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. 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." 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.

Mandrel testing is used to gauge the quality of an installation. It is a small object that is sent through the interior of the pipe to assess that the consistency of diameter throughout the pipe is adequate. They have a smaller diameter in comparison to the pipe itself, so for example if the pipe was 150mm you would look to use a 135mm mandrel. They can be identified as a cylinder like object. 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 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. 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. 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.

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. 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. Roller bearings fitted as standard on all plugs 9" (225mm) & above to make tightening up of the plugs even easier

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. CMT Group ensures that you, our valued customer, enjoys your shopping experience as we strive to make your experience ‘hassle free’.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 drain test kit is used in construction to test the proper functioning of a building's drainage system.

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. When it comes to manhole covers and inspection chambers, it is common for joints to leak but is usually an easy fix through the process of re-joining and resealing. However it may be a structural problem with the base and the concrete with the sealing of the pipe. If this is the problem and epoxy mortar doesn’t fix it, the only option is to completely rebuild, which is not ideal but necessary in accordance with regulations. Once again always retest after attempting to rectify any faults within the system. How to water test a manhole and inspection chamber. Inflatable sizes 100 – 1200mm incorporating 2"/50mm or 3"/75mm or 4"/100mm or 6"/150mm or 8"/200mm Bauer connection. 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.closed cell sealing surface, car wheel type - 1/4" BSP female valve for inflation and lever ball valve for rapid deflation
