Another question about water butts I'm afraid!
Our builder has voiced concerns about having the water butt on our decking. He said that even with a rain diverter, if we have torrential rain the diverter may not stop the water butt overflowing and this of course isn't ideal if the butt is standing on decking. Can torrential rain really cause this problem with a rain diverter?
On a side note, I've also read that water butt lids should be a tight fit with no gaps, to stop bugs getting in and breeding. Our water butt has four small holes (designed, not caused by damage) in the lid, all about 5mm wide. Should I block these with something like silicone sealant?
This water butt feels like it's more hassle than it's worth...
