Everytime i go away, when i connect the water up and run the cold tap to purge the air, pink water comes out of the tap for a few seconds. There is no inline filter in the system so does anyone know what could cause this..
A red or pink pigmented bacteria known as Serratia marcescens is thought to be the cause of the pink “stuff”. Serratia bacteria are common inhabitants of our environment and can be found in many places, including human and animal feces, dust, soil, and in surface waters. The bacteria will grow in any moist location where phosphorous containing materials or fatty substances accumulate. Sources of these substances include soap residues in bathing areas, feces in toilets, soap and food residues in pet water dishes. Many times, the pinkish film appears during and after new construction or remodeling activities. Others have indicated the pink “stuff” occurs during a time of year that their windows are open for the majority of the day.
These airborne bacteria can come from any number of naturally occurring sources, and the condition can be
further aggravated if customers remove the chlorine from their water by way of an activated carbon filter. Serratia can also grow in tap water in locations such as toilets in guest bathrooms where the water is left standing long enough for the chlorine residual disinfectant to dissipate. Serratia will not survive in chlorinated
drinking water.
Serratia marsescens is not known to cause any waterborne diseases. Members of the Serratia genus were once known as harmless organisms that produced a characteristic red pigment. More recently, Serratia marcescens has been found to be pathogenic to some people, having been identified as a cause of urinary tract infections, wound infections, and pneumonia in hospital environments.
Once established, the organism usually cannot be eliminated entirely. However, periodic and thorough cleaning of the surfaces where the pink slime occurs, followed by disinfection with chlorine bleach appear to be the best way to control it.
I suggest you use puriclean throughout the system and including your aquaroll too you may have to do this several times a year to clear it though
Might also be worth getting a drain down kit. I use ours after every trip unless we are going away the following weekend. It's always suprising how much water comes out the system after it has been drained normally.
