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. So, you have a problem with your drains and call an expert to out to test them. How exactly does the drain testing process work?

Our mechanical testing equipment covers the full spectrum of test analysis applications, including: 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. A drain test kit is used in construction to test the proper functioning of a building's drainage system. 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. 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.All new drains and sewers laid in the UK must be subjected to an air pressure test in accordance with BS 8005. For sizes above 300mm in accordance to BS 8000 or BS EN 1610. Air Test Kits contain 'U' air gauge, hand bellows, approx. 2m (6'6") rubber tubing, 13mm (½") nipple cap, 'Y' piece and full operating instructions 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.

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." Next, the manometer must be monitored for five minutes and within this time it must not drop below 75mm. This will be considered a pass, however if it does reduce to below the 75mm line on the manometer there should be an examination for leaks and other signs of failure. If anything needs rectifying this must be complete before conducting another test and if this fails move to a water 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. 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. Inflatable sizes 100 – 1200mm incorporating 2"/50mm or 3"/75mm or 4"/100mm or 6"/150mm or 8"/200mm Bauer connection.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. 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. 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. Pre-set relief valve to suit stopper size connected by 1200mm umbilical tube.

How to Undertake a parasitic Current Drain Test? Necessary Conditions to perform Parasitic Drain TestThe ‘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. 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. 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.

Can be supplied with twin outlets – lower outlet allows complete emptying of water from the drain before removal of the plug 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. 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. 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!
