Drain off to water butt or drain?

Dan-Dan

Hi

Taking down an outbuilding that has the downpipe from roofline guttering routed over it and into a water butt, so i need to route the downpipe again...


Underneath the outbuildings floor is the floor drain , and the old occupier had decided before blocking it off with the flooring to fill it with a massive ball of expanding foam

I plan to deck this area of solid concrete (it will be under a garden canopy) should i continue to route into a water butt , or should i somehow (??) hack away the expanding foam and route into the drain and build decking around the grate ?

Cheers

Sorry , i should add of course that the outbuilding is attached to the main houe (width of back wall)

If you drain the roof to a water butt, you will still need a pipe to the drainage or soakaway to drain the overflow from the butt. In the winter wet season the butt will always be at overflowing.

hmm , thanks , so in reality , even though the drain is literally adjacent to the back wall , i should still route to it ? it just felt like the `right` thing to do , not to use it if i could help it , just to keep water away from the house as much as possible

Any thoughts on the best way to remove expanding foam without blocking this new , uncovered drain?!

You used to be able to get a product to eat/dissolve the foam.
