FREQUENTLY ASKED QUESTIONS ABOUT PLUMBING SERVICES IN CANBERRA
How do you install plumbing in a new house?
Here are the steps when installing plumbing in a new house:
#1. Rough-in phase
The rough-in phase involves laying the primary lines without making the final connections. This is done when the framing is done, but before hanging the drywall. Next, installation of main drains is done, and these are connected to the vertical drain pipe, called the stack, that other drain pipes feed into. The sinks and bathtubs’ rough-in drain fittings are also installed, and the toilet flanges and water supply pipes.
#2. Setting and connecting plumbing fixtures
Showers and bathtubs are too large to set once the framing of walls and doorways is complete. Thus, these are set before the framing of walls. All fixtures are set and connected to the supply and drainage systems.
#3. Installing the water supply system
The mainline serves as a passageway of the pressurized water supply. Therefore, the line must be set below the frost line, the depth where the freezing of groundwater occurs, to prevent the line’s freezing and damaging the pipes.
#4. Installing the drainage system
This involves installing the central vent and soil stack, and the waste drains that connect to it.
Why is cast iron plumbing bad?
Cast iron pipes are durable, but these are prone to corrosion and can develop rust, slowing water drainage. Cast iron is not dangerous. However, joints and connections contain lead, which can affect health when consumed. It is not a big concern since these pipes are not meant for drinking water. However, only qualified plumbers should perform repairs.
How long does PVC plumbing last?
PVC or polyvinyl chloride piping lasts from 25 to 40 years. Technological advancements, however, can extend its longevity for up to 70 years or more. PVC is resistant to shock, chemical rotting, weathering, corrosion, and abrasion.
Should I replace copper pipes?
You do not need to replace copper pipes that are in excellent condition. However, if the pipes show damage or deterioration, or if you have acidic water, then you should replace copper piping. Leaching happens when highly acidic water comes into contact with water and deposits a blue-green scale on tubs, sinks, or other plumbing fixtures. This does not only affect metal finishes; it also produces a bitter metallic taste.
