Some of our competitors' prices don't include GST on their websites.

Pumps, Plumbing Filters and UV Water Purification

Our stainless steel, multi-stage pumps suit both small and large dwellings. The smaller pump provides adaquate water pressure for small to medium homes i.e. up to 6 taps running. In contrast, the larger pump is intended for large single or multi-level homes and can supply up to 12 taps. The pumps operate automatically. They work with a range of pressure tanks (or accumulators) to maintain constant pressure in your plumbing system.

Firstly, ultraviolet water purification is an effective method used to destroy bacteria in water. This is because UV penetrates and kills harmful pathogens. UV destroys illness-causing micro-organisms by attacking their genetic core (their DNA). Consequently, this method extremely efficient as it reduces their ability to reproduce. Disinfecting your water in your pipework with ultraviolet light is exceptionally simple, effective and above all, environmentally safe. UV systems destroy 99.99% of harmful microorganisms in your piping. You therefore do not need to add chemicals which change your water’s taste or odor.

Secondly, UV water purification is usually used with other forms of filtration such as reverse osmosis systems or carbon block filters. UV kills germs whereas filters remove particles and dirt from the water. For that reason, both filters and UV should be used together.

Finally, filters and UV purification systems work together as part of your plumbing system to deliver sparkling, germ free water. You can certainly trust Big Plumbing Supplies with ensuring that your potable water supply is both clean and healthy.
