PUB Regulations For Storage Water Heater in Singapore
PUB Submission Required For All Storage Water Heater Installation In Singapore
We will install the storage water heater according to PUB regulations together with PUB submission.

These valves are required for proper installations. This helps to prevent back flow of water which may cause contamination to the water supply.

We will install the drainage piping to ensure that the pressure relief water discharge is able to drain off properly.
What Will Happen If The Requirements Are Not Done?
CONTAMINATION
Water might get contaminated if the required valves are not installed.
