I am installing a B&K slip on shower drain with a rubbber sleeve seal.
How high should the 2' trap tail piece br?
Should it be taller than the rubber sleeve?

Thanks,
Dan

Hi Dan...

Set the pipe so it is about 1/8 -1/4" higher than the rubber sleeve once it is all tightened down.

Does the manufacturer of your shower require you to install the shower base in a bedding substrate? Let me know...

PS: Tie a long string around the strainer wrench provided with the drain... lots of these drop into the drain while being used to tighten the inner nut (over the sleeve)
