60×80 shed, downpipe positioning

[Steevo]

Why not just use a deep flow folded metal gutter to increase capacity and be sure you’re covered?

Galv box gutter is all I will use nowadays for farm sheds. Not a fan of plastic at all as it seems to warp and sag.

Trimline gutter for insulated roof seems ok so far I think, and looks smarter too.

Putting up a 60' wide × 80' long shed. Using the deep profile plastic guttering.

Will I get away with the downpipes at one end of the 80' run, or do I need to position them half way along the shed so gutters only taking 40' each way of rain water?

I'd prefer the downpipes at the end, but would be pleased of any experience/ advice. Thanks

Go large on gutters and down pipes and add a few rain water harvesting tanks at the end of the down pipes and you are sorted for sprayer water

This is a 200mm gutter going into 160mm down pipes running to a rainwater harvesting filter and tanks (This is on a 140x75ft shed)

We can quote for any rainwater harvesting needs filters or tanks etc

Save starting a new thread. Does anyone know if it's possible to get a hopper head with a 160mm downpipe outlet?

8” deep flow gutters & 6” down pipes at one end of a 110’ span 75’ long. All fine when new but a bit like a woman, not as good when it all starts to sag. Now got steel gutters & extended the shed to 155’ still with one 6” down pipe at the end & its always coped so far.

You can definitely get them. Not sure if Toolstation don’t sell them

Have tried a few places and can only seem to get them with the 110mm outlet. It's for patching up an Atcost gutter outlet, and I don't think 110mm would suffice.

We put up an 80x60 last year, with downpipes at the end to collect the water. In a heavy shower the gutters cant cope.

How big

I actually bought that off of them a few months back, and it arrived and was for 110mm downpipes. They said the description was wrong on the website and took it back, said they couldn't get 160mm ones.

Perhaps the best option then would be to cut a short length of metal box gutter, fit a stopend on each end and drill it out for a 160mm top hat outlet.

I don’t bother with gutters just hang the roof sheets out 6 inch. Gutters and down pipes just cause problems and aren’t cheap nowadays. No drains to worry about either.

Anyone recommend a good online company where I could get some 170mm guttering and fittings and deliver it north Scotland ? Only need about 20m.

I looked up specs once of 170 deep flow the specs answer was 60ft length if at end or 120ft if in centre an idea to be in spec could be to have outlet 20ft from end?
I don't know if this was based on a M2 of roof area I was looking at a 60ft building so still comparable

Rightly or wrongly we've gone with 170mm deep flow, and putting downpipes half way along (80ft long shed). Taken cheapest option.

It won't cause an issue if it does overflow occasionally. Will see how it goes.

If we ever put a lean-to on side of building, then we could alter fall of gutter to fall either way and put fallpipe at each end.
