Gutter & Down pipe - Is this OK?

[eastender3]

Hi Folks,

This photo is back of the house.
In the event of a heavy rainfall, my guttering overflows through a hole in a soffit at the back of the house. I am wondering the down pipe arrangement on my side of the property may be carrying too much water for me and my neighbor, who has a kitchen extension and his guttering is on the right as well his chimney pipe, all coming to my down pipe. Is this normal? His house is end terraced.

I moved in to this property five years ago and changed the old timber glazing with a french balcony door. The neighbor thinks it's perfectly ok for this kind of arrangement. He hasn't go a downpipe in his back yard.

Just which part of the guttering is overflowing; on the section attached to the neighbours kitchen, or the guttering above that. Have you checked for blockages, and have you been up there whilst it's been raining.

The left part, my side of the guttering, there is a hole in the soffit, the water sprouts from there. There is no blockage. No I have not been up there while there is a downpour.

So I'd be right (just clarify things) that the neighbours extension is a red herring, as it's the rain comming off the roof, and going into the gutter on your property that's causing the issue. And would I be right in thinking that the downpipe on your property also catches the rain from your neighbours roof. If that's the case, then it could well be that the rainstorms we have are too much for the lower gutter to handle, and you might need to see if you can continue that upper pipe down to the drain in a continuous piece. Alternatively, you could upgrade your lower gutter that's overflowing, to a highflow gutter.

Thanks for the reply.
Can you please explain what you mean by 'upper pipe down to the drain in a continuous piece' do you mean the pipe coming down from the roof of the neighbour's house going directly to my down pipe? and what is a highflow gutter?

If it not blocked, then you probably have too much water concentrating in one place at the outlet, rather than too much water per-se.

Extend the downpipe vertically to a running outlet in the upper gutter, then have the neighbours gutter branching in to the downpipe just as it is now.

Or take the stop-end off your gutter, put a tennis ball in the outlet, and then all the water will run onto his roof and then drain down into his gutter more smoothly, and then down the spout

A high flow (also known as a deep flow) gutter, is designed to handle a greater amount of water. And maybe this is a better idea to handle the disharge off of the roof, rather than trying to get the roof run off down to the drain in one go.

There isn't any need for that upstairs pipe to continue down the tiles and into the outlet. People do it this way to avoid spray/overflow but the flat roof is there to take that. Everything is being forced into that outlet.

The neighbor does not want any water to run on his gutter, as he does not have a gutter drain but a waterbutt to collect water. He is suggesting I fit two downpipe, extra 1 to my existing downpipe but it will look unsightly.

Replacing the gutter with a deep one, will be time consuming and expensive, and no has fitted them in our back yard.

Is it better to have the roof pipe coming down directly to the downpipe? Sorry I'm not too technical and prefer a graph/picture for remedy.

Thanks.

I don't understand none of that.

I think you need to get a roofer to have a look at the job.

Cheers. That's finished the patio quite nicely.

I just love those, not sure what it is till it comes out of the oven recipies, and when you're not even sure of the quantities, well the exitement really gets overwhelming.
