I've got six tanks on a stand, three on each side, one above the other and a sump in the centre below.
Each of the top tanks are 140ltrs and the sump 200ltrs.
The highest point of the stand is 2100mm. The piping for the return is 25mm,there are 3 off 90 elbows on the return line and a T right at the top to fill the tanks left and right side.
Each tank has a overflow pipe of 50mm with two way soil vent valve and reduced to 25mm into the next tank.
I tried a 3000ltr/hr return but the pump can't do the job. Should i make the return line smaller or go for a bigger pump.
