Bryanston Ext 11 is an extension of Sandton with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
