sewer

When the macerator flushes it causes the water in the traps for the sink and washing machine to spyhon out. I was think of installing something like a anti-syphon p trap for the washing machine and sink. The macerator which I have on the 1st floor. I saw mentions of an AAV, but not sure if I...

Looking to figure out how I can join these to the drainage that goes to the sewer. I guess I need to get a drainage trap like this , but not sure what else is needed to join the black pipe (shower) and grey pipe (sink and diswasher) The drainage pipe goes down into an elbow into the sewer...

Hello. So currently I am excavating the foundations for a cavity wall garden office. Unfortunately my drain pipe runs at an awkward angle at the corner of where my foundations would be. My initial thought was to excavate the foundations deeper and pour the concrete below the pipe, and then...

Hi I have this issue in my house where the main bathroom upstairs, and the downstairs toilet, both have a strange unpleasant smell, I'm assuming sewer-y. The en-suite is fine, although the previous owners did some dodgy renovation and behind the vanity unit is a massive hole in the wall into the...

I recently had a drain survey done as a soak away pipe at the front of the house is visibly broken and requires repair. As the house was built in the 60s I thought it may be beneficial to check out the whole system. There are no other obvious problems. The men who came to do the drain survey...

We are close to exchange on a house constructed in the 1930s and the searches indicated that a 225mm foul sewer is within the property boundary running longitudinally underneath the house. There is another sewer at the end of the garden. Search also revealed a water main (in blue, size unknown)...

Hi, I'm trying to self plan a rear extension to our semi-detached house, and hoping someone could give some feedback on my drainage plan. Currently the rain water pipe (RWP), and soil vent pipe (SVP) connect to a manhole at the rear of the property. This is a private drain, that then runs into...

Hello, Hoping someone might be able to help with our drain connection idea. We currently have a private drain that passes behind our house over to our neighbours garden that is marked on the Thames Water plans. From our neighbours garden it then goes into the main sewer. We'd like to do a rear...

Hello. I'm looking for some advice about a neighbour's outbuilding. The neighbour has built an outbuilding (which is their right of course) but have also connected a soil pipe from the outbuilding all the way down the garden to then join the sewerage system on a shared passageway. The trench...

I am replacing a traditional toilet with a Grohe frame and I need to replace the existing waste connection (see pic below) with the one that comes with the Grohe frame. The connector goes down into the concrete floor and I have no visibility of where it goes/ how it connects. If I just yank it...

Hi folks I have this buchan trap in my garden, the area I want to monoblock. I'd like to replace the concrete lid with something more aesthetically pleasing. But can't seem to find anything. I know it needs to be vented etc. The shaft size is 360x240 (inside measurements). Could I corbel...

I recently had the manhole cover off my drain as there was a smell of blocked drains, turned out to be next door But I did notice what looks like a small blockage at the bottom, it almost looks like cement / concrete I’ve never looked down a sewer so not sure what it should look like! Also...

Hi all, long time guest user but first post here. We are currently having a single storey extension built. There are various private and public sewers that run under the extension with a man hole having been removed. The next obstacle is bridging this pipework for the foundations, because of...

Hello everyone, We have a build over agreement from our water utilities supplier as we're building near a large sewer pipe that runs between our house and neighbour. Our neighbour is difficult and asking to see the agreement. I don't see why as it's between us and the utility provider. Any...

Hi guys, So I’m desperately after some advice! Since moving into our house a few years ago the sewer pipes always get blocked. We’ve had professionals clean them but they still clog up after a few months. What I believe to be happening is my waste pipes are not on a steep enough gradient and/or...

Hi folks, anyone know what this is - it’s made of cast iron? There’s one at the boundary of a lot of properties in Aberdeen.(which all seem to have been built in the mid 1960s). I think it might be a sewer vent but would like confirmation as we’re widening the opening to our driveway. Thanks

Hi all, Looking for advice regarding an intermittent sewer/drain smell in our kitchen that we can't get rid of please! We have a 12 year old townhouse and over the last few weeks have had an intermittent smell in the kitchen coming from the sink and the part open top back of the kitchen lower...

I have just started excavating part of my lawn for a patio and have discovered a manually perforated grey plastic pipe that leads into the side of the main brick built surface water manhole. I'm guessing first of all that this breaks every regulation in the book, if so how do I remediate this...
