WHAT IS COMPLIANCE? replacement and repair of hot water system.
COMPLIANCE TABLES
Due to the numerous changes in compliance and the regulations / standards( as noted above) and more so due to the critical safety and hazard aspects of pressurised hot water storage vessel, much area of focus has been place on the hot water storage heater and the relevant standards and regulations relating to the installation and more so the compliance to these standards and regulations.
As result of these changes, lack of understanding and in some cases misinterpretation or misguidance, a state of confusion and further lack of understanding has creeped into the industry sector.
To help mitigate against this the Institute of Plumbing of South Africa in association with the Plumbing Industry Registration Board has a set of Compliance Tables. These Compliance Tables are an industry guideline, and denotes the critical requirements that must be undertaken by the plumber when the installation, maintenance, replacement and repair of a fixed electrical hot water storage water heater is done, to meet compliance in terms of the regulations and standards.
FOR EASE OF USE THE COMPLIANCE TABLES ARE SPLIT INTO:
1. |
Table A: Compliance Table for: The installation of a NEW fixed electric storage water heater( geyser) |
2. |
Table B: Compliance Table for: The REPLACEMENT of fixed electric storage water heater( geyser) |
3. |
Table C: Compliance Table for: The REPAIRS AND MAINTENANCE of fixed electric storage water heater( geyser) |
It is noted that each respective compliance table will give guidance to the PIRB Auditors when an audit is undertaken for any installation, maintenance, replacement and repair of a fixed electrical hot water storage water heater. It is further noted that if the critical compliance is not meet on any of the installation, maintenance, replacement and repair of a fixed electrical hot water storage water heater the respective licensed plumber will be issued a PIRB rectification notice.
* This document is to be used in conjunction with IOPSA notice of non-compliance and SANS 10254 & 10252 part 1 & 2
TABLE A: Compliance Table for: The installation of a NEW fixed electric storage water heater( geyser) The following table denotes the critical areas of compliance that must be undertaken by a plumber when a new installation is undertaken of a fixed electric storage water heater( geyser). Item Regulation Areas of Compliance 1 SANS 10252-Part 1 and SANS 10254
All NEW fixed electrical storage water heater( geyser) installations must comply with all requirements SANS 10252-1 and SANS 10254
A“ New” installation is defined as:- where any fixed electrical storage water heater( geyser) that is not being replaced;- where any fixed electric storage water heating( geyser) installation that forms part of a) a newly constructed dwelling and or building b) an existing dwelling and or building where an additional fixed electrical storage water heating( geyser) is installed
TABLE B: |
Compliance Table for: The REPLACEMENT of fixed electric storage water heater( geyser) |
The following table denotes the critical areas of compliance that must be undertaken by a plumber when a replacement is undertaken of an existing fixed electric storage |
water heater( geyser). |
Item |

1 SANS 10254 & 181
TEMPERATURE AND PRESSURE VALVE |
1) |
A Temperature and Pressure Valve must be installed. |
2) |
The Temperature and Pressure Valve shall have the same pressure rating as other valves used in the system. |
3) |
The pressure rating of the Temperature and Pressure Valve may be less than the rated pressure of the storage water heater but shall never exceed it. |
4) |
The discharge pipes from the Temperature and Pressure Valve shall |
a) |
never be joined together with other discharge pipes, |
b) led to a discharge point which is visible outside the building and in a position where the discharge from the pipe will not cause a nuisance and cannot become blocked,
c) |
be installed in a manner that will obviate the development of water traps which could prevent the free return of air into the system, |
d) |
sized not less than the size of the outlet of the valve for which the pipe is intended, |
e) |
Always be of metal and inclined downwards away from the valve. |
