failure

Failure is the state or condition of not meeting a desirable or intended objective, and may be viewed as the opposite of success. The criteria for failure depends on context, and may be relative to a particular observer or belief system. One person might consider a failure what another person considers a success, particularly in cases of direct competition or a zero-sum game. Similarly, the degree of success or failure in a situation may be differently viewed by distinct observers or participants, such that a situation that one considers to be a failure, another might consider to be a success, a qualified success or a neutral situation.
It may also be difficult or impossible to ascertain whether a situation meets criteria for failure or success due to ambiguous or ill-defined definition of those criteria. Finding useful and effective criteria, or heuristics, to judge the success or failure of a situation may itself be a significant task.

    Double check valve failure

    Can anyone tell me what the nut is for on the side of the double check valve in the pipe leading to my outside tap? The valve is jammed closed and I wondered if it is possible to free it?

    What can happen when the wrong pump is installed

    I've just found a load of old photos I took when I was an apprentice. Among them was this standard circulating pump that was installed on an unvented secondary return circuit.

    Yet another cheap failure

The flexi in the picture burst just under the tap for no apparent reason other than in my opinion it was cheap tat.
