Vent Cowl Cap 110 mm - Grey - Grill - Cover - Soil Stack - Vent Cage - Rain Hat 4"

Product Information

The second vertical drain line section that connects to the first horizontal branch pipe under your home’s foundation may have a clean-out cap installed at its termination point so you can access it during non-building seasons or if needed. This clean-out cap may have a removable closure that allows access to the interior of the pipe without being too large so debris cannot enter the system through it. The majority of these caps are made from brass with either threaded or slip-fit connections.

An ‘air trap’ is a clear vertical area between the water outlet and flood level of the actual installation. 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. 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. 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. By legislation, ventilation pipes must be able to handle an air test of 38mm of pressure on a water gauge for three minutes. A 25mm water seal should be maintained. It is important to always test pipes after an installation because if there is not the right balance in pressure, it could even lead to burst pipes. Along with this, in the winter months an inconsistency in pressure may lead to things such as dried up taps as well as various other problems. So to ensure your whole system runs as it should make sure to correctly carry out the drain testing procedure. For more information on testing pipework properly you can see our ‘All about drain testing’.

Beware of the Con Artist: How to Spot and Stop Home Maintenance Scammers

Combination Waste and Vent System. A specially designed system of waste piping embodying the horizontal wet venting of one or more sinks or floor drains by means of a common waste and vent pipe adequately sized to provide free movement of air above the flow line of the drain. 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.

Individual Vent. A pipe installed to vent a fixture trap and that connects with the vent system above the fixture served or terminates in the open air. Conversion Bends - used to create changes in direction while also converting the connection type between push-fit and solvent weld.

Summary of the regulations on traps. Common Vent. A vent connecting at the junction of two fixture drains or to a fixture branch and serving as a vent for both fixtures.
