What a Northampton CCTV Drain Survey Finds After Blockages has been a very popular post.
The problems a blockage has caused may not have cleared with the drain clearance. A CCTV survey may reveal other problems that have been caused by the blockage or which the blockage has exacerbated.
Fat and Grease Coating the Walls
Although jetting clears the blockage, there is usually a lot of solidified fat left on the walls of the pipes. This appears on the CCTV images as a narrowed, discolored pipe. It will soon fill up with other debris and block again, so needs a priority flush to clear.
Root Intrusion at Weakened Joints
As wastewater from within a property builds up under pressure, this can exert a pressure on the pipe joint. Often this can cause softening of the seal between the pipes allowing access for tree roots to enter and cause further problems. A CCTV drain survey Northampton will provide images of the joints to locate where any root intrusion may have occurred allowing for an appropriate repair to be made.
Cracking From Pressure Build-Up
During a blockage, pressure from the coming water can stress older clay or pitch-fibre pipes causing hairline cracks or even fractures to appear. Although these do not necessarily leak immediately, they do represent potential problems in the future as further heavy flows may exacerbate the situation.
Displaced or Misaligned Joints
Debris accumulating in a blockage can cause pipes to shift and become misaligned. When performing a CCTV drain survey the misalignment is usually evident by steps or a large gap at the joint. This type of problem causes constant problems until it is corrected.
Silt Build-Up in Low Sections
Silt in low points: The worst type of blockage! If your property has a poor gradient then wastewater will slowly flow through the drain and deposit silt in low points. A CCTV Drain Survey Northampton will determine where the drain has sagged and is laying flat in certain sections.

Check who is responsible for drains, e.g. water company or individual property owner, before spending money on a repair.
Knowing exactly what your drain damage looks like ensures that a repair list can be compiled accurately rather than speculatively.
