Can I use this to fill a large water tank (2500 gallons)? I'm currently on a well that feeds my 2500 gallon tank.

Hi R. Petersen, Thank you for your question. As long it is a holding tank and not a pressurized tank it will be okay. It might take a week for the tank to fill to maximum capacity as it is a 500 gallon per day system. Please do keep in mind the 500 gallon per day is based on if the water condition is perfect so the actually number might vary slightly due to water pressure, temperature, ppm, and contaminant levels. Thanks!Helen

For whole house usage, which tank and pump do you recommend?

Hi, This system is not normally recommended to be used in a whole house application. We do have customers who have used this system in this application but we do not recommend this as the system was designed to be used as a commercial RO system for small businesses. Thank you, iSpring Water Systems LLC

How do I back-flush the RO membrane as the manual recommends but does not say how to do it?

Hi A customer, Thank you for your question. This system is now designed to flush automatically so you no longer need to manual flush it. Thanks, iSpring Water Systems
