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!
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.
When you think of a sump pump, what do you imagine? Apparently a lot of people would think its a hole in the ground no bigger than a potted plant with a $30 hardware store pump attached to a length of garden hose. This may have been fine 30-40 years ago but the times have changed. We now know that you need a lot bigger hole and a sturdier pump if you want it to last.
