will have another go in morning with wd40.thanks
The best way to get the two sections apart is to use two people and rubber gloves. Get one strong person to hold the top section firmly (without crushing), make sure they hold the section above the joint overlap. The second person needs to then hold the lower section as close to the joint as possible and twist the section in a clockwise direction (this will look like you are turning it the wrong way!). Do not try to pull the section apart at all, as soon as a little twisting happens then you can start to exert some pulling force, but still mainly twisting. If this is to no avail then some heat may help. A heat gun lightly applied will help with this process.Once they have separated we use Petroleum Jelly (Vaseline!) which seems to reduce the friction after extended work periods. However, it needs to be used sparingly. After applying PTFE spray, wipe a very thin layer over the male joints. It seems to give more friction to the joint on light contact which is good as it grips without needing to be tight, but then even under pressure it allows the joint to separate with greater ease. I'm finding that it only needs re-applying every couple of months.
I have to use mine in anger for the first time next sunday 12/07/09. What can i do to make life easy, i've never had it out of the holder.
to stop this becoming a problem you need to clean the muck out of the joinning sections. hope this helps
