Hello All,

Im on the third floor of an old triple decker right outside of Boston. I have a pantry now along side my current bathroom. I want to make two full baths, one with shower, one with tub/shower. I want to move the current drain for the current toilet about 10 inches, then put a wall between it and another toilet, which will be new and of course require a new drain... Is this reasonable? Could I use the existing drain and slap a T on it and run it to the two toilets? Building up the floor a little of course? Whats the best way about doing it? Any help, would be greatly appreciated, thanks.

Hi All,

I have copper piping in my current bathroom but would like to change over to plastic pipes/tubes or whatever when I begin to remodel and put in another bathroom adjacent to the current one. Im up in the third floor and the pipes all come up from one spot... Can I tap or cut the line and then attach some plastic piping to both the cold and hot water pipes, split them once each to go to showers/sinks...? I would like to make the change over right when it comes up from below, so I can do the whole two new bathrooms in the plastic piping.... Is this possible? Thanks your your time...

As far as going from copper to plastic (cpvc) goes, all you need is something like this:

...but better than the one in the pic, which has a compression fitting for the copper, get one that you sweat (solder) onto the copper.

I think 3 fixtures off of a main line is the max you want to go, but stay tuned for our Plumbing Expert to confirm on that end of it.

Thanks for the quick reply. I have been absolutely loving all this info, great stuff! So, do I have to make some threads where I cut the pipes? Is there a tool for that? How do you link the plastic to plastic pipes?

RickJ

No threads needed. Both copper and cpvc can be cut with one of these:

cpvc is put together with glue: All you really need is the pipe (usually comes in 10' lengths), fittings (elbows, unions, and adapters for your shutoffs) glue and primer.

You'll find it very easy work.

What about PEX piping? This seems even a little cooler!

RickJ

I've never used PEX. From the brief bit I see on the net, it seems easy enough for a diy'er, but my guess is it's cost is at least 5-10x what cpvc is.

What do you mean by "cooler?"

bougart

Cooler = much easier to work with and bends =)

On Amazon im seeing a 100 ft coil of it, 1/2'', for 35 bucks:

35 cents a foot is sure cheap enough. Check the fittings prices and be sure you have the tools and know how to put it all together.

If price and ease of installation are as easy as cpvc, I'd give it a shot. I do see from some surfing, that it is gaining popularity.

If I were going to install back to back bathrooms I would use a common drain and vent. I would tie the toilets together with a double wye and eighth bend(see image) and the two lavatories with a 2" cross drainage tee to pick up both lavs and a common 2" vent off the top of the tee which will service both bathroom groups. . The two tubs/showers to be tied into the lavatory drains where they will be wet vented. Sound like a plan?? Good luck, tom
