    I'm remodeling my bathroom and have completely gutted it save the plumbing. I purchased the following drain waste valve,


    and I was curious to know if I should use any teflon tape on the threads? The directions only call for putty around the underside flange of the shoe strainer.

    In addition do I need to trim the pieces once they are at the right length or can they just telescope into the waste tee?

    Thanks for any help and advice!

    Slip joint connections...definitely NO tape or putty.

    Depends on the actual length needed, but only cut them if you really need to. You don't want the slip joint tight up the back of the T giving it no room to drain, but you don't want it short, either.

    Tape on plastic parts is not a good idea as far as I'm concerned, I use a little tephlon paste on the threads of the chrome strainer, but be sure it is OK for PVC and plastic.

    I personally use 100% silicone on drains. It is easier to get the drain down tight and it won't hurt the plastic drain parts like some oil based putty will. The non oil putty will wash out if you get it to thick. I also put a little silicone on the overflow gasket if the back of the tub is a bit rough.
