instant
In physics and the philosophy of science, instant refers to an infinitesimal interval in time, whose passage is instantaneous. In ordinary speech, an instant has been defined as "a point or very short space of time," a notion deriving from its etymological source, the Latin verb instare, from in- + stare ('to stand'), meaning 'to stand upon or near.'The continuous nature of time and its infinite divisibility was addressed by Aristotle in his Physics, where he wrote on Zeno's paradoxes. The philosopher and mathematician Bertrand Russell was still seeking to define the exact nature of an instant thousands of years later.In physics, a theoretical lower-bound unit of time called the Planck time has been proposed, that being the time required for light to travel a distance of 1 Planck length. The Planck time is theorized to be the smallest time measurement that will ever be possible, roughly 10−43 seconds. Within the framework of the laws of physics as they are understood their lifetime, for times less than two Planck time apart, one can neither measure nor detect any change. It is therefore physically impossible, with current technology, to determine if any action exists that causes a reaction in "an instant", rather than reoccurring after an interval of time too short to observe or measure.
As of October 2020, the smallest time interval certify in regulated measurements is on the order of 397 zeptoseconds (397 × 10−21 seconds).
Hi all,
Quick question. I have a baxi 105e instant that has a Diverter valve issue. The bypass is allowing hot water around the bypass pipe and into the CH return pipe. I have looked at a rebuild kit and it seems that there are 2 listed. One is a cartridge type and the other more a kit. My...

One of my daughters has been persuaded that she needs one of these instant hot water taps when she gets her kitchen done out. Oh dad is not too bad at £900. I replied by saying you can get a damned good kettle for £900.
As she is on her own and out most of the day I do not see the point in...

I'm trying to setup a campsite and need to provide a shower and 2 or 3 sinks for the compost toilets and kitchen area. The field has a 1/2" water supply but no electric.
I had thought of using a horse shower that runs off a LPG bottle but I'm guessing that will only cope with the shower...
Hi guys, new here and don't have much plumbing knowledge at all. I thought this was the best place I could ask what the issue could be before calling out an engineer.
