    Hi all,

    I need to start gluing the PVC I've just purchased from Astore - now I just need to know which glue is "reef-friendly" and also, where to find it?

    Can I get the same glue they offer at Astore?

    Thanks.

    The glue Astore was selling was costing me R26 and you're telling me I could have used it?

    Dammit!

    Thanks Jacques :thumbup:

    I use Alcolin PVC weld, works really well. When I first put all my plumbing together I used silicon just to make sure all the lengths etc. were correct and then cleaned and used PVC weld. Some of the joints I want to be easily removable I have left with silicon, this won't work very well or for a long time on high pressure joints though.

    PVC cement is my favourite brand, white plastic bottle with some red on the label.

    oh and if you are going to do allot of pvc pipe cutting i would recommend this (this is one for up to 25mm, but you get them up to 50mm),
    it works like a pair of scissors to cut pvc, neatest and fastest way to cut pvc, also get yourself some fine wet sand paper, you use this on the pipe to get it smooth and clean where you will be using the glue[​IMG]

    Thanks dude, I appreciate it - I was planning on just using a saw but that cutter looks a hell of a lot easier.

    The guys at Astore said that I could/should use either acetone or meths to clean the PVC before gluing - is sanding it down preferable?

    Use a very fine wet sand paper (under a flowing tap), it basically just cleans the pipe and makes it super smooth, better than any chemical will. Will have to use some elbow grease though :p

    BostiK PVC weld also works pretty well and it dries clear. Like @jaquesdp08 said, get the HP version, it's definitely stronger. Make sure both surfaces of the join are roughened up first. Run water through the plumbing after joining and before installation as you always seem to get blue PVC dust in the pipes (Ya, seems a no brainer, but I forgot to on my DIY PO4 reactor [rookie error]).
