We have had trouble with our bath water flowing out onto the path rather than soaking away. Have checked the inspection cover and that all seems clear so, do I assume something is creating a problem in the 2mtrs from pipe to inspection chamber?
Would love to have an idea before calling the drainage people.
You could invest in a set of drain rods which have been on offer for less than Â£7 in places like [b]QualitySave[/b].
These are flexible polypropylene rods and when screwed together will reach 10m - remember to keep twisting in a [b]clockwise[/b] direction so they don't unscrew. They will get round tight bends in drains, ideal for your problem if you have the right attachments.
Probably a blockage between the house and inspection chamber - at worst a collapsed drain.
To find out for sure the best bet is to get a camera down the drain alot of companies offer CCTV inspections - this will tell you exactly what's causing the problems.
I would, lift inspection chamber cover and run bath any water appearing in chamber ? no water or very little I would get some drain rods down to see if this'll clear the problem, if it doesn't you either get drain people out to assess - or start digging and check the drain yourself (which is the route I chose, I dug down and found a collapsed drain)
Always rod away from the house towards the chamber, never rod back up as all you'll do is compress the blockage and push it further back.
