Question 1

Does a whole-house filter make the water safe to drink?

Accepted Answer

It takes out sediment, rust and chlorine, which protects the geyser, the appliances and the taste. It does not remove dissolved salts, nitrates or bacteria. For drinking water add the AquaShield at the kitchen tap; for a borehole or tank add the AquaClear UV after the filter.

Question 2

Will it drop my water pressure?

Accepted Answer

Three 20 inch Big Blue housings pass 2 720 litres an hour, more than a house uses with every tap open. With fresh cartridges the drop is about 0.2 bar. When it reaches 0.7 bar the cartridges are due.

Question 3

Where does it go?

Accepted Answer

On the main line where it enters the property, after the meter and the stopcock, on a wall or standing on its frame. Fit an isolation valve before it and, if you want to change cartridges without shutting the house, a bypass.

Question 4

How often are the cartridges changed?

Accepted Answer

Every six months on municipal water, three to six on a borehole. The three-stage set and the two-set box are in the replacement filters category.

Question 5

What about borehole, tank or rain water?

Accepted Answer

The AquaGuard handles the sediment and the taste; the UV steriliser after it deals with bacteria, viruses and cysts, and the combo puts both in one order with the adaptors that join them. Iron, manganese, hardness or a low pH need a media vessel ahead of it, sized from a water test.
