    Hi mate. I have only ever used the one type
    This one.
    It says it can be used in spas and pools.
    So I suppose it's safe with humans.
    My fish are never affected by it.
    I have used it now over 25 years.
    If you don t seal the lid cap properly it will go off pretty rapid. And when I have finished with it I always rag the threads down dry. As it is a nightmare to get the cap off next time you use it.

    I would be more bothered about the fluidity of the solvent than a date.
    They do start to set in the tub, when it's going thicker it becomes impossible to work with quick enough.
    Especially is that the case with with bigger pipes.

    Hello fred me old mukka hope alls well. Nice bit of advice mate. Thereís so many different brands and sell it all in diy shops that Iím unsure if all brands are ok. I did buy one from my local koi dealer but the use by date was approaching to years old and me and me dad couldnít unscrew the lid. Took it back and the rest was the same so just got a refund. They do sell this in bnq so may just get this then. IMG_9489.JPG

    the flo plast and most other solvent cements you get from DIY shops are designed for waste and soil pipes like the kockney koi style pond fittings.

    if your using pressure pipe you'd be better off using pressure adhesive like the weld-on and tangit range, but these are also fine for waste and soil pipes too they are just a much stronger solvent cement.
    You don't have to be a pipefitter to keep koi...
    but it helps...

    i'd agree with that,
    as the pressure in a pond setting is very low compared to what it's designed for at 10-16 bar.
    and it will easiliy cope.

    the only difference i notice between waste pipe cement and pressure solvent cement is,
    the pressure cement is a little more forgiving in the open time especially when using 4".
    it generally allows you to slide it all the way on and position it, before it 'grabs' the fitting and you can't move it.
    You don't have to be a pipefitter to keep koi...

    I also use flo plast on everything. No issues. Seems to stay useable in the pot for a lot longer than others I've used. Some of them once open only last a month before going off. Interesting about the pressure adhesives having a longer working time. Will probably get some of that when I do the bottom drain.
