concrete slab home

[what?]

Hey All- you've all been quite the help, but I still need more. I am installing this shower in a home on slab, and I am curious about the type of trap needed underneath the showerdrain... Does a standard sink-type trap work, or do I have to get one of those d#mn drum traps? I have heard much gnashing of teeth over the use of drum traps...

of course- I will be busting through the concrete to install this, and digging a small pit to install this equpment into, before backfilling with sand, etc.


thanks again
joe

Hi Joe.

I'm assuming you will be installing a PVC or CPE liner shower. That being the case you need a 3-part clamping drain like the one pictured below. Additionally I highly recommend you head on over to our Liberry and read through the entire Shower Construction Thread. http://johnbridge.com/vbulletin/showthread.php?t=5434

I think you will find it very informative

Hi Joe,

You need a 2-inch p-trap under the drain.

[Mike2]

How about that. The trap bidness is all he wanted to know about in the first place. Joe, that's why JB the boss......he reads the questions

Mike2- and here I thought I was going a little nutz...

Thanks both. I was at the Despot yesterday,the nicest name for the place, and when I saw that drain, figured it was what I needed.

Now, if I am connecting the p-drain to an oldschool cast iron drain, is there a special connection I need to buy?

I say that as I don't want to rip out the entire floor and re-concrete the entire thing. Too damn lazy. And I like my back just the way it is. Working

Thanks again all

[Mike2]

Yeah there sure is Joe. But wait for a minute while I re-read the question five more times.

There are special code approved rubber/neoprene fittings for that job. You'll see them in the plumbing aisle. They have stainless steel screw straps around them. The kind I like have a stainless steel band as well. Mission & Fernco are some of the popular brands, there are others. Beware, some are made for plastic to plastic, some iron to iron, some copper to plastic, etc. - different inside diameters. Some are for plastic to iron, that's what you want. I'll see if I can round up a picture.

P.S. Hear ya go. This is one from Mission called Flex Seal.

The drain in my shower was also cast iron so I ended up removing the old p-trap along with about 3 feet of pipe. Replaced the p-trap and pipe with ABS and used a Fernco 2" cast iron to plastic coupling to join the pieces together.

Tested everything and things are working fine.

Thanks,
Rudy

Thanks all- and no slam to you, but I need to learn to trust myself a little bit. Those are the parts I was eyeing at HD. Only, Its good to know the different species- ie cast to copper, plastic to cast, etc etc.


I will begin cutting up some concrete this weekend, to get into the drain work. Thanks again all.

So in the picture from the previous post- If I am using a formed fiberglass liner- not tiling one myself- Does the lip of the fiberglass sit between the lower flange and clamping ring, or between the clamping ring and adjustable drain stem?

I assume I don't need a vapor barrier underneath the pan....correct?

[Mike2]

Tell us some more about this "formed fiberglass liner" you plan to use Joe. Is this a manufactured fiberglass shower pan, pre finished, no tile involved? A fiberglass liner you plan to fabricate yourself? Etc.

[what?]

This pan is preformed/fabbed. I have it sitting in my storage closet at home. Standard type of pan I assume, 36 x 36, 1 inch flange for tiling down to. So this shower will have a tiled walls and a solid floor. Already has the hole for the drain...just not sure how to attach it yet...

[what?]

good morning... just checkin for any updates

[John Bridge]

Well, there are drains specially made for those, as well. The ones I'm familiar with attach to the pipe with either a rubber gasket or with lead.
