Common plumbing mistakes include using harsh chemical drain cleaners, over-tightening connections, not turning off the water supply before repairs, using the wrong materials or tools, ignoring small leaks, improperly disposing of grease/food, and DIYing major issues without proper knowledge or permits, leading to costly damage, code violations, and bigger problems like clogged drains or pipe corrosion.

Pipes must slope slightly downhill to drain properly. The standard slope is anywhere from ¼ inch to 3 inches per foot depending on the use. An accurate calculation is essential for properly functioning plumbing.
You can unclog a vent pipe from inside by using a plumber's snake through the nearest clean-out access. This method allows you to reach blockages without having to go onto the roof.

Pressure Testing: Plumbers can pressurize the plumbing system to identify leaks by monitoring pressure drops. This method is particularly effective for detecting hidden leaks in pipes. Infrared Technology: Infrared cameras can detect temperature differences caused by water leaks, making them an invaluable tool.
The typical cost for a professional water leak detection service in the UK ranges from £550 to £1,250.
