help with slow drains

Question

What causes slow drains? Is this a serious problem? How can I identify specifically what’s causing it in my case?

Lee · Answer

Recommend full clean with high pressure water jetting equipment to all external drainage . this will increase flow rate to drain lines serving property, would also full clean internal drainage lines.


This is caused by heavy lime scale /fat and grease

William · Answer

Slow drains can be caused by multiple things,
Build up of scale in drain, root ingress, backfalling pipes,
Displaced pipes, breackages or even just poor fall in drain itself.
A drainage CCTV would be advisable

Barry · Answer

Slow drains are caused by a partial blockages normally and 
Just require unblocking

Derek · Answer

COULD BE ONE OF SEVERAL THINGS
NOT A LOT OF FALL ON THE PIPE RUN 
BLOCKAGE IN PIPE RUN = ROOTS ETC
BROKEN PIPE IN RUN IT WILL STILL RUNAWAY SLOWLY WITH ALL THESE
YOU COULD ALWAYS HAVE A CAMERA SURVEY DONE

Chris · Answer

This could be a number of issues and depends on a few factors?

Where is it draining slow? Bathroom, Sink, Toilet?

Has this always been an issue or just recently?

In some case the drain line could not be at he optimal fall (Slope) to carry water and foul away.

Could be a soft blockage or a build up of scale/Fat/Oil/Grease which is letting water past slowly 

It can sometimes be caused bu displacement creating a step for water to get up.

It's only an issue if it causing you the owner an issue I guess. If so it would need some investigation works and remodel works would be dependant on the issue.

Hope that helps.

A few issues can cause slow flowing drains. A partial blockage in the drains may affect flow and also a possible venting issue. It's difficult to say for certain without seeing the drainage layout and the actual problem and what is affected. Hope this helps
Kind regards

Good Morning Patrick,

There could be a number of reasons why your drains are running slow. Do you know if it is surface water or foul drainage?

Bill · Answer

Hi,
Slow drains normally means a blockage in the pipework. You would need the line jetted and possible cctv camera to see if anything is still stuck in the pipework.

Mark · Answer

Depends has the drain just become slow running if so there could be a problem. Is it toilet or sink or bath?

Michael · Answer

A C.C.T.V survey will determine why your drains are slow running.
