| Feb 24, 2017 at 9:34 | comment | added | Chris H | @AndyT for me that's a significant advantage, which is why I mentioned it (I have two water butts for this purpose alone, so to some extent I treat the drainage as an extra). I'm about 200km (150mi) SW of the OP, with a similar climate, but my rainfall is skewed a little more towards winter so I need to water the garden in summer, sometimes quite a lot. I'm assuming an unbroken pipe to the same drain in both cases, so you can add the level of the outlet. | |
| Feb 23, 2017 at 16:39 | comment | added | Chris H | @AndyT I was perhaps a little too brief. Assuming the water butt is already full to the outlet, and you add a constant depth of water to it, the head will be more for a higher outlet -- you're effectively lifting the drainable stored water up with more water. It would never shift water faster overall than taking it out the bottom, but the extra head would mean that the flow started faster, offsetting the loss of buffer. | |
