Every cistern shall be installed so that it is easily accessible for cleaning or repair. Where a cistern is installed inside a building and, due to limited headroom available, it is fixed with limited clearance from the ceiling or underside of the roof, a quickly detachable fitting must be used to enable it to be easily removed for cleansing and repair. 10. Safe access shall be provided to all cisterns by means of a secure permanent ladder or readily available portable ladder.(L.N. 252 of 1977; L.N. 81 of 2017) Part 4 Hot Water Inside Services 1A.

If mixing valves, water blenders or other combination of fittings are used with a water heater, the cold water supply to those fittings must be drawn from the same source that supplies the water heater in order to provide a balanced pressure and to obviate the risk of scalding if the water supply at the source fails or is restricted for any reason. 5. A thermal storage type water heater, other than a water heater of the type specified in paragraph 2(b)(iv), must be provided with an individual expansion pipe at its highest point and the pipe must continuously rise without obstruction until it discharges to atmosphere above the cistern at a sufficient height to prevent a constant outflow of hot water from the water heater via the pipe. 6.
