    I did my basins 32mm waste pipe earlier, 3 solvent weld joints. The pot said wait 15 mins before handling, nothing about testing.

    I just ran some water down it with a hose, about 1.5 hrs/2 hrs after doing the pipes.

    Is this enough? The internet says lots of different stuff, some saying 24 hours! I was only running low pressure for about 10 mins before I worried!

    These pipes are going to be under the floor so I'm a bit paranoid!

    They seemed totally dry and set 10 mins after doing them

    It'll be absolutely fine. Be lucky if I give it 5 mins before testing.

    Phew, I hope you're right! It was only cold water I ran, and it's a waste pipe so no pressure.

    It’s virtually good to go from the minute you connect up. Solvent seals on contact that’s why it’s convenient and quick.

    Ok good to know. I imagine with a basin waste pipe with no pressure, even with no glue it might not leak...the fitting feel pretty tight!
     
  7. Surprisingly it will pizz out...As said the glue sets v v quickly..Try moving the damn things about 30secs after gluing!!

    I use Swan glue for tricky sets or difficult positions as it takes longer to set.

    I have used it on pressurised pipes 10 minutes after assembly however unlike some I do use the cleaner first.

    If I'm doing the odd fitting I may not. More than one or two I'll use a cleaner.

    Yeah I used the cleaner before. I also saw a popular video on YouTube as I'd never done it before, saying be liberal with the glue, but then it squeezes out internally and makes a lip all the way around! I imagine this could contribute to blockages, probably not in the bathroom sink though as people only wash there hands

    A tiny 2-3mm lip inside a 32mm pipe ain`t gonna do much is it.

    You put the glue inside the fitting didn't you. Only put glue on the pipe then excess doesn't end up inside.

    The Floplast glue I got said put it on both surfaces, and the video I watched online. But still I think I was a bit liberal and so got this lip. Next time I'll use a little less, but I can understand why putting it on both surfaces makes sense

    That`s a weak joint bud, best applied to both internal and external on pressurised but internal only will do on gravity pipes.
