Today I was walking around some rocks on the beach and I found a self filling and emptying rock pool which was connected to the sea via a hole in the bottom of it. The gentle waves were causing it to fill and empty every few seconds. I reckon something like that could easily be scaled up and taken ...

My preferred cable jointing is twisting the conductors together, then soldering and then fitting two layers of the shrink sleeving that has the hot melt glue. Makes a pretty much 100% reliable joint, and is the way I joined the short cable from our submersible well pump to the long cable that comes ...

Time for some divination of the water. get yer wee flags out! Divining for water here would be hilarious! The stuff is everywhere at this time of year, with goodness knows how many springs flowing like billy oh over the other side of the lane. Much further up the valley, towards the chalk escarpmen...

Should make a significant difference. at our old place I found that just sealing up all the places where there were draughts made a heck of a difference. I rigged up an old electric car radiator fan in a bit of ply and taped it to an open widow, so I could try and feel where the worst air leaks were...

What's the betting we see a rise in the price of insulation? Spoke to the chap that runs our parish council just before Christmas and he was complaining about not being able to find anyone to give him a quote to add insulation to his old house. Apparently the insulation companies are now getting rus...

I spent a week in Spain learning to fly a paramotor years ago. A few of us used to meet up locally and fly around the local area, but my left knee gave out, and I just couldn't run to launch any more, so sold it and gave up. Great fun, though.

We have 300mm of insulation under our concrete slab (which I know is a bit OTT) but we still lose around 10% or more of the heat we put into the slab down through the insulation to the cooler ground beneath. Doesn't this even out a bit over time? In the past I read about only insulating the perimet...

You want the UFH beneath the slab... Surely having the UFH pipes on the lower side rather than in the centre or closer to the upper surface increases the heat losses downwards, doesn't it? We have 300mm of insulation under our concrete slab (which I know is a bit OTT) but we still lose around 10% o...

Few things that are bothering me with some of the assumptions OGB - If the leak had become larger, wouldn’t this have had a significant impact on domestic water pressure in those homes fed by the pipe ? I know when we had our leak, water pressure was the first indicator - at its worst, we had virtu...

I think you mentioned a stop valve at the top of the lane... Is it possible that after the "repairs" it's now only cracked open so the audible leak has disappeared? This would allow them to claim that they have completed the job - until the people on the main start to complain of loss of ...
