Salt Chlorinator Saltwater Pool Maintenance – What To Do

Watermaid Salt Chlorinator

The Watermaid salt chlorinator system drastically reduces the maintenance required for a standard pool. The weekly routine of shocking the pool with high doses of liquid or granular chlorine will no longer be required. The Thursday panic visit to the pool store to get the pool ready for the weekend will be a thing of the past.

In an ordinary pool, chlorine combines with waste material in the pool, which is typically a nitrogen, or ammonia based compound. The normal cycle sees the chlorine combine to form mono,di and tri chloramines. These combined chloramines are the compounds usually associated with community pools and really dirty private pools. They have a strong “chlorine” smell that burns eyes, irritates skin and leaves you with the typical chlorine smell after you swim. The only way to rid the pool of this locked up chlorine is to “super chlorinate” or “ shock” the pool on a routine schedule, which is usually every week.

In a Watermaid pool, the chlorine that is generated doesn’t have the chance to build to the more complex molecule before it is passed back through the cell where the molecule is broken apart freeing up the chlorine and driving off the nitrogen or ammonia compound.

Salt Water Pool Maintenance Cost

The average pool in Canada costs around $400.00 to maintain for the season. With a Watermaid system, you can expect to pay $70.00 to $80.00 per year for chemicals AND ELECTRICITY to run the unit.

Without the combined chlorine and with a salt level that closely matches our body chemistry, the system provides the clean, cost effective and odour- free comfort that our customers have come to expect from a Watermaid salt chlorinator.

Saltwater Pool Maintenance and Inspection Routine

To ensure the Watermaid Unit functions and operates efficiently for many years, it is necessary to inspect and service the Watermaid Unit occasionally.

The list below shows the most common tasks required to ensure trouble free operation and adequate chlorine production from the Watermaid Unit.

  • Visually look at your swimming pool. If it is Clean, Clear and Sparkling, it means there has been sufficient filtration, and chlorination from the day before and that your water balance is OK.
  • On the front panel of the power pack, select the + button until the green LED is at the 100% position.  When you release the button, the unit will try to power to this selected output position.

If the salt level is correct (6000 parts per million) and the water is a reasonable swimming temperature ( about 80- degree F or above) the power supply will be able to drive the cell to its full production current and all of the lights on the front of the power supply will light up to the 100% position.  Colder water or lower thant optimal salt levels will reduce current flow to the cell and the lights will not reach the 100% position.  As an example, with spring start up when the water is usually around 50 degrees F, it is normal for the lights to only go up to the 50% position when 100% is selected on the power supply.

Keep in mind that the LED lights on the front of the power pack are the same as a digital  ammeter.  IF the salt and temperature are right, the cell will draw 30 amps for older units and 25 amps for newer units.  This full output is shown on the power supply with all of the lights up to 100%.

If the lights go to 100% during this test, the salt level is correct.  If the water is a reasonable temperature for swimming and the lights do not go up to 100%, this is typically an indication that the salt level is lower than optimal.  Add salt and wait 24 hours for it to dissolve and stur up in the pool.  When the lights reach 100%, the salt level is correct and you can then select the desired output to maintain chlorine residual in your pool.

Please Note: as cells age and wear out, production and current draw will reduce.  If you suspect that the cell may be getting old, it is recommended that you have the salt level tested with a proper digital salt tester to ensure that the proper salt level is maintained in your pool

Please also note that every hour the unit performs a self clean for 5 to 10 minutes. At this time, the blue self clean light will be flashing.

  • Check the salt level in the pool once a month using this procedure. More often if your area has experienced heavy rainfall or you have lost a large quantity of water from the pool and you have had to refill.


  • Clean the cell to ensure calcium deposits do not result in reduced water flow.  The loss of proper water flow in the cell will allow heat to build up to the point where the clear cell will become milky.  Further restriction can result in cell warping and destruction of the cell.  Damage from lack of cleaning is not covered by warranty.


  • These are the basic checks to perform when using the Watermaid Salt Chlorination System.
