Discuss Aco drainage - change direction in the DIY Plumbing How-To Guides area at PlumbersForums.net

I have 3m of ACO drainage in my garden - they drain to the left and I want to change the fall so they drain to the right

I do not want to take them out and adjust the fall by re-laying them as it will cause too much disruption. I can access the end though to connect a new outlet.

I figure though that all I need to do is change the 'floor' so the slope is going the opposite way

Best I can thing of is to get some half round gutter pipe and put it in at a slope so when the water hits it just goes the other way. I could put some shingle underneath to support and then sue external sealant to stop water going underneath through the edges.

It doesn't have to look pretty as it will be covered by the grill.

Anyone have a better idea?
