I'm installing a 500 gallon water tank next to an existing water tank... The existing tank holds 300 gallons and is fed by well water. This tank has a float shut off and a pump that pumps into a pressure tank and then the house. We will connect at the bottom w/ 2" PVC.
I've read that the two tanks need to be set at the same heights. Does this mean that the new 500 gallon tank will only store 300 gallons since the existing tank will shut off at that point via the float switch?
Can I raise the level of the 300 gallon tank so that it is higher than the 500 gal tank (I was thinking the 500 would store more water but now realizing that the water in this tank wont flow back to the 300). Thank you!
