For today's drains, 1-and-a-half-inch pipes are the most popular, but two- and three-inch lines are also available. However, tubes with a diameter of 1 1/4 inches are somewhat unusual and usually only found in older sinks. A 1 1/2-inch pipe should be adequate for a primary kitchen sink drain.
Construction time is expected between one and three days, with prices ranging from £150 to £200 per day for drainage experts. We estimate that you will spend between £150 and £200 on a single day's worth of labour, £300 and £400 on two days' worth of work, and £450 and £600 on three days' worth of labour.
A drain is a pipe that carries sewage and other harmful liquids and solids from your home or business to the central sewer system. For a property to be connected to other sewers, the drain that serves that purpose on the property must be a private sewer.
The critical distinction between plumbing and drainage is that plumbing is how water comes into or is used in your house, while drainage is how water waste flows away from your home.
