Hi G,

Please describe your pump system. Source of water, size of pump, how you determined you have low pressure, number and size of plants or size of plant bed, system to get water to plants and age of pump. It can be a faulty pump or clogged lines or almost anything. You could try hooking up to another source of water with good pressure temporarily and if that works it is the pump. If it is the pump that could be clogging of a strainer or a filter or failure of a pressure regulator or backflow device or could be just age. If the new source doesn't work, it is the watering system that needs to be cleaned and checked for grit and growth of algae or anything that could slow the flow down. If you have patience a solution or probably many helpful solutions will be suggested. Aloha.
