Joining 125mm gutter to 112mm guttering
Bluemoon - 8/11/19 at 02:45 PM

HELP!

I have a problem: semi-detached house, I need to join the following guttering between my house and our neighbors:

1) OSMA Superline, half-round 125mm

to

2) Brett Martin Cast Iron style 112mm round style

OSMA or Brett Martin do not sell a 125mm to 112mm adapter and I can't seem to find a suitable one...

Any ideas? I want something that will work well and is not a total bodge.

I can't use two end stops without changing the neighbors' gutter fall as it's annoyingly draining to our side...

Cut a strip / short length (or two) and glue to the inside of the bigger size to make up the space and glue the smaller size on top of that.

There are glues for gutter / pipe that melt into the surface and form a permanent bond.

I'd 3d print an adapter in abs and solvent glue it on!!!

Here in Mexico that is illegal.
I would think it is so in the UK?

Don’t think it would be Illegal here they have a down pipe, in principle the gutter should be level or run down from the boundary. But being a good neighbour I wouldn’t do that without sorting out the fall with their permission... hence looking for alternatives.

I think the best approach might be to notch the wider gutter to fit in the smaller joining union of the small gutter?

Bond two end caps together and drill between them ?

Will the water flow from the smaller into the large, or other way round?

If small into large I would lay a small joiner in the bigger gutter and bond/glue (tigerseal?) in place. But if water flows the other way it will need to overcome a step of some description. Or get clever with some fibreglass? (though difficult to get a good bond to the plastic)

Certainly cannot be illegal for existing properties as every other street in Brighton/Hove has shared gutters, probably the same over the whole country. New builds would likely need their own system.

Many semi-detached houses were built from the start with the front and one side gutter running down to one corner and the rear and other side ones running down to the diagonally opposite corner, thus requiring only two gullies.

Some terraced houses may only have a downpipe every 3 or 4 houses along the row.

You probably won't find new houses built like that.

Well notched the gutter seems to be working well no leaks.. no glue to fail, and smooth flow without steps... time will tell if this works out long term..
