P H Correction

In cases where the water is acidic a P H correction filter can be applied to bring the water to a safe standard.

How pH correction works

Treatment to increase pH usually involves passing water through a neutralising filter containing alkaline media such as limestone or magnesium oxide. You should get advice from an installer.

It’s important that the filter’s size, and the blend of media within it, is right for your water supply, otherwise the pH could be under, or over, corrected.

Installing a neutralising filter correctly depends on your individual circumstances, so it’s best to consult a specialist contractor.

Neutralising filters should generally be fitted after any other filtration, so that the media does not become clogged by debris.

Neutralising filters rely on alkaline media dissolving in the water to change the pH.

The media is gradually used up in the process, and will eventually need to be replaced.

It is important that the amount of media in the filter is regularly checked. This can be done by monitoring pH using a simple test, and seeing if there are any stains on fittings and sanitary ware.

If you do need to top up the media, make sure you use the right type. It is worth cleaning out the filter vessel from time to time and completely changing the media.
