What was supposed to be a quality sump pump
The problem in the home in Salisbury, MD is that the sump pump isn't enough to handle every job. Most of the time you will need to install a good liner and drainage pipe system to complete the solution. It's a little like thinking you can travel cross country with a car that only has an engine, no seats, or tires, or doors, etc. Each wet crawlspace needs a whole system of components to keep the crawl space dry and clean - all the time!
Basement Sump Pump
This is a common sight in a basement. An old clay sump liner and a pump that looks pretty cramped in that tiny hole. Whats worse is that they usually only go down into the ground about one foot. A proper sump pump should be much deeper and wider, this allows for more pressure to be released. It also keeps the pump from running a lot which increases the power bills and shortens the life of the pump.
