Sewage smell all over house

[CupcakeGirl1]

I am writing in desperation and hoping one of you lovely people can give me a steer.

In April, I had a new kitchen installed. No significant change to layout but the plumbing under the sink was completwly redone as apparently it was a mess. 2 new radiators added to the room.

We were on holiday when kitchen was done. When we came home, couple of days later, we noticed a sewage smell in house. Specifically, in hall/next to cloackroom toilet which happens to be near kitchen.

We had someone out to jet the pipes - no difference. We got the kitchen plumber back and he found the source....there was raw seawge under the house as a result of a failure in the cloackroom toilet. I was relieved at this point. We put down 30l of disinfectant. However, fast forward 3 weeks and the smell is back again. Its bad. It comes up almost every drain in the house. Makes me feel sick and I'm sure its unhealthy. It literally spreads through the whole house. I can smell it as i sit here in bed typing this.

Ive asked kitchen plumber about it and hes not wanting to come back out as hes never seen this before and doesnt know what the problem is.

Does anyone have any ideas on what. could be happening?

Thanks in advance

Hi OP, what do you mean by failure of the cloakroom toilet? Do you mean the toilet is blocked?

Is it a collapsed drain from the toilet? Have any walls been built over the drain run in the past such as extensions that might have damaged the drainage pipe? First thing is to establish where the public shared drains end, yours start and where the drain run is. Usually toilet drainage is out an external wall, is that the case with you? Really sorry to hear that you have this problem

I think you need a drainage company to put a camera down to see what's happening. Your water/sewerage company may offer this service but it's not free. Having suffered many drainage problems in various homes, you have my sympathy.

I would get a company in, you want to be sure what the issue is at the end of the day rather than guessing and inadvertently costing yourself more money in the process of it

I bet the sewer pipe has collapsed. This happened to us a while ago - we had raw sewage coming up through the cellar floor. It absolutely stank. A chap came round from the insurance company and said - bafflingly - he couldn't smell anything (while I was trying not to vomit). Luckily (!) the 'residue' was tested and found to contain faecal matter.

Hi everyone, thanks for all your replies.

I'm still in same situation. Smell is unbearable - only a couple of rooms in the house that are smell free. Managed to get a specialist drains company out and they said nothing obviously wrong under the little toilet. The accessibility to under floor areas is so poor so we are essentially going to have to lift every floor and carpet until it becomes apparent what problem is.

I find it hard to believe that all of a sudden, i will have had not 1 (the sewage leak on the floor) but 2 malfunctions in the plumbing in my house.....whats the chance of that.

I know there are some real problems in the world. This shouldnt be consuming my thoughts in the way that it is but I'm embarassed to admit how down this is making me feel. I guess my buggest fear is that the source of the problem cannoy be founx :(

Does anyone else have a similar story with a poeotive outcome? X

So many typos! Woops!

A friend of mine had a sewage smell in their house for a long time and eventually found that the pipes for her dishwasher were rubbing against something under the kitchen floor. The water was leaking out of the pipe and sitting stagnant under the kitchen floor.
