Problems With Guttering System

[Metal Head]

Hi,

We had a crew in several weeks ago who came in to put in a water recyling tank and changed the configuration of the gutters to allow the water to drain into them. However, I now find that water is still lying in the gutters (either side of the v-shaped roof).

Is there any specific angle or fall that the gutters should be set at to allow the water to run away (btw I am in Melbourne)?. Am I also right in saying that the gutters should be square to the frame work (taking that is square to the ground!!). The reason I ask is that it can be seen from picture 4 that the gutter isn't square consequently I assume that all the water won't find it's way down the exit hole as is the case atm?.

Would it also be fair to say that the pipes from both gutters (in picture 3) should be on a slight angle rather than flat to allow the water to flow into the tank easier?.

Thanking those in advance of their reply.

Cheers

David,
the proof is in the pudding, if the water is lying in the gutters than obviously they haven't got it right. Usual fall is 1 in 200 and , yes, the bottom of the gutter should be level, front to back. Pipes should not be horizontal either, which is why the bends are 95 degrees rather than 90. Get them back to get it right. Also the close up of the end of the gutter looks pretty dodgy, looks like the stop end isn't fitted properly and that there's about half a tube of silicone in there.

Hi Mick,

Thanks for the reply and giving me some assurance that I thought I was correct. When you said that the joints are ninety five degrees are we just talking about storm water elbows, or other types of joints as well?.

David,
AFAIK all drainage fittings are 95 rather than 90 to allow for fall.
