Alva geysers defective

These geysers did not work from day 1 and the geysers do not work in the Eastern Cape and probably majority of the other provinces due to municipal water pressure being erratic. The management of Alva / Stingray sent a technician out but in the end I had to purchase new Kexin geysers. The management of Alva / Stingray were not willing to reimburse any of the amount that i paid in purchasing 3 of their geysers. Very expensive mistake. Do not purchase Alva geysers. Rather spend your money on a decent brand like Kexin.
