<p>This Architectural Drawing is Soil pipeline path in bathroom. A soil pipe is <strong>a pipe that conveys sewage or wastewater reliably, either from the toilet or sink to a soil drain or sewer</strong>. It is always placed <strong>above the highest waste water inlet into the pipe</strong>. A vent is usually located above the roof, so odours and gases can escape harmlessly without causing a nuisance to the property occupiers or neighbours. They are relatively easy to spot as they run vertically from the underground drainage system to the top of a property, where they reach the roof gutter. Decorations. If you don't want to go to the house of boxing in your pipes or building fake walls, then a much simpler (and cheaper) way of hiding the pipework in your bathroom is to use decorations. Decorations can be as simple as <strong>winding some fake flowers or ribbons around the pipes or using rope to obscure them</strong>. As long as the pipe have at least 15% downhill slop from Toilet to main waste pipe it would be ok. <strong>Any distance up to 3m do not require extra joining points as standard 4inch waste pipe is 3m long</strong>. That is how manufacture made it. You can buy shorter too but 3m long is no problem to get. For more details and information download the drawing file.</p>
