sewer

Hi, new poster hoping someone might be able to help me with an issue that has me at the end of my tether! For almost a year we have been experiencing intermittent sewer gas smell in our house. 2 years ago we had a rear extension done, including a downstairs WC, which involved re-routing some of...

Hi - I am applying for a build over agreement with Thames Water to build over a sewer. They require "Existing" and "Proposed": a) Cross-sectional foundation plan b) Ground floor plans How do people usually determine the existing foundation plan? Do you actually dig down until you see the...

Hi I've recently had my raised front garden taken out so I can make extra car parking space in the front garden. The inspection chamber (see photos) was originally 3 or 4 brick courses high, the biscuit was removed and the courses removed. The biscuit was replaced and is now as low as it can...

Hi, I am looking at building an extension at the back of our house but the area where we would build has the public sewer that runs along the back of the terrace of houses. At the back of my house it’s very close to the surface and then goes down the side of our end terrace house to the road...

Good Evening all, I have started to have a go at replacing a cracked Gully pot, and having exposed the pipework want to take a pause and just double check my next steps are going to be OK. So, for reference: This picture shows: Left hand small pipe - Something dodgily put a drain run that...

Ok, here is a head scratcher. I have a 3 storey house, pre 1937. To the rear is a lawn on the left and a patio on the right. The rear lane is 3m lower than the lawn so a pathway with steps down to lane level passes between the patio and the lawn. According to deeds the drain runs under this...

Can i put a step in a drain run? Down obviously not up, i would assume it needs to be rod-able from both directions but would it work? I have a reinforced ground beam to get over. The invert of the drain is the same height at the middle of the ground beam so i was proposing 110mm pipe over the...

Hi all. Thanks for your time. We have a conservatory of around 5.45m x 2.5m at the back of our mid-terraced house. We are hoping to replace it with an extension stretching back a bit more (to 3.7m). However, the absence of a manhole/drain cover in our back garden, and the presence of them in my...

I'm planning on building a garden office in place of the current shed. It will be at the back of the garden, ~ 40 metres from the house, and have a toilet, electric shower and washbasin. From what I've gathered, for water supply I can use 25mm blue MDPE and this needs to be buried underground...

Hi, I appreciate there are several posts relating to foundations but each case is different so was hoping for some advice. I'm trying to build over a 900m diameter sewer with invert level 2.7m below ground level in Harrow, Middlesex. The max distance that I have from edge of the sewer to the...

Hello, I am in the process of buying a house which has an old septic tank. The vendor doesn't know anything about it at all (so older than the 15yrs they have lived there), and they don't know where it drains to. They claim it works without problem, and is emptied once a year. I will be...

I purchased a home a few months ago. Unfortunately I found a truly foul smell in the bathroom, at least after running any water. A bit of nasal investigation revealed that this smell was (at least partially) coming from the bath u-trap, clearly escaping sewer gas. Unfortunately I couldn't find...

Hi all, I'm looking at buying a house with a diagonal crack, ~1/4" up the external wall of the passageway between the 2 terraces. The surveyor thought it was historic so shouldn't be an issue for mortgage. But I do want to tidy it up for resaleability, and before that get the leak fixed...
