How do these basic cisterns work? We have one at work that just appears to consist of a supply pipe entering a cistern. I've always wondered how is it triggered to flush? And how often does it do so? There are no external sensors or anything. Does it just constantly fill to a trip point, then empty and fill again? This seems a tad wasteful. Are they?

It will flush as long as there is a water supply to it. If it is of the basic simple type, it is likely that there is a drip tap called a 'pet-cock' above the cistern which drips until a level is reached where the water self syphons to flush.
It one pipe inside a cone, and when the water reaches the top of the pipe, it overspills internally and syphons the water out.
You should be able to slow or speed the flush by altering the drip rate on the p-c.

They can be wasteful, flushing 24/7 when buildings are not occupied. There are various water saving devices available to trigger filling of the cistern or flushing when the premises are occupied.
I did my apprenticeship through the YTS, fitted a Cistermiser valve at the YTS folks premises towards the end of my training. The deputy manager who was also a local councillor then had them fitted in all the council buildings as he realised how much water was being wasted and how much the council could save.....

haha not heard of YTS for donkeys years, i did a 6 month YOP pre apprentiship in 1978, which i'm sure was before YTS, and got £16.40 per week
Was 1989, I was on about £28 a week. It did rise to £35 in the 2nd year.... Took a part time job in Tesco evenings and weekends to earn a bit more. My supervisor (at Tesco) was often complaining about me going into work in the evening still smelling of boss white/flux/covered in tile adhesive/whatever else we'd used during the day.... Just didnt have time between finishing one job and starting shift at Tesco!
I`d been out of my apprenticeship for 3 years by `78
was waiting to become a yuppy in the 80`s DIYnot Local
