How Drains Get Rid of Waste Water

How Drains Get Rid of Waste Water

Every drainage system in every home is different. New build houses are likely to be all very similar but every additional tap, new shower or extra radiator will change the route the water takes behind the scenes in your home.

Drain Unblocking

Whereas, older homes are likely to be plumbed up differently, with different methods and materials, and after 20, 30 or 40 years of repairs and adjustments, is unlikely to resemble the original system at all!

They do however all function the same way – with fresh water being supplied from the mains and delivered throughout your home, via the water heater or boiler or straight to your cold water taps and appliances.  And of course they all have a waste water, or sanitary drainage system to remove waste water from your home hygienically and efficiency.

Waste water systems comprise of a series of waste pipes, water seals and vents that lead from every sink, toilet, bath and shower, as well as your washing machine and dishwasher, allowing the soiled fluid to flow from your home drainage system and away into the main sewerage pipe.

 

Avoiding Siphonage

All systems that carry fluids and gases contain pressurised areas and vacuums to maintain the function and allow the free flow of the gases as well as the fluid. These are known as ‘traps’ and are where the pipes curve down then back up to ‘trap’ a little bit of water and create a  water seal between the inside air space and the rest of the drain to stop nasty gases flowing back into the home.

It is essential that every drainage system has space to accommodate the free flow of air in the waste water pipes as they will not function if they are totally full of fluid. If they do fill with fluid the natural balance of the system will be disrupted which could increase the risk of siphonage.

This means the water seals, or the usual water level in the toilet and u-bend of the sinks, could be sucked away or disrupted allowing the unhygienic, noxious odours to escape into the living spaces.

 

Venting Your Waste Water System

The other main component of your waste water system is the vents that help alleviate siphonage, draw away bad odours and ensure the waste water continues to flow and drain effectively by relieving the air pressure.

The venting system is a simple system of pipes that divert the sewer gasses out of the building to the outside air. It prevents the water being sucked from the seals and provides an effective escape for the gases that could otherwise build up in the waste system.

Without adequate vents, these sewer gases can build up and push water back through the pipes, which could result in waste water being forced back into fixtures and drains and becoming a serious health and hygiene hazard.
