It does have a slight tinge to it, and of course the walls of the borehole are rather brown with (??) muddy deposits, so I'd like to filter it - I'm sure it would be fine for watering gardens and live stock, but . . .my heat exchanger . . . not sure ! |
| hermetic:
If it is high iron content, that would eplain the brown tinge , maybe build some magnets into the filtration. Back to the DHW auxillary heat exchenger on the combi boilers, the one on my now defunct ravenheat was stainless, and used to clog with the magnetite from the CH system, it used to get an anual clean out with acid of some sort., maybe include a magna clean or similar in the water line, or a couple of round ferrite magnets in a filter housing.

I keep meaning to lower a rare earth magnet on a thin string and see what it attracts - goodness only knows whats down there :bugeye: Looks like I'm going to need 32 mm MDPE pipe to get the flow rate, which is a pain as I have quite a bit of 25 mm and also it's going to be mighty fun manoeuvring it down the hole with a heavy pump (18 kg) on the end as well as mains cable and safety rope. Might need to rig a gantry of some sort :scratch: |

Out of interest, how long did it take for the water level to recover from the 5 metres you pumped out of it? |
| awemawson:
It's still not back there Ade - when I last looked a couple of hours ago it was back to about the lower edge of the smaller concrete sections - actually it's quite hard to judge exactly where the level is. Last time it was up to six inches from ground level after a couple of days which make me think that there must be a bit of artesian well acclivity going on as the ground slopes away quite a bit from the top of the bore / well / whatever it is across the site and down to the stream. |
