Drainage Systems

Understanding your drainage systems

Plumbing, in its simplest form, is holding and controlling the water supply as it flows round your home.

The concept of water moving through pipework is extremely easy to understand. Water enters your property through a mains supply line and is distributed, through pipes, to our fixtures such as taps, shower, toilet cistern etc. for us to use.

What is drainage?

Once we have used the water it has to travel back through the pipes and out of your property to the sewage system. Water travelling out of your property is known as drainage.

Because the drain system works by gravity, and not by water pressure, it is important for the pipes carrying the water away to be angled to keep water constantly flowing through to the sewer.

As you would expect the less a pipe is angled the slower water travels through. Vertical pipework obviously carries water away faster than pipes that are running horizontally. The horizontal sections of our drainage system gradually build up deposits of grease and soap residue which, over time, can cause your water to drain slowly and eventually lead to a total jam.

U-bends or traps

U-bends in pipes are sometimes known as traps. The U bend in the pipe forces the water that is travelling through the drainage system to travel upwards momentarily. This can only happen when more water, from higher up the pipe, is pushing it though. As soon as no more wastewater is pushing though some of it is still in the u-bend. This effectively blocks the pipe so that no sewer gases can escape up through the drainage system and into your home.

Leaking pipes

Because water stays inside the pipework the u-bend sections can, over time, become corroded and leak. That is why you often hear the term ‘a leak under the sink.’ Why? because a u-bend is always under the sink for the reason outlined above. Often a leak from under the sink is a simple case of replacing the trap or u-bend section of the drain.

If you do and that you have a leak under your sink the first place to check is the u-bend section. If that is not the cause, then check the sink filter assembly (the section directly under the basin) to see if the origin of the leak is here. If so, call a plumber to replace the assembly.

Blocked pipes

Blocked pipes usually occur because of deposits such as hair, grease, food, or other debris getting build-up in the u-bend or fixture drain line.

If a plunger does not work, it is time to call an emergency plumber to fix the problem.

Unclogging or cleaning blocked drains can be tricky and require specialist knowledge of pipework and connections so that you can take things apart, replace anything that is faulty, and re-assemble everything securely so that its sealed once again. It is always best to call in a plumber to tend to any blocked pipes and drains in your home.

Caring for your drainage system

Many potential drain problems can be averted with a little regular care. kitchen drains tend to have the most grease and debris to deal with and should be flushed at least once a week with hot or boiling water from the kettle. Bathtubs and shower tray drains may receive help from a small dose of liquid bleach to help clear things through.
