    I had to move a shower drain and used a 2", 4-Band No-Hub Coupling to tie the P-Trap assembly onto the old drain line. Is this acceptable and, if so, should I tighten the 3/8" clamp screws to a certain torque or is hand-tight adequate? I plan to cover everything visible in the pic with sand to about two inches over the coupling, fill the hole with concrete to floor level (formerly a sunken shower pan) and have a new tile shower installed with traditional mortar bed.

    I use a torque wrench. Hand tight can mean many things since we all have different strength levels.

    Less torque than you use to remove a stuck pickle jar and more than a twist off beer cap. That is the perfect level.

    Or you can buy one of these...

    I played a double header Monday night, drinking an energy drink before the game. I'm still wound up.
    I went 3 for 4, but got out on the last at bat of the second game to end the night with men on.
    Lot's of things going on though. Lot's.

    That's 60-INCH pounds, so, yes, 5-Ftpd is the spec for fittings 1.5-10" in diameter (80-in/pd for larger pipe).

    If his band has 3/8" nuts, the standard No-Hub wrench will not work because it is 5/16".
