Water flows into your property at a constant pressure, arriving on command at your tap, shower or other fixtures. However, this constant pressure is reduced when a water main bursts or there is a high demand on your water system. With less pressure in your pipes, water may be drawn back into your main supply. This is known as backflow.
Without adequate backflow prevention there is a risk of contaminants entering your drinking water system. Whether these are chemicals, oil, bacteria or debris, they are definitely uninvited guests!
A backflow prevention device prevents the reverse flow of water from potentially polluted sources from passing into your home’s drinking water system. Think of it like your plumbing guardian angel.
