What are Soil Pipes?

Soil pipes run vertically from the underground drainage system, up the side of the property to the roof level. It's the pipe that carries waste water down into the sewer system. The toilets and the soil pipe by means of a connector will connect together, and waste water from this property's sinks, bathrooms, showers and appliances will be connected from the waste pipes into the soil pipe via a boss connection.

Soil pipe is sometimes called vent pipe, because at roof level a port will be installed to allow air flow into the system, preventing a vacuum and releasing gasses and any scents.. We keep in stock both push fit soil and solvent soil ranges in 110mm, in black and grey. For more information read our "What is a Soil Pipe" guide here.

Traditionally, soil vent pipes were made out of cast iron, now they are most commonly manufactured from uPVC (plastic). Soil pipes permit the removal of waste or foul water from bathrooms, showers, baths and sinks, while also allowing odours to be expelled over the construction via a stack vent, at a level that where the smell released will not cause a nuisance. The pipe's vents also allow air into the inner drainage system in order to facilitate the process of aerobic sewer digestion, preventing a siphoning effect from occurring, and allowing free flow of water.

Approved document H: Requires that the foot of a soil and vent stack should have as large a radius as possible, rather than less than 200mm at the centre line. Offsets must be avoided in the wet section of the stack. Ventilating pipes should complete at least 900mm over any opening within 3m and should be completed with a wire cage or other perforated cover. Soil and vent pipes must keep sufficient downward slope in their length to keep liquids and solids flowing freely towards the drain. If a downward incline is not feasible, a collection pit using a 'sewer ejector' pump could be installed. It's frequently attached to the exterior of a construction (although it might be fitted internally) and connects the subterranean drainage system to a point just above the degree of this roof gutter.

What Are Soil Pipes Made From?

uPVC is currently the industry norm in house soil pipe manufacturing materials. It's a strong, chemical-resistant rigid pipe that is heat resistant and readily cut and fit. It's often used to fix segments of busted cast-iron waste pipe, in addition to repairs to additional drain lines. It also contains a UV stabilisation additive to avoid the pipes fading in the sunlight.

Cast Iron pipe is also still commonly found in the UK and is typically a high-quality soil drainage pipe that is hefty and deadens the noise of flowing waste water very well. This pipe is strong and long-lasting but tough to cut--frequently requiring a particular cutting tool with sharp string cutting wheels. Repairs are often made with PVC piping that's plastic. Cast iron is seldom utilised in new construction, in favour of plastic PVC or ABS (acrylonitrile butadiene styrene) pipe. Currently we do not stock cast iron soil pipes at EasyMerchant, but give us a call if you need some, we will be able to source it for you.

Can I connect PVC soil pipes to a cast iron stack?

This is question we're commonly asked here at EasyMerchant. Lots of our customers want to replace their old cast iron soil system with a new PVC system. Normally the installer would have to dig up the existing concrete to replace the drain connection. Luckily specialist fittings are available allowing the installer to cut the pipe, fit the adaptor and replace the rest of the system with uPVC pipe. Please call us if so we can source this fitting for you if needed.

Fittings are supplied in bags or boxes and we always take the up-most care when picking, packing and delivering our soil and vent systems, because they're in view of the customer when installed so we make sure they arrive in your hands in top condition.
