Note: the vast majority of properties in the UK still use potable water to refill toilet cisterns after flushing. Therefore, to avoid wasting that precious water, multi-flushing should be reserved for only those times when paper rationing isn’t...practical, shall we say. Alternatively, why not look into getting ahead of the curve and invest in a rainwater harvesting system? You could save money and help the environment by using stored rainwater to fill your toilets and supply your household appliances. Have read of our “What is rainwater harvesting and why is it important?" article to find out more. Conversion Bends - used to create changes in direction while also converting the connection type between push-fit and solvent weld. Note: If your property uses a sewage treatment plant, septic tank, or cesspool instead of a connection to the mains drains, there must be AT LEAST one open vent in the system to prevent a dangerous build-up of gasses. Solving pressure build-up with an Air Admittance Valve They offer an extensive choice of systems and products, in a range of sizes and colours, to suit all tastes and applications. Their Soil & Waste Systems offer a comprehensive, integrated and modern range of products for all soil and waste applications. Colour matching between systems facilitates colour coordination where sanitary pipework is located externally.

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.

Properly maintaining your soil and waste systems is the best way to avoid the need to repair or replace them, and there are a few simple things you can add to your household maintenance routine to achieve this.

FloPlast's Soil& Waste Systems may be used to carry liquids, when subjected to a continuous flow, with a maximum temperature of 76 degrees C. Intermittent discharges of up to 100 degrees C may occur, provided that a duration of less than two minutes is observed.

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. Traditionally, most waste pipes used to be made from either copper, iron, or lead, and many properties may still have systems that are at least partially comprised of these materials. Copper is actually still quite popular today, among some professionals, as the pipes can be made to fit into tighter spaces, are more flexible at the joints (therefore offer good resistance to vibration damage), and have a certain premium aesthetic appeal. The more modern alternative to copper waste pipes, however, is plastic. Each have their own pro's and con's, but the popularity of plastic pipes has grown exponentially due to the fact that they are much less expensive than copper pipes, easier to install, more resistant to corrosion and impact damage, and quieter at high pressure and water speeds.

Hiding within the walls and under the floors of your home, there are many different types of pipes coming and going. Some supply you with clean water, and others take away the waste so you don't have to worry about it. While the difference between water pipes and wastewater pipes is quite clear, the difference between soil pipes and waste pipes can be a bit murkier. Fortunately, if you have an existing system of copper piping but want to make repairs or install additional pipework using plastic pipes and fittings, many manufacturers, such as FloPlast, do have compression waste ranges that can make this happen. If you already have an existing plastic waste system, or are looking to install a new one, the biggest choice you have to make is whether to use Push-Fit or Solvent Weld connections. Again, as with the connection choices for plastic soil systems, we have put together a dedicated article, (Push-Fit or Solvent Weld - which waste pipe system is better) to properly evaluate the uses of each. A more modern alternative solution to the pressure problem is to install an Air Admittance Valve instead of a vent pipe. Sometimes known as Durgo Valves, Air Admittance Valves (or AAV's for short) are essentially one-way valves that can be installed at the top of the soil pipe, or along a waste pipe run, to allow the free entry of air into the pipework system to balance out the pressure. The design of these valves is quite clever, as they only open when the siphoning pressure (the negative pressure caused when water flows into the pipes) builds up enough to require balancing, and only in a way that allows clean air to be drawn in without allowing foul air to escape. This is the crucial difference between the valve and the vent.

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. Weathering Collar - used to divert rainwater away from falling directly onto the weathering slate to provide extra protection.

A typical plastic waste system (be it Polypropylene Push-Fit or ABS Solvent Weld) will be comprised of 32/40mm pipes and fittings connected to either:Since its foundation in 1991, FloPlast has established itself as a manufacturer of high quality plastic building and plumbing systems for the construction industry, in particular domestic and commercial new build and refurbishment projects.
