I think the best approach to brush painting this stuff is not to :clap:

Spray for me from now on.

. . . I got that socket mounted :thumbup:

too large hammers eh? never had that problem before, and I must admit
I almost always spray , but as you say, cleanup and gunwashing is a pain if you only have a bit to do!

So having fitted that 1" BSP bung in the tank I had to turn my attention to what to do to support the 'house water' inlet and the overflow pipe. Although the plastic tank is quite rigid I don't want pipes hanging off it unsupported. I came to the conclusion that yet another 6 mm plate was called for, suitably pierced, for fittings to run through and clamp to.

Bit of a mare measuring up precisely where the holes need to go - I ended up with three iterations of plastic templates before I was satisfied. Straight to spraying this time, no messing about with brushes :clap:

Having done that I turned my attention to a bit of wiring. I wanted to get the thermometers at least, wired up. I've run three phase to the overload trip, and a single phase feed to the low current breaker feeding the 12 volt power supply for the thermometers. I've temporarily connected a single phase input for testing, so the thermometers are now powered up, but their sensors are still just dangling in the electrical enclosure. The 12 volt 'Power On' indicator proved to be a useful commoning point for the four displays.

While I was doing this, Andy arrived and started concreting in the surround to the manhole cover, and the slot through the path where we ran trunking under the re-bar. He has cast the 'roof' for the pump house off site, but it's still too green to move - scheduled for Friday evening.

Hope to get the pump electrics connected tomorrow.

Just a thought Andrew, have you been able to test the generator under the expected load conditions?
You are plowing on with the other parts of the project but it would be a shame if after all this work and dedication that the project failed due to a defective power source.

I'm sure that with your normal thoroughness you have covered this but I just wondered.

He'll just have to rebuild that too...

I've only been able to load the generator up to 16 KVA and it didn't even notice that it was loaded !

Yes that IS one of the imponderables, also I don't know that the big blue furnace driver will work at high power either as it's only done low power 'pings' recently.

These things are like skittles, you need to keep knocking them down one by one as they crop up :clap:
