Levelling Compound in Drain !

[Spinny]

So our flooring contractor has managed to pour floor levelling compound down one of our drains !

We have a rain water drain that is completely blocked at the u-bend.

Other parts of the drain had deposits.

 

Is there any way we might be able to unblock the rain water drain ? Some kind of solvent or acid ?

 

Plumber cleared some from the vertical part of the drain using a very long drill bit, but clearly won't go around a bend.

 

Drain pipe is clay. Levelling compound is Bostik C530 which has fibre reinforcement.

Keep it wet, keep the u bend completely full, if you let the air get to it it will harden. 
get a piece of 15 mm hep 2 pipe and ram it around the trap, back and forth 

take detailed timing of how long this takes and charge the flooring contractor 

 

you really are attracting some muppets.

Here is a piece the plumber drilled out of the pipe vertical - see photo.

You can see the reinforcing fibres in the leveller, and you can see some sticking out in the middle photo above.

 

I doubt the 15mm hep 2 pipe is going to do anything TBH. The plumber was having to drill bits out.

That said I did get some bits out of the main drain pipe by ramming some 32mm MDPE up and down the pipe - but that was straight pipe and only congealed pieces stuck to the bottom of the pipe.

Plumber was of the opinion the drain would have to be replaced - but once you start on clay pipe that is 90 years old you are likely to end up replacing the lot.

 

I have just about had enough now. The last 'customer' of my original builder was having him do a barn conversion - 'customer' died of a heart attack during the build. If I stop posting you'll know I've gone the same way.

Are you saying this was poured down the drain as a way to clean up at the end of the day and dispose of the excess goop?

 

If so......................what a cock.

Replacement seems likely, but clay pipes are pretty robust so it will likely only be a localised replacement. At least they didn't tip it down an internal drain...

A bit bleak :)

 

I'm sure the end result will be worth it!

I can only presume so as I didin't see it occur. There were two people, the older experienced guy was in the kitchen pouring and spreading the leveller, and then a monosyllabic youngster preparing tubs outside with water from the outside tap.

 

Work was done at the start of an extended dry spell. Some 7-10 days later we had heavy rain and SWMBO went to empty some waste water down the drain. Noticed the water level was very high near the top of the drain. Opened the main chamber shared with the neighbour but on our property and u-bend water was also high with stick test showing there was something in the bottom of the u-bend there too. Week later plumber finished fitting our water softener and so we investigated further with the help of his water vaccuum. Found leveller blocking the rainwater drain and stuck to bottom of main drain pipe run and in bottom of main drain u-bend.

 

Plumber explained and demonstrated how old clay type drain risers above the u-bend are actually permeable to water. So the drain doesn't necessarily completely overflow, water leaks out into the surrounding soil/ground through the sides. If you suck the water out of it, it refills as water from the adjacent soil/ground drains back into the riser again.

 

I called the manufacturer Bostik in search of some kind of solvent/acid that might attack the leveller but not the clay - he hasn't called back.

It might not be terrible hard If it is cleaning of tools slops then it will have been very wet and that makes it weak.

 

It is total ignorance... thinking a drain is a magic thing where stuff goes away.

Yes the culprit should pay for a solution.

I wouldn't want them bodging a half- hearted improvement. It needs a groundworker who doesn’t mind old-fashioned spade work.

£1,000 deduction, some released if it turns out to be easier.

I spent yesterday giving them merry hell because after 2 months they still couldn't tell me when they were going to finish levelling the kitchen even though I have told them from the start it has to be done before W/B 18th May as that is when the kitchen is being delivered and fitted.

 

12 days ago they told me they couldn't do the utility, only the kitchen, 9 days ago they told me they couldn't come last week and hadn't scheduled this week yet. I told them very clearly once again that I have a kitchen fit on 18th, if it is missed, it will be months before another slot is possible. The kitchen floor needs final prep, top coat, hardening time, checking for level and flatness, time to do any final remediation. Therefore must be done early this week. Their 'scheduler' then failed to schedule my job in, went on leave, then took another day off because his kid was sick. Then was told it was 'likely' they would come on Thursday i.e. at 5 to midnight.

 

They are supposed to have a good local reputation and are an Amtico premier partner (doubtless just sales volume based).

 

Not suprisingly I have lost all confidence in them, but with tens of thousands of kitchen stuff arriving next week I have no choice to sack them now. Pray for me.
