The Klober Uni-Line Flexipipe Soil Pipe 100/100mm 4" is an excellent choice for use alongside tile vents. As it effectively facilitates mechanical ventilation or soil extraction throughout a property.
Moreover, its naturally lightweight design makes it easy to handle, especially in confined roofing spaces. In addition, the straightforward installation process simplifies the entire project, helping roofers complete their work more efficiently.
It's important to equip your house with one of these to enable mechanical ventilation and, more importantly, soil extraction. The reason why it's essential to allow soil extraction to occur is to prevent unwanted damage to the area. Too much pressure in a toilet can cause floods, whilst negative pressure can cause the water to suck and seal away, filling the property with awful smells and toxins.
