We had a big leak in the back of the space. Due to the excessive rain. It filled a standard bucket in 90seconds. Frantic running around and balling out…
@JackieO managed to remove, unblock the funnel (filled with pebbles, etc) and reinstall.
Alas their is a big bucket of 1/2 filled rain water. This will take ~4 people to remove http://imgur.com/a/1FxDc
@bmsleight and @JackieO Can you please isolate the power to the back by tripping the RCA by the front wall, it’s near the laser cutter, there is a yellow button with ‘T’ on it.
The leak is no more. The drain is now fixed. The rain is stopped.
Weighing up the dis-benefit of people working in the dark or risk of any leak. Whilst the space has people I would prefer to keep the RCD on. The RSD is working and whilst in use will give us an indication of a problem, Turning it off, we will not have any further indication of any problem. (i.e. Documented risk- assessment)
How many pebbles are we talking about as this may lead to a problem when draining and we may need to come up with a serviceable trap to clear it out. We can not be putting debris down a storm drain that will clog it up.
@Marco_Pagliari If the water bin hasn’t yet been emptied, someone can shift through to take a closer look to see exactly what was blocking it up, not that I imagine that anyone wants to really!
There wasn’t a lot of debris but the tube from the funnel and the hose are both quite narrow, so it didn’t take much.
It was the genius of @bmsleight really who realised that the drain was blocked!
