Much effort had to be put in to keep the water flowing and to keep it clean. The Parish Meeting actually held a special discussion at the spring in 1896, to consider what action was necessary to safeguard it.

The spring was well known to Rev. John Morton, Rector of Great Oxendon, who in 1712 published his 'Natural History of Northamptonshire'. He knew it then as 'the Caldwell Spring'.

He has the following to say about it. 'The Medicinal Water at East Farndon, formerly known by the name Cald-well Spring has the same smell and taste, as have the strongest of our Acidulae: has the same ochrous sediment and oil as they have, and agrees with them as to the properties of refusing soap, the loss of its taste upon standing, etc. In June 1701, I boil'd away half a pint of it in an earthen vessel and at the bottom of the vessel had 3 grains of a whitish powder of a mildly saline taste.' 'The water of this spring, at a due distance from its source, has been lately formed into a Cold Bath, which has been made use of with great success'. (No other reference to this 'cold bath' has so far come to light). [There is a well at East Farndon] 'out of which in Frosty Weather, there issues forth a tepid Steam or Mist'. The water comes from a spring in the field once known as 'Levitt's Close'. The Parish Meeting in March 1893 recorded its thanks to the District Council surveyor for 'relaying the drain from Levitt's spring to the watering [place] at the bottom of the village'.
