Hi not sure if it's a silly question but here goes. From my tap I'm getting a Reading of 53 on the tds into my di Coming out at 0 to my brush. But I've put a never di after the pump to make sure it comes out 100% 0. My question is because my 2ed di is not working as hard as the fist 1 will it last longer because it's not cleaning it as much or is it how much water goes throw it ? Thanks
