| V Englisch (en) | In water treatment systems, piping and hoses are required for the non-potable water as well as the aeration (blowers) supply. Many regulations governing reuse and non-potable water require that the piping supplying this water be indicated as such using either colours (purple in the case of Australia and California) or labels or both. *Experience has shown that blower hoses, suction hoses for distribution pumps and filtrate hoses are best installed using EPDM material piping. *The non-potable or reuse piping from the distribution pumps to the connected fixtures is recommended as pressure-resistant plastic or if desired, copper piping. *Do not use copper piping in the storage tank because it oxidizes even at low concentrations of hydrogen sulphide (foul odour) in combination with humidity. *All PVC hoses, as well as those chemically resistant, are eventually bleached due to contact with water. The softening agents serve as an ideal breeding ground for bacteria. Odours are also possible. |
