I purchased a pump automation unit (FAWLC-043-100) from RMG a few years ago and consider it an excellent product. A simple system consisting of a control unit, with sensors in the water sump and in the overhead tank.
Basically trouble free and when there were a couple of issues, the same was attended to by a very polite Mrs. Gandhi and equally polite and knowledgeable technicians.
Yes, should the there be a fault, there may be a bit of delay in obtaining the technician, but a date of visit is given and generally adhered to. This delay is not a matter of "life and death", and one just has to revert to manual mode till the fault is rectified.
