The Boston Plumber’s Guide On How To Plumb A House

how-to-plumb-a-houseThe plumbing system works on the principle of supplying clean water and getting sewage out of the property. It is made up of a complex network of water supply pipes and drainage lines. And while there are plumbing jobs that you can do on your own such as replacing faucets, changing shower heads or unclogging sink drains, laying out the entire plumbing system should be handled by professionals. If you want to learn valuable information about plumbing installations, read on and we’ll share facts that you might want to know.

The Installation Plan

The installation should begin with the sewer system. Concrete foundation will be poured; the framing will be completed and then rough-in plumbing phase will ensue. This will be done alongside the duct and wiring installation. Afterward, the drywall will be hung. The main drain will be laid out and hooked to the stack, too. Drain fittings will be installed for the tubs and the sinks together with the installation of the water supply pipes and the toilet flanges. Finally, the small fixtures will be installed, too.

Plumbing Fixtures

Shower units and bathtubs are quite challenging to set when the doorways and walls are set. So they are usually installed before the framing. They will be covered to keep them from getting scratched during the construction. Toilets and sinks, on the other hand, will be installed after the flooring and walls are laid out.

The Clean Water Supply Lines

There will be a main plumbing supply line that will be hooked to the house. It will be split into two branches: one will be the supply line for the cold water and the other one will be hooked to the hot water heater. The hot water heater will also be connected to hot and cold water supply lines. Also remember that most fixtures have individual valves that will be used to allow or stop the water supply. This way, the main water shutoff won’t have to be used.

Drainage Pipes

Drainage pipes are connected to a vent-and-soil stack which is typically 4 inches in diameter. It will be laid out from under the ground floor to the roof. This adds pressure inside the system that allows the waste to flow straight to the main drain which is attached to your septic tank or the public sewer.

Vent Pipes

Vent pipes are essential to the plumbing system because they provide air that helps in directing wastewater to the right direction. All the drains in the property need ventilation but only one vent will be installed and that’s usually behind a sink. These vents are usually 2 inches in diameter and they are connected to the stack in the attic. Fixtures that are installed too far from the vent will need its own.


Drain traps are usually shaped like a letter U. These are pipes that are connected to tubs, showers or sinks. They store a small amount of water which thwarts the escape of sewer gasses. Except for the toilet, all plumbing fixtures need traps.
