Can a soil pipe vent in loft?
Yep, the soil pipe is the one you’re thinking of. This large, grey pipe is supposed to reach your roof or an external wall and be vented to the outside air. Not, as we so often see it, venting to the loft space.
Does a soil pipe have to be vented?
Soil vent pipes are a critical part of any drainage system. Without a vented pipe, a vacuum would build up behind the waste water as it moves down the pipe. This would force the water out of u-bends, in turn allowing foul odours and gases to enter the property.
Can you run a soil pipe under floorboards?
Soil pipes are generally located on an outside wall and enter the bathroom as close as possible to the toilet location. They can be mounted on the floor, but usually pipes run below the floor in-between the floor joists. Running this pipe from one end of the house to the other simply is not practical.
Can you have an internal soil pipe?
A soil vent pipe commonly runs vertically from the underground drainage system to the top of a property, just above roof gutter level. It is also known as a soil stack pipe, a drain waste vent or a ventilated discharge pipe. Soil vent pipes can be installed inside structures.

Can you vent sewer into attic?
Yes, a plumbing vent can terminate in the attic. But it must have an air admittance valve at the termination to keep noxious sewer gas fumes from rising into the attic. Also, the air admittance valve must be at least 6-inches above the attic insulation, and there must be at least one other vent that extends outdoors.
What is the difference between a waste pipe and a soil pipe?
At a very basic level, waste pipes are designed to carry just water and other liquids out of your home. Soil pipes are pipes that are designed to carry “soiled” water from your home – that means any water, or substances, that were in a toilet, bidet or urinal.
Where does a soil pipe go?
A soil pipe is a pipe that conveys sewage or wastewater reliably, either from the toilet or sink to a soil drain or sewer. 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.
Can you have a toilet without a soil pipe?
A Saniflo is normally installed in a domestic property where there is no mains drainage pipe available. This means you can have a toilet anywhere, without worrying about mains drainage. A Saniflo macerator allows you to install a toilet up to 150 feet from your main drainage pipe.
What fall is required for soil pipes?
The most important bit of obvious advice ever: soil and waste pipes need to be on a downhill gradient! The “fall” or “drop” should be between 1/40 (1cm down for every 40cm across) and 1/110. Too steep (1/10) then the water runs quicker than the solids so doesn’t wash them away (ugh!).
Do you need planning permission to move a soil pipe?
Fitting, altering or replacing an external flue, chimney, or soil and vent pipe is normally considered to be permitted development, not requiring planning consent, if the conditions outlined below are met: In a designated area the flue should not be fitted on the principal or side elevation that fronts a highway.
What kind of pipes are in the attic?
There are two types of pipes, other that water supply, that are typically found in an attic: 1) vent pipes for the plumbing drain system, like in the photo above, that extend through the roof and are usually larger diameter and, 2) piping for natural or propane gas that runs through the attic and then down to a furnace …

How does height affect the cost of converting a loft?
Loft conversion costs will be significantly lower where you’ve got a suitably spacious loft to start with. A generous height is the most important factor, and if the existing floor area is also a reasonable size it should make it easier to install large beams and loft stairs without major surgery.

All bathrooms require a waste water system, so this is something you will also need to consider when installing your new loft conversion ensuite. Your waste water will go down large vertical pipes which leads to the drainage system underground.
