If there's no sound then there's no source of power so check the condition of the leisure battery first with a voltmeter. A fully charged battery should read about 13 volts but if it's it 12.7 or below then it will need re-charging. If it's below 12.5 it may very well be scrap as leisure batteries are difficult to re-start. If the battery proves to be okay then turn the toilet flush dial and then check with the meter for any power there. If there is no power then it could be a defective switch.

a fully charged lead acid battery should read 12.5 to 12.7 volts.. this is off the charger and left stood for a few hours.. the 13.5 volts is whilst the battery is on charge..

if the battery ever goes flat (dead flat showing zero volts) and is left for a period of time (weeks mostly) in this condition it may not take a normal charge..

the more a battery is used and the deeper its cycled the quicker it wears out.. you can run one right down and it will still work but its not a good idea to do it too often.. what really destroys them quickly is letting them go dead flat and leaving them like this for a period of time.. the period of time is variable..

oddly enough batteries that are never used and kept fully charged all the time live a lot longer than batteries that are used.. he he

if there is a basic rule its.. charge them up as often as you (conveniently) can and avoid too deep a cycle if possible..

car starter batteries are built lighter and really do not like deep cycles.. but if the van is left connected to the mains all the time a car starter battery could be used and still live a reasonable time..

to add.. car starter battery.. lightly built (cheap) and not designed to be deep cycled.. it will wear out very quickly if it is deep cycled..

leisure battery.. more heavily built and designed for deeper cycles.. it will still wear out quicker if its deep cycled than if its shallow cycled..

the way a lot of caravans are used.. always plugged into the mains and on charge suggests there is no real need for an expensive deep cycle battery.. having said that some of the so called cheaper leisure batteries now being sold are probably not that clever at deep cycling ether..

trog

ps.. a simple home battery test.. leave it on charge for a day or so.. place it under a known load.. lights or whatever.. a good 110 AH leisure battery should put out ten amps for ten hours before the voltage drops to ten volts or so..

if the battery only manages five hours it means its half knackered.. a good 110 AH battery should power a motor mover for four or five hours of actual moving..

i strongly suspect that most peoples batteries are at least half knackered.. some a lot more than half knackered.. he he

On reading from another site,thetford does not mention a microswitch and would rather you bought a pump which would be a wrong call also,they mention a little plastic ball in the flush Assembly which could be stuck and tapping could free it.
