    Conservatory drainage issue

    Hi, Our conservatory is leaking and its proving a challenge to figure out where its coming from. Where the external wall meets the conservatory there is an aluminum drainage channel. It seems to have a join there which I believe is where the leak is happening so I want to fix this first. I'm...

    New WC - Does it need a stack/SVP/AAV or can it go direct out to manhole?

    Please help, urgent! First post here, hoping someone can advise. We're planning a new WC in a garage, attached simplified sketch shows the plan. A builder we've been talking to has suggested a 110mm connection leading directly from the WC through the slab, then changing direction slightly to...

    Drain survey results query - money grab?

    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...

    Filled-in gully just below DPC?

    Hi everyone, just looking for a second opinion on our filled-in gully! We recently found a broken drain below the gully outside the kitchen of our 1910 house (which the sink and washing machine drain into, so this had just been pouring into the ground for who knows how long!). We have just had...

    Diagonal Drain in footing

    Hi everyone, Completed the dig on a 3m single-storey extension today and came across a drain that runs a way we weren’t expecting. Seems to serve as a rainwater waste but not too sure if that’s all it is as there’s another clay pipe behind it that seems to run down (done my best to draw it in...

    Help Explain Gutters and Downspouts

    Drainage on a porcelain patio

    Hi all, about to start a new patio project, approx 30m2 in size, I've been thinking about drainage, and the most serious conclusion I've come to, is that I install an ACO drain up against the rear wall of the property, connected to the fresh water drain that the gutter downpipe feeds into. Are...

    Is it Ok to put a raised sleeper bed here?

    I’m thinking of making a sleeper bed in this space in front of the window, on a paved driveway. There is an ACO drain around the perimeter and I would put the bed within that (not on top), and line it with geotextile so soil doesnt wash out. There is a basement below the window. Could this cause...
