. Seepage typically enters through walls, floors, cracks or foundation drainage.
Can a backwater valve prevent every sewer backup?
No single device eliminates every risk. Suitability depends on the property plumbing and the source of the backup.
Should I use basement plumbing after a backup starts?
Avoid adding more wastewater to the system until the cause is understood, especially if sewage is already entering the basement.
