    Removing Glued fittings

    Hi

    Does anyone have any bright idea's on how to ream out a glued fitting. I have a couple of check valves I want to re purpose on the new pond but they have been glued up. I can saw off the pipe but I need to ream back out to 1.5 inch to take new pipe.

    Anyone done this?

    Andy

    Use a heat gun, after firstly cutting pipe that's inside fitting length ways into 4 sections, then use a thin screwdriver and gently ease sections out once you see glue melting.

    It is fairly straightforward with a fine nozzle on a hot air gun, hold the fitting in a vice and then heat up the inside of the pipe, you can either ease a flat headed screwdriver in between the pipe and the fitting or if you leave a spare circa 10mm of pipe you can grab this with pliers and twist to break the bond. It is a question of just a bit of heat, manipulate, heat, manipulate etc.

    Andy,

    Failing that use Flexseal EPDM Plumbing Connectors to join the valves to the pipes. I gave up solvent welding expensive bits of kit together ages ago and I have probably saved a fortune.

    Hot gun and in my case I used pliers to get hold of the edge of the pipe being removed - pre-cut carefully along it not to damage the part you want to reuse - benefit of using pliers is, that you can rotate them inside while holding to the edge thus with a bit of heat gun help you can easily remove the pipe - just use heat gun sparingly and at not too high temp setting - try it out on leftover pipe prior working on the fitting / valve you want reuse - too much heat can deform the fitting / valve....
    You get what you pay for - or better - what you make yourself.

    just rejoin with a straight rubber boot,or cut pipe back and use a reducer over unions to pipe,saves hassle tyring to desolvent it and its easy to remove again if you need to,,,,andi

    The heat gun trick did the business, a little persistance and wiggling and bingo......well the scrap test bit worked now I can move on to the real job what could go wrong

    Heat round and round the inside of the fitting, then do it some more, then push one leg of a snipe nose plier in between the fitting and the bit of pipe to be removed, close the pliers and twist hard, the pipe will just peel away from the fitting, I done it on about 3 dozen fittings and valves and they’re all good, maybe a bit of a clean inside the fitting with a flap wheel on a dremmel if needed.

    There's a video on you tube somewhere
    you cover the bit you want to remove with the solvent and set it alight when it's finished burning use some grips and wind it round the grips
    hope that makes sense ��
    I've done it loads of times now and works a treat!
