Poor follow up by the company with the complaints registered.Dont choose the sediment filter(automatic) as shown in the picture, if you dont have inverter. During the back wash(automatic cleaning), if the power goes off, your water tank will get empty as the valve will not close. Even their technicians has no idea about this. Better go for the manual back wash system.

Worst customer service at Thrissur, waiting for the fifth day for installation of a water purifier.
