Hi,
Warmer weather cometh and it's time to put the guttering back...
I have 4 downpipes.
One is blocked, but only served a 3m bit of flat roof and there's a gulley drain nearby (yes I already pay for rainwater down the drains).
Of the other 3, 2 are at the front of the house and one at one end of the rear - 3 corners basically.
I *thought* these were connected to the sewer, but a test with a hose shows they are not - and more annoyingly, that one is blocked and holed and spewing water below ground (below concrete).
I'm considering switching to just the two diagonally opposed downpipes. Gawd knows where they go, but they seem to run free.
For a hipped roof 11.6 x 8m (bungalow) are two downpipes diagonally opposite likely to cut the mustard? The guttering is 4.5" half round - though a lot had rusted away, and whilst I could use a deep section to replace it, I'd waste a fair amount of good guttering.
It would be unwelcome work at this stage to investigate the blocked drain - though I am tempted to buy a 40 quid 5m-leaded usb camera from ebay to make sure the other 2 drains go a reasonable distance from the foundations.
BTW - what is a resonable distance? I seem to recall 5m being mentioned somewhere as current standards, but should I worry if it was 2m, or 3m?
Cheers!
Tim
