Trimming and Tatting

Today I took down a pack of rounded architrave and used the compound mitre saw to chop some angles and bevels. The door to the loo is now trimmed in and the 'skirting' is now in place. A second coat of paint on the loo wall and the first coat on the main loo floor is now done and drying, and I got a second coat of floor paint on the section of floor outside the loo.

The partition wall between the kitchenette and office now has it's edging trim and is looking much more finished now, Just another coat of Sandtex and it's done.

Architrave and trimming finished around the door-frame and the end wall and all the woodwork now ready for a final rub down with a fine emery paper and then a coat of gloss paint.

Apart from the final decoration and trimming out, the loo and water supply is now finished. The new slow sand filter is in place and water is running nicely. 

The guttering feeds in using a couple of sections of solvent-weld 21.5mm waste pipe and this has been terminated with a tank connector. The 3/4" plastic thread usually passes through a tank body and is secured with a backnut and a couple of rubber washers to produce a watertight seal, but you can see in the image above I have used a 3/4" appliance hose (washing machine cold fill hose) to make the inlet and outlet hoses for the filter. The outlet hose acts as the weir to the storage tank and the outlet height has been set to leave a 5cm layer of supernatent water on the surface of the filter so it always maintains a wet layer above the filter media and prevents the bio-film from drying out. So far, no leaks!

The bucket is left over from my initial purging and run-through...it doesn't need to be there, but as I'd just painted the floor, I couldn't retrieve it!

Close-up of the filter showing the inlet and outlet hoses. There is just enough space to open the threaded cap on the top of the filter to remove and clean the foam biofilter as needed, and the whole unit can be removed for more serious cleaning or maintenance as required. The filter can be drained by removing the outlet hose from the storage tank and draining it down into a bucket, the inlet can be disconnected and the whole filter column removed and worked on. For now, the column is just supported by the stand at the bottom, but ultimately I may fit a 110mm drain collar bracket just for additional support.
