Clearing a blocked drain - so bad that no water could flow through it.

2021/09/01

I rent a property in Surbiton and tenants reported to me that whenever they emptied the sink, none of the water actually went down the drain as it was so clogged and just overflowed into the front garden. Harvey arrived with a generator and used drain jetting to clear it. Must have been a build up of cooking fats etc, now water flows away easily. Thanks Evo!

DIY guide to unblocking a sink

Follow our step-by-step guide to unblocking a sink:

  • Clear the plug hole. Do your best to clean it as well as you can as this will make it removing the blockage easier.
  • Use bleach to remove the blockage. Once applied, leave the bleach to sit in the sink as long as you can before flushing it with hot water. Allowing it to sit overnight will give you a good chance of clearing the blockage. Be careful with chemicals and always use in a ventilated area.

Still no luck? This could be an indication of a more severe blockage. At this point, we advise that you drain the sink and check the U-bend. To do this, place a bowl or container below the bend. Gently unscrew the U-bend and allow the water to drain away. Whilst the water is draining, examine the U-bend and give it a good clean; removing any debris that is blocking the tube before you screw it back into place.

Aaron arrived bang on time, was painstaking in his work, although young he had rare old school ethics and wanted my 40-year old Potterton boiler de-scaling to be perfect. Took extra time to see it spotless with courtesy. A huge credit to his company.
