rainwater butts again
Hello, - there have been several posts about water butts recently.
How big does it need to be & what if it overflows ? Are they easy to plumb in to the downpipe ? Thanks KK |

writes Hello, - there have been several posts about water butts recently. How big does it need to be Depends on how much you want to consume. In general I'd say the bigger/more of them the better. & what if it overflows ? Are they easy to plumb in to the downpipe ? If you use the special diverters you can get for downpipes, then once it is full it doesn't fill up anymore and the water just goes straight down the downpipe. -- Chris French |

No, there are no moving parts, as long as you position it correctly when the butt is full the outlet hole is full of water so the water rises in the diverter and so flows back into the down pipe. The water companies sell, at discounted rate, butts complete with diverters, stands and some even a watering can. Simply look at your water companies web site. -- Please do not reply to this Email address, as all Emails are deleted before opened. |

Does it have some kind of float valve. I have only ever used the original models which had a separate overflow back into the downpipe. They work because when water flows in the downpipe, surface tension ensures it flows over the inner surface, not as a stream down the centre of the void, IYSWIM. The diverter has a shallow annular 'gutter' arrangement on the inside, which intercepts this surface flow and diverts it off into the butt. When the butt is full, the water backs up the connecting pipe and overflows the shallow internal 'gutter' and then on down the downpipe. For the system to work properly, the diverter on the downpipe _must_ be at _exactly_ the same level as the surface of the water in the butt when the latter is full. The easiest way to get it right is to fit the diverter in the downpipe fractionally too high (say an inch or so, but no more) and then raise the level of the butt with packing such as concrete slabs, old slates etc. to get the level just right. For the OP, I would choose the biggest butt you can get or that will fit the space available. If you can, get several butts and link them together as near to the bottom as you can (butt suppliers do linking kits). Linking them in that way means they all fill to the same level and you only need one outlet tap.

Chris - thanks for this , but does plumbing them together like this mean
that you get low pressure ? Is it better to fill butt1 and overflow to butt2 etc ? KK For the OP, I would choose the biggest butt you can get or that will fit the space available.

It makes no difference to the pressure, which is dependent on the depth of water in the butt, regardless of how you link them or how many. You will have to cut additional holes in order to link them as I showed. But you would have to do that anyway however you link them and it's no problem if you have the appropriate drill. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

For the OP, I would choose the biggest butt you can get or that will
fit the space available. If you can, get several butts and link them together as near to the bottom as you can (butt suppliers do linking kits). Linking them in that way means they all fill to the same level and you only need one outlet tap. In fact you can link together several butts that do not have low-level linking kits, even butts that do not have ANY linking kits! You just link them via their taps. I currently have three one hundred litre butts linked this way. with more on the way. The way they make these small butts (I'm talking about the "Space-Sava" type) means the linking cutouts are at the top, for overflow use, not at the bottom as you get with the bigger sizes which have a true linking capability. But linked via their taps with some hose and some three-way adapters, and of course you have to leave the taps open for this to work, they will all fill up equally with the rain only flowing into one of them. This way you can add further small butts as the need arises. As they are not deep from front to back they can line up against a wall. Needless to say you have to turn all the taps to OFF before removing this makeshift linking kit from and filling watering cans etc from one of the taps. Or use inline taps as well. The only downside I can see is that the tap flow rate is slow compared to an overflow or linking kit, which seem to use 1" hose and have large apertures, so in a really serious downpour the first butt might still fill and overflow before filling its companion butts. The answer is to use the overflow connections to link the butts as well so any overflow fills the other butts before going anywhere else- then the last butt in the chain can have an overflow that leads somewhere else. It is surprising what combinations and configurations you can come up with if you draw these things out on paper. Like for example an external water level indicator that shows the level inside all the linked water butts. But it seems I'm spending quite a lot on hose fittings..... -- VX (remove alcohol for email) |

Still thinking. if the butt fills from the top, cut a hole on the side of the barrell at the very top and plumb it back in to the downpipe. Water will drain in to the butt and any excess siphon off the side. Maybe not that pretty but should work. rob |

YEs, that would work but the problem is my favoured "buttsite" is too
far from the downpipe, with a shed door in the way. If it was next to the downpipe I would just use the usual downpipe fitting (with internal "saucer"). |
