Thats a rather gear expensive "justforthehellofit" system promo for a thing very good for small subsoil pipes. Would it not make more economical sense to send down a few glassfiber boat repair guys with lamination epoxy, paint rolls and glassfiber cloth rolls to a tube perfectly big enough to walk in ...?
Just curious bc I used to do this years ago up to 88" lines. Well used water invert it and cook it. How exactly does the uv work? Looks like it's inflated with air which I've done b4 also but cured with steam. But where does the uv come into play?
