How deep a bore? You can get various electric bore pumps that will fit into a 4" bore.

Hi, Andre.

We have a well with an ejector – the well is about 16 cms diameter – but – our ejector is, as you note, an 'el Cheapo' cast iron product, and they are freely available 'off the shelf' here. It has been in continuous use now for about 6 years. I had to extract the ejector about two years ago due to an issue with a pipe connector, and was surprised to find it was NOT seriously rusted or showing any other signs of damage, apart from small traces of rust around the edges of the casting – certainly not serious.

The ejector itself was painted (by the manufacturer) with some sort of dark green paint, but no idea if it was some special type. I simply wire-brushed the thing clean, and gave it a quick spray with a can of paint I had on the garage shelf.

However, the ejector was fitted with a galvanized tailpipe to prevent pumping the well dry, and this was horrendously rusted! – the galvanizing was a complete waste of time. This tailpipe was replaced with a plastic pipe as a result.

This well supplies all our water, including drinking water, so we have it checked and analyzed at regular intervals for any nasties, and have never had any reason for worries. The thing that does make me wonder is that despite the corroded tailpipe, nothing showed up the analysis, nor was the water discoloured – maybe we should get the analysis done elsewhere!. That said, we have drunk the water for a long time now, and have not had any illnesses which could be attributed to the water.
