The On the Go has been regarded as one of the best RV water softener systems by many reviewers and customers worldwide.But you might be wondering how this little machine works .

Lets jump straight into it !

As hard water flows through the salt/potassium rinsed resin bed in the RV water softener, water hardening ions (calcium and magnesium) are trapped by the resin out of the water.

In return, softening ions (sodium/potassium) on the resin bed are released into the water. This process is called ion exchange.

Back-washing is done once in a month or 2 to flush out sediments and contaminants that would have accumulated on the resin bed .

Back-washing is a process of running water in reverse direction through the outlet and water comes out via the inlet. Back-washing process takes around 15 minutes to complete. The overall goal of back-flushing is to maintain the optimal performance of the unit.

Regeneration is a process of rinsing the resin bed with brine or salt solution .Salt is poured into the tank through the large mouth on top of the unit. Magnesium and calcium which would have accumulated on the resin bed are washed out of the unit via a drain .

The resin bed is also rinsed with salty water so that ion exchange can continue optimally. In most cases only 2 canisters of table salt or crushed potassium are used for this process.
