I am slowly bringing my place “online”. I have fixed the pump and all the piping not related to hot water. Everything flows. I will need to get the water testing but for now it seems that the water seems to run clear and well seems to fill (let it be very slowly).
So my well was most probably hand dug many many years ago. It has been fixed up some but still has rock walls. It is around 5m deep(16.5 ft) and at least a meter (3ft) wide. It was just sitting for at least 15 years, so I need to clean it and assuming to remove sand in from the bottom. I could run the water empty and get in and scrub and bucket out the sediment but I think that may be dangerous. For example, with its age I’m not sure if the lack of water would make it collapse. I have also heard about shock cleaning the well with bleach but again not sure about that( some of the hot water pipes are copper if that matters). I’m in Japan if that changes anything.
I don’t know how to clean it so any information would be very appreciated. #home source
