    Let's say I have to replace a spray body,I twist it out with the Channelocks,see that it was installed with a nipple.I coat the female threads of the new body with some Rectorseal(just the right amount),then spin it back down.No muss,no fuss.

    In an open hole,I use tape.It's the "Use No Dope" thing that bothers me.

    Should I watch my back?

    I remember the first time I installed a sprinkler head and read " use no pipe dope" I thought " how did they know it was going to be me installing it"?

    My understanding is that the "use no dope" disclaimer is to limit the knuckleheads that put a 3" bead on the riser and then end up with clogged filters. It shouldn't hurt the plastic or anything.

    You do not need rectorseal. Period.

    If you use a Marlex ell, that is true. Period.

    You don't need the paste dope period, unless you have a bad case of limp wrists. Old paste dopes were never intended to contact plastic, which wasn't in plumbing use when the paste dopes were formulated.

    Only ROTAR has the wrist problem, the newer dope is made for plastics.

    Major diss :waving: ~ When those stickers first appeared, a lot of paste dopes were original formulas, and death to some plastics.

    I always read it as "Use No Pipe, Dope".

    Then I wondered how to get water to the sprinklers.
