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. Roller bearings fitted as standard on all plugs 9" (225mm) & above to make tightening up of the plugs even easier. Surprisingly new vehicles are susceptible to engine start issues from Parasitic Current Drain. The power demand from the vehicle battery has increased in direct proportion to the technology now installed in high-specification vehicles. Comprehensive Range Of Fibre Installation & Testing Equipment Is Available To Hire Today With Next Day Delivery and Technical Support Before moving forward with a drain test all the pipelines should be examined for any upfront impairment or leakage. If the system that you are planning on testing are jointed systems, make sure to let them completely drain out for two days before starting any tests, so that any problems can be clarified.

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.If your length of drainage is below five meters it would be a case of using common sense to assess whether the leakage is acceptable or not. A good rule of thumb to go by is if there is damage to the place where you are undertaking the test then it is not a good sign and there is probably more water than there should be. On the whole it is common knowledge that an amount less than 25mm in ten minutes is not deemed enough to be a concern.

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. 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? We offer industry leading equipment for process calibration across a wide range of plant, machinery and process applications. This includes:Comes with 'U' air gauge, hand bellows, 2m tubing, 13mm nipple cap, 'Y' piece, and 2 x 4" (110mm) nylon test plugs. Full instructions included with the equipment. 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. 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. 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. The majority of vehicles have a Parasitic Drain value as on-board computers operate to initialise alarms, run system integrity tests and many more tasks that prepare the vehicle for shutdown and preparation for the drivers return. All of which are completed whilst the batteries charging system is inactive.

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.

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. Sleep mode is typically when Parasitic Current Draw from the battery settles at approx 30-40 mA for over 20 minutes. The target maximum Parasitic Drain Value is < 80 mA and stable throughout." 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. Inflatable sizes 100 – 1200mm incorporating 2"/50mm or 3"/75mm or 4"/100mm or 6"/150mm or 8"/200mm Bauer connection. A drain test kit is used in construction to test the proper functioning of a building's drainage system.
