    Plastic welding?

    Need to pick the brains of you clever fellows, can you plastic weld a hole in a water tank?
    Today the wife was dropping the suction hose in while we where dipping, I was yelling hurry up..........she pulled the pump against the tank, which unfortunately isn't mine.....
    Any help appreciated.

    Yes, it will be polyethylene which welds up well. Much the same as a plastic kayak.

    Any panelbeater will have the gear to plastic weld that (with those little heated staple things for reinforcement). It's just a 240v heat gun and a plastic filler rod.

    Or perhaps a patch from the inside?

    I would buy a tank outlet fitting the type with rubber compression washers. Drill hole bigger with hole saw if reqd to suit bit of silicone on the washers then just cap it off on the threaded outside tank end.

    Like this pic but I prefer the black ones if you can get one.. They come in plenty of sizes good permanent repair ..

    Happy is onto it. You can get ones without the barb and just a BSPF you can plug. Hansen or Anka will make one. Think its called a bulkhead fitting? Harris in Hastings have plenty and Im sure DDS or RD1 or whatever hick supplies you have in Waipuk will sort it out.
