it gets worse!!

After my previous posts today the down stairs toilet was removed and a hole knocked in the wall to gain access to the stench pipe and then its found that the two plus gallons of builders waste and god knows what else is leaking around the bottom of the stench pipe where it disappears into the ground, Resulting in flooding under the floor etc, to me whats happened where its been rodded over the last week or so my various plumbers etc theyve rammed it and cracked it under ground. No this means the whole floor has to come up and the two year old bathroom took out downstairs all the under floor heating etc replaced There was alot of rubble down around the stench pipe from the work carried out inc bricks and other large items. I went upstairs to discover todays plumber ramming down a rod with a metal spike on it!! Telling me after the stench pipes iron when its asbestos and that the pipe under the floor is clay. All in all im getting wellwith it.

Perhaps you ought to call in a drainage firm like my son who specialises in no dig repairs
... drain lining as it is commonly known..

That would be the way I'd go too.

Hpw do these work? Basically ive got a stench pipe that has a toilet at the top of it where it disappears into the ground. it is leaking around or under ground the pipe is blocked as its got about 8 ft of water sat in it looking down from the top The pipe then i presume has a 90 degree bend this is where its blocked/cracked

a good drainage firm to clear the blockage and line the original! top marks

In this case one would first attempt clear the blockage using HPW Jetting equipment,
It seems to me to be an issue with the rest bend which is the fitting that is designed to
connect the stack to the drain, quite often they break which can often be attributed to downwards movement of the stack.
When they break they generally move to one side leaving a sharp offsett instead of a smooth transition from the vertical stack to the horizontal drain, which causes paper to snag and precipitate a blockage,

In this case I would Jet upstream from the manhole towards the blockage, if it did not clear immediately, I would take a look using a Drain Camera in the (by now clean) drain this should reveal what is causing the blockage,

In similar circumstances I have seen objects such as a shoe, a milk bottle, a brick,

I wont go on about it but I have once taken a double bed out of a manhole, another
time a complete edition of the local free news paper consisting of several wet bundles
of unbelievably heavy paper.
Whatever it is that is causing the blockage 9 times of 10 can be removed without
digging,

I would then CCTV it again to check if it could be lined effectively,
If it is broken and more the say 20% offsett then you probably would be better off
digging it up,

On the other hand a Spot Lining can for example easily accommodate a transition in pipe size from 150mm to 100mm probably better than a purpose made fitting, so a small offsett in a rest bend should not be a problem.
The kit needed to install a Spot Line comes to £600.00 or so, but it does require a degree of expertise on the part of the plumber to achieve a successful installation,

Well today my blocked stench pipe was sorted thankfully, by jetting and now thankfully seems ok the amount of "debris" that came out was unbelievable and thankfully it doesnt appear to have been cracked

Hi Muscle750, So what was the builder's explanation for all that rubbish in the soil?

I take it that it was cleared at his expense?
