All this entails water supplies for both horses and greenhouses. While the main feeds are buried and fairly safe and reliable it's inevitable that the last few feet to the horses' waterers and to timers for the greenhouse are exposed and vulnerable to damage. One of our horses is very good at pulling pipes off!
So what devices are available for limiting the water loss if one has leak and detecting that water consumption is a lot more than normal?
We do try and turn down the taps feeding the horses' water so that there is only a trickle into their waterers (which are ball valve controlled) but a tap is not a reliable way of maintaining a small flow. Are there any devices for 'metering' water reasonably accurately so that a catastrophic leak (i.e. horse has pulled pipe off waterer) won't lose huge amounts of water? It would be useful if the 'metering' could be turned quickly to full flow for washing out etc.
Secondly some sort of alarm to draw attention to large flows that occur for a significant length of time would be useful. The meter isn't all that accessible and you can't really ask/expect house and horse sitters to grovel around in the hedge checking the consumption.
