Disconnection of this fitting is done by firstly, unlocking by turning the screw cap in an anticlockwise direction. There should be a gap and some resistance. Sometimes clips can be fitted, if so, these need to be removed. Use downward pressure on the collet which ids on the end of the fitting. Normally it can be done by hand, but you can also buy a ‘collet release’ tool that will do the job if required. Pull and the fitting and pipe should come apart. The action will leave a plastic seal insert behind in the fitting, this means you will need to take the fitting apart. Archway Plumbers carry out all plumbing work. Taking the fitting apart to remove the seal, you will need to unscrew the screw cap anticlockwise until you feel resistance and then just keep turning, you will probably have to hold the fitting still with a suitable type of pliers. When the cap is off you can remove the pipe insert. As you do this there is possibility that you will also remove a black ‘O’ ring seal and a blue plastic ring. They just need to be re-fitted in the same place that they came from, i.e. the black ’O’ ring first and the blue ring on the top. An Archway Plumber knows how to use speed fittings. Put the screw cap back on and tighten it clockwise. You will feel some resistance so just give it another turn past it and the screw cap should be on.NOTE:This style of fitting is great because it will even work well with copper pipes, the only thing is that you won’t get any marks that tell you if the fitting is secured. There is no need for the pipe inserts when you use copper tubing as it does not require any support.
