ASL Limited blocked drains engineers:

As a result of years in assisting with drainage work, gaining experience, knowledge, and skills, our staff can serve as our block drains engineers – equipped with an up-to-date, fuel-efficient vehicle, high-pressure jetting machine and a basic drain camera.

Our block drains team: 

Each individual is competent and very confident, working with and around your home’s drainage. Most blocked drains are often unblocked within 30 minutes; however, they come across homes with private systems or pumping stations. Training and experience are invaluable in finding the solution, especially after listening to their colleagues’ directions in our other departments.

Once found, they will relay the information to one of our fully qualified electrical engineers – if necessary or the private systems department; small tanker emptying service; cleaning department; or excavation teams. Our blocked drains engineer has them on speed dial, knows and is familiar with them on first name terms.

What are the signs that my drain is blocked?

Sometimes it takes a while for the signs of a blocked drain to become apparent, and I believe this will help you:

  • A nasty smell inside the house or outside.
  • A slow-draining sink, shower or bathtub, gurgling noises – in severe cases, overflowing.
  • Toilet drainage problems – again gurgling noises after you flushed or water level rising or overflowing after flushing.
  • Gurgling noises may indicate something not being quite right with the drains, possibly the drains partially blocked.

You can find out more using our website’s site search feature or browsing the ASL Limited blog articles all about drainage.

May I remind you

Be careful what you put down the drain via the toilet or the kitchen sink to avoid blockages:

  • Food waste
  • Fat, oil, or grease 
  • Cleaning wipes
  • Razor blades
  • Plastic bags
  • Nappies
  • Sanitary towels, including tampons
  • Cotton buds
  • Condoms
  • Wet cement slurry or plasters 
  • Baby wipes
  • Medicines, needles, and syringes (Try your local pharmacy or health authority for safe disposal)

Our blog article entitled ‘Drain blockage prevention and how to clear plugholes’ will help you prevent blockages in your home.
