Hello,

I am doing a DIY project replacing a 48x34 shower. I replaced the whole drain trap and all. Made the distance exactly what the manufacturer said at 24" x 16.5". Well finally got the pan in which was not as easy and my drain is off about 1/4". I am able to move the pipe over to get to the drain but am having trouble getting it in. I have a no caulk drain and the rubber piece that is to go on the outside of my pipe keeps sliding up.

Two questions:

1. Should I be moving the pipe over 1/4 of an inch?
2. Any pointers on getting that rubber piece over my pipe? I have been putting dish soap on the rubber piece to help it go over the pipe.

1/4" should not make the difference here...

Sounds like you are using tooooooo much soap.

Pull up the donut, clean pipe and rubber of soap and then re-install. I am sure there is some soap that will be left and help to slide this on.

Sometimes I use a nut driver or similar blunt driver to push down on rubber, until set to right depth.

Let me know what happens!!

Thanks Mark, I will try this after work. I did put a lot of soap on since that is what I thought it needed. I will let you know how I make out.

Mark, how far is too far, I am guessing at 1/4 inch but could be 1/2. I know if I do move it there will be constant pressure as it moves back if I do not get the drain on the pipe.

Thanks in advance.

1/2" is too much.

Any chance at getting to the pipe under unit??

And..did you set this shower in a bed of mortar or a similar substrate...let me know..??

Answer both questions...Thanks...Mark

Sounds to me that your drain and trap pipe are not secured and move when you try to slide in the rubber collar. These pipes must be secured and that will be an issue if you have already set the pan, have you??

Well I will have to measure before I go setting this. I have not mortared the shower pan nor do I plan to. As for securing the piping, I have not changed the regular configuration of this piping just replaced the trap. It does give a little both ways but not much. So mark, you think 1/4 would be okay but not 1/2 inch. I am just hoping I do not have to do this trap all over again. Oh and since the shower pan is not mortared down I could get the unit but not while the pan is in place. This shower is on the second floor of my house.

Unless the manufacture has included support for the shower floor you will be letting your self in for a ruptured drain seal on down the line. I dunno if a 1/4" cocked raiser will leak on a no-caulk drain but it's always a good idea to have the raiser line up with the drain. I can state for a fact that a 1/2" cock on the raiser will leak. It would be much better if the drain and the trap raiser were in line. Can the base be moved or furred out to line up with the raiser? Just off the top of my head, Tom

"not mortared the shower pan nor do I plan to" this would be a mistake in most installations. What brand pan are you installing? The fiberglass and plastic pans need to be set into a mortar or modified thinset to stop movement and creeking.
