Gutter into soil pipe

[Jodge]

Hi, advice needed please.

We live in a 1700’s property which has a combined drainage system where all waste and surface water (guttering etc.) feeds into the same drain.

The outside pipe work is carnage and I’m trying to tidy up. We have a soil and a guttering down pipe that run (almost) parallel, but the guttering down pipe has a couple of tight, basically right angle, corners to work around the waste pipe and to avoid the bathroom window, and often gets blocked. Both pipes ultimately feed into the same drainage system, but the gutter down pipe just runs into a concrete gulley which runs onto the patio and into the drain from the kitchen waste (I told you it was a mess!). There is no way to get a vertical gutter down pipe down, so my question is could I feed the gutter straight into the side of the soil pipe? I know this isn’t ideal, but it seems the best solution to me!

Any advice would be appreciated.

It's not ideal, as you really need the vent pipe to be clear of the eaves before it's open to atmosphere, there would be a risk of the drainage system venting via the rainwater outlet, under the eaves and into the loft space.

Can you get a photo of what's there currently, might be able to offer another workaround.

That soil pipe, and where it vents at the very top, is very close to that window and if it was ever allowed - it would not be allowed now.

Agreed Harry, my plan is to extend it

That would do no good at all with fall pipe connected it will vent out of gutter outlet.
Also that's a asbestos soil pipe unless your going to change it completely I wouldn't be touching it.

Cheers, always speaks a 1000 words. You've a right lashup these, mix of materials and reducing of downpipe diameter wont help matters. What I'd do, is replace the rainwater downpipe, entirely with plastic, and use 4x Offset bends to make one smooth dogleg round the soil pipe. Unless there's large volumes of detritus going down it from the roof, it should then be unlikely to block.

As Exedon has pointed out, that soil pipe looks like Asbestos Cement, and whilst the vent position is not ideal, I wouldn't touch unless you're going to remove all of it.
