Remember the scenes in the movies where fish and small animals end up in public sewers after getting trapped in the kitchen sink or toilet bowl? These exciting scenes in the movies give us a little knowledge about plumbing systems.
We may not have an ounce of concern for this aspect of our property, but aren’t you curious why wastewater in our homes does not mix with your water supply? Haven’t you ever wondered if this could be possible? Or are you certain that no rainwater enters your kitchen sink pipe? If these questions start to get you thinking, then you’re at the right place.
In this article, we’ll give you some pointers about Singaporean government’s regulations as regards the construction and structure of home plumbing systems. No less than the Public Utilities Board or PUB has published these regulations and your plumber must follow them if you don’t want to end up with one who fires a flare while in the job.
Discharge pipes should be properly located
We all know that every household discharges waste water everyday. The question is, what is the structure of our plumbing pipes that we do not smell any trace of this wastewater inside our house? Under normal circumstances, there shouldn’t be any trace. But if there is, you have to call a reliable plumber to help you address this issue.
To answer that question, discharge pipes where wastewater passes should not be and are not located in areas where it can cause health hazards. This is one of the regulations by the PUB. These pipes cannot be located near any water storage or water supply pipes or fittings. They must also not be in places such as above living rooms, kitchens, bedrooms, and dining areas to avoid any nuisance.
Soil sanitary appliance location
PUB also requires that soil sanitary appliance where excretions and waste substances are discharged should be away from and not connected to the water supply pipes or to any other network in our plumbing system except the flush valve or cistern. The last two plumbing fittings are directly connected to the toilet bowl so they should also form part of the soil sanitary appliance. With this location of the soil sanitary appliance, potable water will not be contaminated.
Installation of anti-mosquito devices
We know that mosquitoes thrive in water. Our plumbing system where water supply continually flows day in and day out should therefore be protected. This is done by installing anti-mosquito devices on the plumbing pipes and fittings to make sure that mosquitoes cannot enter the system.
Air and water tightness test
Leaks, contamination, and improper water pressure are the worst enemies of plumbing systems. Therefore, plumbing systems should be protected from these factors at the stage of construction. This is done by PUB by requiring construction and plumbing contractors to conduct air and water tightness test when setting up plumbing systems. These tests will ensure that air will not interfere with the water pressure inside the system and no contaminated water can seep through or flow through the pipes.
These are only a few of the plumbing regulations in Singapore that were put in place to ensure the integrity of home and commercial water supply all over the country.
