Spindle Leak

If you do not feel confident enough to attempt this particular job, you should call on the services of a professional tradesman like a Hackney Plumber who is qualified to carry out the work and will provide a guarantee.

Usually after a stopcock is used for the first time in an extended period of time, you will probably find that there will be an amount of water that is leaking past the packing gland nut. Firstly you must try and tighten up the gland (clockwise) as this might, if you were lucky solve the problem, however all this really achieves is to put lots of pressure on the packing that forces the packing outwards, of course sealing it, but now it will stiffen the valve and make it really hard to function. This will probably not work and re-packing is required. Hackney Plumbers can re-pack glands for all valve types.

Below there is a basic guide to help you to repack a gland:

Guide For Repacking a Gland:
Always ensure that the stopcock you are going to work on is isolated. Completely undo the packing gland nut anticlockwise until it comes away from the housing and will slide up along the spindle. Little water should be visible as the water is isolated. Should any water be seen will be the result of it draining down from the system. Having removed the gland nut, wrap a couple of turns of the PTFE tape around the spindle and press it into the void where the packing gland nut screws, tapping it down with a small screwdriver.

Replace the packing gland nut, just tightening it enough to squeeze the new packing material inside the gland. Open the valve and tighten up the packing gland nut so the water stops passing the spindle.
