Existing conservatory rainwater pipe - terminates into groudn?!

Anonymous user 28/02/2024 - 3.58 PM

Hi, We've recently moved into a property with a decent sized (raised floor) conservatory. Next to the conservatory is a decking area, which we are currently having replaced as it was in dire need of complete replacement. Whilst the old decking was being removed we've discovered that the rainwater downpipe running form the conservatory guttering just terminates 'open ended' a couple of inches above ground level (i.e it doesn't terminate into any below ground drainage point) - surely this isn't right?! There is a drainage point next to the where the conservatory rainwater downpipe terminates but this is for the kitchen sink/dishwasher wastewater, I'd therefore assume we couldn't terminate the conservatory rainwater into this drain? What options do we have to ensure the rainwater from the conservatory terminates correctly? and in a fashion that isn't likely to cause any damage to the structure of our house.

Are you a tradesperson and able to answer this question?

You can have rain water just running onto the ground but it tends to be running into an aco drain which discharges the water further away from the home usually around 4/5 feet or it runs into a drain to avoid any damp problems with your home. It shouldn’t be into the foul drain that your waste pipes go into as they connect to your soil drains underground and shouldn’t cross contaminate. As this happening below your decking you could install an aco drain to carry the water away and it would be hidden from sight as they are not the prettiest of drains to look at, I hope this helps

You can use the same drain for rain water and kitchen/bathroom Just letting it drain into the ground WILL cause damage to your foundation I recommend this be fixed asap Good luck LMC BUILDING SERVICES

You can only use a foul drain for discharging surface water if you have licence to do so from the water authority & on mains drainage. I hope that clarifies.

Hi No this isn’t right, the downpipe would need to terminate into a drain or soak away as the volume of water concentrated from the guttering/down pipe will effect the ground, this is correct method.
