Soil pipes also need to be larger in diameter than waste pipes on the account of having to handle more…solid materials. While having your sink drain into a soil pipe wouldn't really matter much (apart from using up an unnecessary amount of space under it), having your toilet drain into a waste pipe would be a recipe for a very unpleasant disaster in your home.

But why is it important to make this differentiation? Why can't one pipe service all wastewater needs if they both carry it out to the sewer? Why does it matter whether you use soil pipes or waste pipes? The answer lies in what they are used for and the way they are vented. Materials used in drainage an vent pipes according US standards.

Replacing old cast iron soil pipes can be a daunting prospect, so EasyMerchant have put together some information that'll help you get to grips with the task at hand. Dealing with plastic systems is a lot more straightforward, as most plastic drainage pipes are designed to be compatible with each other regardless of the manufacturer. If they aren't, conversion fittings are usually readily available to make connections as easy as possible. The only caveat to this is that different connection types shouldn't generally be mixed. For soil pipes, the two main connection types are either Ring Seal or Solvent Weld, meaning that if the system you are connecting to is a Solvent Weld system, you should ideally be using Solvent Weld pipes and fittings rather than Ring Seal, and visa-versa. "But what is the difference between these two connection types?" we hear you ask. Well, fortunately enough, we have written a separate article (Ring Seal or Solvent Weld - which soil pipe system is better?) to answer just that. In some cases, such vents will have a covering to prevent insects or birds from getting into the pipe system. Drain pipes, which collect wastewater directly from water fixtures. These fixtures can include your toilet, kitchen sink (secondary drain line), shower, or bath tub.

A waste system, as previously mentioned, is made up of pipes and fittings designed to carry wastewater from sinks, showers, bathtubs, washing machines, and dishwashers out to the sewer. Because these pipes shouldn't have to carry any solid waste away (stop scraping leftover food down the kitchen sink!), they don't need to be as large a diameter as the soil system pipes, meaning that less space is required to install them. The most common waste pipe sizes in the UK are 32mm (suitable for low volume outlets, such as small hand basins), 40mm (suitable for most kitchen sinks, showers, and baths), and 50mm (suitable for more commercial applications, or for connecting multiple waste pipes into a single flow. Plumbing or sanitation codes are a set of rules and regulations imposed by cities, counties or states. One of the first considerations is the distance of the proposed fitting from the nearest foul water pipe or manhole. Let us look at the table below for some of the critical drain-waste-vent system sizes: Drain Pipe Size (inches) According to HK Legislation Cap 123I Building Regulations, traps of bathtubs should have a minimum 40mm water seal. If the bathtub waste pipe is connected to a soil pipe, a minimum 80mm water seal is required.If you ever experience sewage smell in your house, either the P-trap is leaking or the plumbing vent is clogged. A clogged vent forces sewer gases to flow out through drains and you will notice the toilet bubbling when flushed or the tub drain gurgling when the toilet is flushed. Brett arrived when scheduled.
