Filters (by sarah)

Finially filters have been fitted on the Mills water supply which being fed from a spring through cracked pipes just happens to be full of stuff like e-coli. There is now a partical filter and a UV tube for killing off the bugs. The UV tube will have to be replaced about once a year I don't know how often the partical filter will need to be changed - but still this now means the waters safe to drink 🙂

This is a great relief when dealing with a two year old who loves water 🙂 They made sure especiallly that the bathrooms water supply was after the filter too.

Re the wriggly monsters I found in the cats water (you can read about that here it turns out Barbara gets the cats water from the water butt outside so no wonder it was full of mosquito lavea!

Damp Flags (by sarah)

Yesturaday the Rainbow people for the Mill came and said pretty much the same as was said of the Bakery - its naturally damp the amount of moisture goes up everytime it rains so the buildings at pre-flood levels.

Al asked about the 'long-term' solution and it would be taking up the flag stones and putting a layer undernieth but that isn't going to happen so for now its just getting carpets back in and rugs back down.

Unfortunatly the mill is basically sitting on a spring in the front part by the front door and when the water table rises it comes threw the floor! The water table is exceptionally high still and the guy showed us the visible damp patches on the stones - 'you can feel the damp with your fingers!' he told us demonstrating 🙁

The Disicated Mouse (by sarah)

The Rainbow people came again on Tuesday and pronounced that we were wetter than the previous week and therefore the property though very damp is naturally that way and they have returned the building to pre-flood levels. This ment they removed all the fans and dehumidifiers and will be signing us off so that the builders can begin their work.

However they did warn us that any floor covering we put down will go moulding in about a year and have suggested various things like ceramic tiles and waterproof layers - flag stones would apparently be the best as they would allow everything to 'breath' properlly. I think that what will probably happen is that a water proof layer will be painted onto the floor again even though that just means all the moisture will just go round it into the wall cuasing problems with plaster - sigh.

We really wish we had some spar cash so that we could sort it all out properlly once and for all but I dont think thats going to happen for a while yet.

We also found a little shrivelled mummyfied mouse corpse that had been dried out by the dehumidifier - in fact it was pretty much under the machine - I really wish I had a working camera as it was a photo oppertunity I'll probably never have again - gross but interesting - sigh I'm not sure that artist and scientist is such a good mix somethimes!

Big Voltmeter (by alaric)

My mate Seth brought me back a lovely big AC voltmeter from India, where the power distribution systems tend to reflect an earlier, more exciting, time where things arced and crackled, and everything was made of Bakelite.

Anyway, it's meant to mount on a panel, and the rear of it just has two exposed screw terminals. So I had to do a bit of work to make it usable.

Firstly, I obtained some crimp terminals - a nice set with eighteen different kinds, including rings, spades (male and female), forks, and butt splices in three different sizes.

Anyway, I really wanted it for the ring terminals, which would securely attach to the screws on the back of the voltmeter. So upon returning to home, I went to Maplin and obtained a large enough box, then spent a pleasant hour or so in the workshop with my father in law drilling holes in the box so that I could mount the voltemeter on it. We also scraped away some paint from the inside of the mounting holes, exposing the bare metal, so that I could attach another ring crimp terminal to the mounting bolt as an earth connection. Better safe than sorry!

The end result is a nice box with the voltmeter mounted on it, with no exposed live metalwork, and a standard mains plug on the other end so it can monitor my mains voltage. This is a pretty useful tool, since we do get power cuts and brownouts and so on quite often out here, and the lights often change brightness at random...

As I write, it's reading a bit over 230v, while earlier, it was reading more like 225v. At some point I'll ask Sarah to turn the shower on (our biggest load) and we'll see how much the voltage drops - because I know the lights usually dim when the shower comes on 🙂

Backup Power (by alaric)

As I have mentioned before, we have a petrol genset that we use to keep things going during our frequent power cuts. Immediately after the flood, too, when we had to shut down the house power since one of the outlets was submerged, I ran the computers off of the genset.

However, it is a pain to have to run the nice cable I made around the house, reach behind a filing cabinet to unplug the UPS that feeds the computers from the wall and plug it into the generator cable, unplug the fridge freezer, stretch cables about, etc...

So the logical next step would be to fit a second consumer unit, move the 5A lighting circuit over to it, and run a 15A circuit to a few strategically placed sockets around the house - where fridges and freezers are likely to ever be, and of course, up in the office where the computers live, and where the incoming phone lines are (where the ADSL router goes).

This consumer unit can run from a single 30A fuse in the main consumer unit (the slot currently taken by the lighting circuit will do nicely), but via a pair of 32A IEC 60309 connectors. The circuit from the main consumer unit would come out via a female socket, and the feed into the new consumer unit via a male socket.

Then the two can be connected by a short length of 32A cable with appropriate plugs on each end. And when the power goes down, I can turn the emergency circuit off with the master switch on the secondary consumer unit (because it's bad to use a plug and socket as a switch, interrupting a flowing current and arcing in the process), unplug from the useless incoming circuit, and plug into the genset's output... The genset can only produce about 10A; in practice, that's more than enough to run everything, and it has a 16A outlet on the front, but I'd feel compelled to see if I could find a 10A circuit breaker nonetheless, since with proper sockets stationed about the house, it might be easy to accidentally overload it. But I'm designing the system around a standard 15A socket circuit and a 5A lighting circuit, so that in future, I can get a bigger genset and power more stuff without needing to rewire it all.

What I wonder, though, is if this arrangement would actually be legal under the stringent UK wiring laws. As far as I know there's nothing wrong with having a 32A socket coming from a 30A fuse (after all, a standard 15A circuit feeds many 13A outlets); the question is, is it OK to have a lighting circuit and a set of outlets coming from a consumer unit fed from a 32A inlet socket?

I hope so, since it'd really make switching over to backup power easier than it currently is. And since anything I connect between those two sockets isn't a fixed part of the house wiring it would, I presume, not be governed by regulations, so fiddling with alternate power sources (such as turbines and battery arrays) would be a lot easier.
