Intermittent Sewage smell in and outside house

[Laura-Jane Fox]

Hi all. I have been having intermittent sewage small for about 10 months now. It smells inside out kitchen and dining room(open plan) and outside down our drive and in back garden. I have had dyno rod out several times who have done 4 CCTVs, flushed the drains and general checks. To no avail. We have had a plumber inside to check traps and he replaced a few. Dyno rod did put some expanding tubes inside the pipes at the top of the drive (no where near the smell) when the 1st man came he said it looked like all the pipes had displaced but then they only fixed the end of the drive. We do not have a manhole according to dyno rod(it's not visible) as they have looked when doing the CCTV saying it runs straight to the mains. Severn Trent have check all the mains and these are ok... Please help as its driving me mad

Have you got an internal or external soil stack?

 

[Laura-Jane Fox]

External soil pipe

 

[Howsie]

Has the house been extended?

 

[Laura-Jane Fox]

Yes but before we moved in and before the smells. I thought I might also mention that the majority that we can see have manhole covers up out street. We just don't seem to have 1

 

[Dotty]

Pound to a pinch your extension is over your manhole.......

 

[Laura-Jane Fox]

From dyno rod looking through CCTV, they said they didn't think we had a manhole as it just runs straight to mains?

 

[Laura-Jane Fox]

They also ruled out any blockages as it all runs to the mains smoothly

 

[Dotty]

Wouldn't be they first time they've been wrong in my experience.

 

[Laura-Jane Fox]

O. Any ideas how I would find this out? Also if there is no blockage surely even if I have a manhole, that wouldn't b a problem

 

[Howsie]

And mine.

I would bet your extension sits on it. Lazy builder syndrome.

Where are your neighbours manhole's?

 

[Dotty]

Site plans pre extension.

You'll need to contact your local planning office.

 

[Laura-Jane Fox]

Theirs are on their drives and they have extensions

Do the drains all run to the front of the house to the road or does yours connect with a neighbour? As in shared drain? Might be worth a call to your local water management company to see if there's any history of problems in the area.

Also, not questioning the plumbers credibility or integrity but perhaps another visit from another plumber to double check all traps in the house.

We were told by dyno rod it looked like they all run to the front n that they don't join with anyone else's. yes I was thinking about another plumber

 

[Laura-Jane Fox]

I also have soak always if that makes a difference

 

[Laura-Jane Fox]

Any other help please? Really desperate

 

[Howsie]

A decent plumber is your answer. There are not that common unfortunately.

 

[Dotty]

One who knows how to carry out smoke tests.

 

[Sag]

Sorry I can't help but curious as to how much you've already spent with dyno rod & other plumber. Did it really need 4 CCTV inspections? I'd have thought they'd suss it on first attempt.

That's not the fella with the Marlborough reds btw.

 

[Laura-Jane Fox]

It's all under my house insurance

 

[Laura-Jane Fox]

What would be the idea of a smoke test

 

[Howsie]

To identify if/where your sewage stinks are escaping from.

 

[Sag]

Who are you insured with? I didn't think any/many insurance companies would pick up the bill for that.

 

[Laura-Jane Fox]

Barclays

 

[Laura-Jane Fox]

Any other ideas? Appreciate the help

 

[lame plumber]

simple check, bung in at driveway end, fill drain to road with fresh water till its full and check its water tight, may or may not be, may see water escaping if your lucky. if its water tight, may be a buried manhole cover, compare with neighbours, or could still be faulty traps., worse case neighbours drains through yor property? leaking but least likely

 

[Laura-Jane Fox]

Not our neighbours drains as they are all ok. Not 100% about the manhole but if there isn't a blockage as its draining to the mains fine as far as I know then it shouldn't matter if I can't see the manhole (obviously I would like to no if I have 1.) Severn Trent couldn't help with regards to the manhole

 

[Dotty]

As I said earlier. Go to your local planning office.

 

[Laura-Jane Fox]

I have tried to no avail

 

[Dotty]

In that case you need a plumber in to perform a smoke test.

 

[Laura-Jane Fox]

Ok thanku am going to get dyno rod to get one of their plumbers to come and look then I haven't got to pay

I'd be asking for a freebie since they've been out four times and come up with nothing. It's all being added to your claim, which is probably about a grand already by now at their rates.

 

[Laura-Jane Fox]

I'm only paying my excess though and was told it wouldn't really affect my premiums

 

[Howsie]

That's what they all say, but its lies.

 

[Laura-Jane Fox]

To be honest I'm not bothered. I just want the smell to go away

 

[Howsie]

Where do you live?

 

[Laura-Jane Fox]

Leicestershire

Update:
dyno rod done a smoke test today. Everything ok. Checked inside again. Pipe behind dishwasher was leaking a little and not on the wall properly (now sorted). He said that wouldn't be a problem.
PIG would say the smell happens in the drains and then comes out and inside thrrough the gaps.
They said they have no other iideas
does anyone else have any ideas? Thanks

 

[Laura-Jane Fox]

Update: dyno rod have detected that 2 soak always are connected to the main drains without traps. Well I detected the second. Not 100% the rest aren't but they quoted me £480 to do the 1 they said and house insurance won't cover it! Even though I didn't fit them
