Air (or in some cases water) is then pumped into the line. <\/p>\n\n\n\n<p>The engineer will the monitor the drop in pressure over a 5 minute period. A large drop in pressure over this time will indicate defects in the line. <\/p>\n\n\n\n<p>This would indicate a failure. The only information that a drain test will give is a &#8220;pass&#8221; or a &#8220;fail&#8221;. There is no other information available from your drain test.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why do people have drain tests?<\/h2>\n\n\n\n<p>The only reason that people ever have a drain test done for a property is that Building Control tell them they have to have a test done on new drainage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What happens if a drain test fails?<\/h2>\n\n\n\n<p>The next step would be use a cctv camera to check the line for any defects in the line. Once any defects are found and repaired, the test can be redone.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Do I need a drain test done before I buy a house?<\/h2>\n\n\n\n<p>The simple answer is NO. If you are purchasing a property, you need to know that there are no leaks in the underground drainage that could be affecting the structural integrity of the house by causing subsidence. <\/p>\n\n\n\n<p>If there are any you defects, you need to know how much it will cost to carry out the repairs. For this you will need a cctv drain survey NOT a drain test.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We are contacted by many prospective house purchasers every week.
