    Solvent welding ball valves

    Hi all, I am using 1.5Ē Yamitsu solvent weld ball valves on the waste of my filter. Iíve not solvent welded ball valves before and Iím concerned about the glue getting on the valve surface and causing damage (either sticking it in position or causing a leak).
    Any advice on this please?
    Thanks
    David

    Use silicone will stick just as well and removable if you decide to change anything

    Nice idea, thanks.
    So I push the valve in place (no silicone) and then run a bead around the join...?

    I would put silicone all around the end of the valve and as you fit it rotate the valve as you push it home so you get good coverage

    Ah ok, so I follow the same process but replace the solvent cement with silicone because silicone doesn’t damage the ball valve surface.
    Thanks, all clear now!

    Or use rubber connectors which makes it so much easier to replace the valve when the handle snaps. And it will. It might not be this winter but if it's outside it will eventually snap.

    Would this stuff help to keep them moving more easily? Assuming it’s on the waste and you can get to one side of the valve of course.

    I was just going to suggest the same sort of thing with the flexi rubber boots as that's what I have done.

    Depending what fittings and pipe you have you could use couplers or if you have pressure pipe fittings you may be better off using reducers as I found using 1.5" pressure pipe and fittings a 1.5" reducer fits the pipe and 2" reducer fits the fittings so I was using 2" to 1.5" reducers and not gluing anything.

    I wouldn't use WD40 on anything that may be likely to come into contact with your pond water but instead would look for a fish safe lubricant.

    Good luck
