Sewer and drainage maintenance

Our drainage specialists can help you maintain your drains and sewers to prevent blockages and discourage pests.

All drains and waste pipes require periodic maintenance and cleaning to prevent the accumulation of scale, silt, and grease or debris that can reduce the pipe bore. A reduced capacity within your drainage system increases the likelihood of expensive blockages occurring, with the potential to cause severe problems from leaks and pipe ruptures. Initial hygiene's drainage specialists provide preventative maintenance for your drains and conduct a full disinfection service in case of a leak or drain pipe rupture. We can also offer deep cleaning and disinfection services where the blocked drain causes the pipework to break and leak.

What is sewer maintenance?

Sewer maintenance refers to the upkeep and repair of a building's plumbing system and its connection to the more extensive drainage system often referred to as the sewer system. Sewer maintenance involves inspecting, cleaning, and repairing the plumbing system and sewer pipe to ensure they function correctly. This may include using specialised tools and equipment to clear blockages, replacing damaged tubes, and performing other repairs as needed. Regular sewer maintenance can help to prevent problems with the plumbing system and sewer pipe. It can also help to extend the life of these essential components of a building's infrastructure.

How do you tell if your sewer line is clogged?

There are several signs that you may have a clogged sewer line, including

  1. Slow or clogged drains: If multiple sinks, toilets, or other plumbing fixtures are draining slowly or not at all, it could be a sign of a clogged sewer line.
  2. Foul odours: A blocked sewer line can cause sewage to back into the building, resulting in unpleasant odours.
  3. Toilet overflow: If your toilet is overflowing or you notice water around the toilet's base, it could signify a clogged sewer line.
  4. Gurgling sounds: If you hear gurgling sounds from the drains, it could signify that air is being forced through a blockage in the sewer line.
  5. Water backups: If water starts to back up out of a drain or sewage starts to back up into a building, it strongly indicates a clogged sewer line.

If you suspect that you have a clogged sewer line, it is essential to contact a professional drainage company for assistance. They can diagnose the problem and recommend the appropriate action to fix it.

How do you inspect a drainage system?

There are several steps involved in inspecting a drainage system:

  1. Identify the location of the plumbing system and sewer pipe: The first step in inspecting a drainage system is to locate the plumbing system and sewer pipe. These are typically located beneath the foundation of a building or in the basement.
  2. Inspect the plumbing system: The next step is to inspect the system itself. This may include checking the pipes for any visible damage, such as cracks or leaks, and looking for any blockages or clogs.
  3. Inspect the sewer pipe: Once the plumbing system has been inspected, the sewer pipe should be examined next. This may involve using specialised tools and equipment, such as a sewer camera, to examine the inside of the pipe and look for any blockages or damage.
  4. Test the drainage system: After the plumbing system and sewer pipe have been inspected, the drainage system should be tested to ensure it is functioning correctly. This may involve running water through the system and checking for issues like slow drainage or backups.

Overall, inspecting a drainage system involves thoroughly examining the plumbing system, sewer pipe, and overall drainage system to identify any problems or issues that may need to be addressed. This is typically done by a professional drainage company with the knowledge, experience, and specialised tools and equipment to properly inspect and diagnose any problems.
