pH Correction.

What is pH?

pH is a measure of how acidic/basic water is.

The pH of pure water is 7.

The pH of your water should be between 6.5 – 9.5.


How do I know if my water is acidic?

We always recommend having a comprehensive water test carried out.

Water with low pH can be indicated in the following ways:

  • Metallic or bitter taste to water.
  • Hair Colour issues (Light coloured hair can turn green).
  • Blue-Green stains on sinks, baths, toilets and showers.
  • Problems with pipework and fittings/fixtures (leaks, pinholes, corrosion)


How is the problem corrected?

Raising the pH to 7 or above reduces these problems and makes the water taste better..

Dawson Water can raise the pH of water by installing a pH correction filter.

These units work by passing the water through a vessel containing slow dissolving calcium carbonate and magnesium oxide media.

These minerals slowly dissolve, ‘re-mineralising’ the water and naturally raising the pH.

Dawson Water have two types of filter setups available for pH correction.

The water can be passed through the media using either an in/out flow head or through an automatic Back-washing filter head.

The Back-washing valve has the benefit of disturbing, settling and rinsing the media every few days.

This helps to remove any iron, manganese or debris which may build up within the unit. It also helps to prevent funneling.

Funneling happens when water finds the easiest path through the media. In doing so the water travels through too quickly to react with the media.



How much maintenance is involved?

Because the media in a pH filter dissolves into the water to correct pH, it will eventually need to be replaced.

To avoid running out of media, we recommend a system service and top up once every 12 months.

Dawson Water provide a full maintenance service to all well water systems including well pumps and controls

which are often neglected.
