I am replacing a shower that was installed on a cement slab.
I will probably be using noble company products for the liner etc..
However I need some guidance on the install of drain system.
Attached are some pictures of the existing situation... can anyone help suggest something. On some other groups I'm reading about swallow p traps, but there is a terminte issue to deal with... can anyone help ?

I'm having a real problem. In none of the five pictures do I see a shower stub up or even a trap. And I haven't the foggiest idea what a "swallow trap" is. When I googled it gave me directions on how to build a swallow trap for birds. And what do termites have to do with installing a shower? Please point me in the right direction. Regards, Tom

Hi thanks for responding.

The description of the plumbing is as follows. In shower pix 1, the tube on the far left is a run from the upstairs tub trap. The trap taps into this down tub, the tube also continues up to a union in the attic and is then vented to the roof. That tubs runs into floor and merges at a junction as shown in Shower pix 4.
The tube next to this tube (next tube to the right) is being removed totally, as this used to be a drain connection for a washer that used to be on the other side of the wall.
The 3rd vertical tup is another vent tube that goes directly to the roof, and into the floor it is joined at the connetcion as shown in shower pix 4.

I plan to use Noble Company's http://www.noblecompany.com/ sheet membranes and shower stall kits.

My question is, what type of trap should be used in this situation?

In shower pix 5 in the top right of the pix there is a old rag stuffed in the old trap. As you can also see towards the bottom right of this pix is where the trap, a vent tube, and the upstairs bath drain run into.

The area is 36 deep by 48 wide. Im planning on removing all the plumbing you see, with the exception of where all the tubes run into the bottom right of shower pix 5. See shower pix 4 for a closeup). The new drain will be centered arcoss the dimensions mentioned above.

I was told by a plumber that when burying drain plumbing in the ground the home becomes more vunerable to termites. I live in a prone area (Long Island, NY).

As for a shallow ( sorry type swallow is worng) I meant to say shallow P trap.
I would like to run all the new PVC plumbing into the junction as shown in pix 4. Is this possible? What precautions should I take when burying PVC? etc...

Thnak you so much... Bobby

Forgot this, a plumber also told me I need to leave both the upstairs trap and the trap in the cement accessible?? I have no idea how that could be remotely possible.

Hey speedball1? Could you assist here ?

What's the problem with using the existing trap?

"My question is, what type of trap should be used in this situation?"
A regular PVC "P" trap should be used. I can see no reason for a "shallow trap" in fact I don't even know what one is or why you would need it.
Cut out the cast iron that won't be used any more and leave a open end on the cast iron that you can convert to PVC using a No-Hub Coupling ,(see image). Once converted to PVC you can pipe the trap to where you want it.

Are you planing on installing a manufactured shower base or a custom tile one? Your remark about using noble company products for the liner leads me to think you're planing a custom tile shower.

"I was told by a plumber that when burying drain plumbing in the ground the home becomes more vunerable to termites. I live in a prone area (Long Island, NY)."
And just where does your plumber suggest you put the drainage if not under the cement?

" What precautions should I take when burying PVC?"
None.

" a plumber also told me I need to leave both the upstairs trap and the trap in the cement accessable??? I have no idea how that could be remotely possible."
Your plumber meant for you to leave a access panel behind the upstairs tub trap. He was wrong about the basement shower trap. You install the trap and raiser and then cement over the trap and leave the raiser about 3" over the pour.

Good luck and please excuse the delay. I have company down from up North.

Thank you very much... I will post some pix of the roughed in drains...
