Does anyone know who sells sensors which tell you when the water is low in a well? Our current one has blown and the electrician has been unable to source a new one. We are very concerned that the pump might get damaged if someone takes too much water. The current sensor is A "Tense SSR-02". I believe it is a Turkish one



Thanks,

I didn't even know you could get such a sensor. I have a piece of thick string with a piece of wood on the end and knots tied in the string to mark the high and low points. Hardly modern technology - but it never goes wrong!

Would that be an 'Irish' piece of wood John? one that sinks?

Methinks any make of electric float switch can be connected - just make sure that the float is adjusted so that it lies horizontal (power off) when the pump is just submerged.



Any competent plumber should be able to rectify your problem like this at small cost.

Thanks for the responses however our well is 200 metres away and now in dense undergro



flossiewth. We did have a knotted rope but it got stuck and we could not free it. in any case we would need a machete now to reach it.

My above recommendation re. replacing the float switch is dependant on the job being carried out efficiently. You need a thoroughly reliable underwater power cable connector. As these appear to be unavailable in TRNC [although readily available in UK], I decided to make my own - here's how:



One 1 foot length of 1/2" PVC water pipe - slip this on one side of the cable to be connected.



Join the cable by soldering and apply 'shrink-sleeve' - remember to slip on the 'shrink-sleeve' tubing first!



Apply heat from your 'Zippo', or soldering iron to shrink the 'shrink-sleeve' tubing to its max. shrinkage.



Bind the joint with [black] waterproof tape [plumbers normally carry this], then slide the 1/2" PVC water pipe over the connection and squirt [preferably 'aquarium'] silicone into the pipe until it is oozing out - best to squirt from both ends.



Leave your connector for, preferably, a week and then 'Bob's your uncle - Fanny's your aunt - jobbie done like a 'bought one'!
