The kinetic energy of the mass of exhaust gas carries it along the exhaust pipe, and causes a pressure build up ahead of the mass of gas and a partial vacuum behind it. This principle is used in a tuned exhaust system.
Culligan - $2352 ($2053 w/o R/O unit) Culligan Gold Series (10), Good Water Machine. If I were to look at price only, I would go with either the cheaper Ecowater system w/R/O at $2698 or the Culligan system. At almost $4k, the Kinetico system seems greatly over priced.

The water softener is the flagship product of the modern water treatment industry. Traditional water treatment âdealershipsâ have been built around the water softener for decades. The softener is commonly said to have been introduced in 1903, although the details of its origin are sketchy. Here is the Culligan version of the origin of the softener, from Culliganâs website: Emmett Joseph Culligan grew up in a farming background in the hard water areas of South Dakota, Iowa and Minnesota. He was well aware of the difference between hard well water and the soft rain water most families collected in cisterns.
