Are there any disadvantages of the Point-of-Entry (POE) system compared to the Point-of-Use (POU) system
The POE system has a higher initial cost but the New Jersey Housing and Mortgage Finance Agency offer no interest loans through its Potable Water Program to cover the cost of installation.
The POE system requires approximately 6 square feet of floor space in the basement, though it does not take up any space under the kitchen sink like a POU system would.
