my underground rain water tank is full, some debris on the top of the filter. this system is 5 years old, it was working fine until last september. now i can see, my onga switch indicating blinking green light for the rainwater tank but indicating green light for the mains section through out. all the devices attached to (washing m/c, toilet cistern/s) this system are working properly through main water.
