Filtration is an absolutely vital part of any rainwater harvesting system. A lot of people aren’t aware how much grit is in rain water which can be damaging to equipment further down the line. A common problem people come across in irrigation systems running is that their solenoid valves stay on when they should turn off. This is nearly always caused by debris from insufficient filtration.
