A bit of a disaster on the filter front after a night of heavy rain. Flow through the filter just isn't happening and the guttering had backed up to the point of overflowing. With the dimensions of the new filter, compared to the proportions of the butt filter, it seems that the builder's sand I used just isn't cutting it. The outlet pipe/weir was seriously clogged with fine sand silt and the filter was leaking from the inlet hose due to the sheer weight of water. I've now stripped the filter, connected the guttering directly to the storage barrel (which is now full!) and removed all the sand and rinsed the gravel. I'm going to get a bag of sharp sand which should have a larger grit size and better filtering properties. The fine builder's sand just seemed to turn to a slimy mud. I'm wondering now exactly how effective the butt filter was. The larger surface area would have helped, but there is always the chance that any water filtering through the butt was travelling down the walls between the butt and the sand itself, rather than filtering through the sand bed. One lives and learns...
A first coat of floor paint on the floor in the kitchenette.
Another sheet of OSB fitted to the partition between the kitchenette and the office proper. This is now pretty much the finished wall, bar a final coat of paint and the skirting.
The floor will need a couple of coats at least to fully cover and seal the phenolic board floor and to give a reasonably hard-wearing surface finish. I'm going to put down some rubber-backed mats to prevent the floor getting too shabby too quickly.
