About this deal

To begin with, fit a bung at the head of the pipe run with the correct nipple cap to attach it to the hose that will be connected to the manometer. Make sure that your manometer has been partially topped up with water prior to this. Once the vehicle has fully shut down the drain current reading can be gained from the multimeter. If the multimeter has been removed during the wait period, connect the multimeter to the WCDT then switch the fuse switch to OUT. After this wait a minimum of an hour and no more than 2 hours, before visually monitoring the water inside the chamber for half an hour. In most cases water loss of below 25mm over the course of 10 minutes is classed as a pass but if you are unsure you can use the same calculation as with the pipes to find this out.

Furthermore, before the drain test begins there will have to be a drain testing procedure building control officer there at the time. However it must be noted that it is best to ensure that the drainage has no immediate errors while flowing through the pipes, by running the system prior to having the officer observe the test. What is smoke testing? There are two types of test parameters that must be followed, depending on the size of the pipe you will be using. If the pipe diameter is in the range of 100-400mm then the rules for BS8301 should be followed. This means a 1500mm head at the high end and a maximum head of 400mm at the low end. If your pipe is between the ranges of 400-750mm then the rules for BS8005 should be followed. This means a 1200mm head at the high end and a maximum head of 6000mm at the low end. At EasyMerchant we offer both an air testing kit and drain testing kit to suit the requirements for your job. The drain testing kit essentially includes the basics required to test a drainage set up:

Officially, smoke testing would not count as a genuine examination of a drainage system’s ability to function correctly in terms of water tightness. However it is useful to use with uPVC piping to establish leaks and other faults that may not have shown up during a water or air test. Drain testing bags are used in a variety of industries such as Sewerage, Petrochemicals, Food Processing, Mining etc. The reason for this is due to their adaptability and ideal use in places with a smaller area than the test diameter. The smaller sizes tend to be fitted with Schrader valves, or brass air traps and bigger ones are fitted with ball valves for inflating using a compressor. If necessary it can also be fitted with a pressure gauge to prevent over inflation. After water is filled to the top of the manhole benching, it should be left to soak for 5 minutes before begin topped up. It should be left to charge for 10 minutes more, before topping up again once the changes have been recorded. We’ve highlighted the values of leakage over a 10 minute period in our lovely table below.

The ‘drop’ test is a low-pressure method of drain testing. It works by isolating the downstream end of the drain with a bung, before charging the system with water and monitoring the water levels either at a manhole or a pipe access point.After this, add water to the required head level in the vertical pipe based on which rules you are following (BS8301 or BS8005). Proceed to let the water stand for two hours before topping it up to the essential level stated on the guidelines specific to the sizes you may have. Air Test – for single pipes or individual drain runs. The air pressure test is effective, but it can only be used to test a length of a drain that can be capped at both ends. A drain test kit is used in construction to test the proper functioning of a building's drainage system.

The kit typically includes a variety of tools, such as a flow meter, pressure gauge, and plugs or stoppers, which are used to perform the tests. Before attempting to fit the bungs for pressure testing ensure there are no issues or dirt that could prevent the installation and function of the bung, as any grit or dirt within the seal could allow leaking and thus fail a test.CMT Group ensures that you, our valued customer, enjoys your shopping experience as we strive to make your experience ‘hassle free’. You may be wondering what happens with drains less than 5 metres long. In this case, it is a matter of judgement whether the leakage is significant. Generally, a drop of less than 25mm in 10 minutes is acceptable; however, if there is damage to the property as a result of the leak, there is a problem! How to Undertake a parasitic Current Drain Test? Necessary Conditions to perform Parasitic Drain Test The process does not differ far from that of the regular water test. Firstly all of the ends of any open ended outlets etc must be bunged up and then the manhole chamber must be filled with 300mm of water. It is not uncommon for the need to undertake repairs after running a drainage test. Often, it may be a case of a faulty length of drainage pipe or a joint that may need re-doing. However, if there is no obvious fault it may require disassembly of the system entirely and individually testing each section using an air test. After the fault is correctly identified, tests must then be rerun to ensure everything runs as it should. It may be that there is a need for a new length of pipe or the need to re-join or reseal parts of the system.

Water testing, also known as water drop testing, is a method of testing drains which requires less pressure but, unlike the air test, may take up to 2 hours to set up. The test itself works through bunging up the two ends of a system, charging the system with water and overseeing the water levels either at a manhole or access point. No additional pressure should be applied when performing the water test. This means that the water level should be limited to 1.5 meters from the lowest invert level of the drain being tested. This method has the positive of being able to test a whole system at once which can be beneficial for everyone involved in the process. Drain testing procedure for a water test.During this shutdown wait period the fuse switch can be switched to IN and the multimeter can be removed to carry out other tasks. Remember to reconnect the multimeter before switching the fuse to OUT to prevent waking the car up when reconnecting. Parasitic Current Drain is a vehicle diagnostic term that describes the situation when an on-board electrical device draws electric current from the vehicle’s battery when the vehicle ignition key is turned off. To find out more about the air test, you can find more details in BS EN 1610 and in Building Regulations Approved Document H. By filling a chamber to the top with water, no additional pressure should be imposed during this drop test. For this reason, the head of water should be minimal and, where practical, should be limited to 1.5 metres, measured from the lowest invert level of the drain being tested. A specific Parasitic Current Drain value is therefore expected to ensure the vehicle shuts down and prepares successfully. An issue only arises when the Parasitic Current Drain exceeds the manufacturers stated value (refer to vehicle technical data for specific test conditions and results.) If the excess current drain proceeds whilst the vehicle is standing inactive the battery becomes insufficiently charged and unable to perform an engine start.
