• Do you have a water softener?
• If so, does it use sodium or potassium chloride? You will need to switch to potassium or un-softened water in order to send greywater into the garden and have it not damage the soil and plants.
• Is your home on a raised foundation (crawlspace) or a slab?
Greywater (or graywater) is any water that has been used in a home except toilet water, which is called black water. This includes water that drains from washing machines, sinks, showers and tubs. Kitchen sink and dishwasher water is sometimes called dark grey water, as it may contain grease and food particles, which can cause clogging and slow infiltration into the soil.
