You seem to have the right ideas, if you are this concerned about it, why dont you also add some heat trace to the pipes. You can get the self regulating heat trace at most electrical suppliers.

Never heard of that before, The inspectors here insist on solid abs due to the UV and I have seen completely deteriorated cellular abs. Makes me curious if it is due to heat alone, do you have any...

I am also from BC, and in most municipalities that I have worked in, we are required to put a dual check valve on the water entry which moots the whole point of water expansion back into the city. ...

Cellular core abs deteriorates due to uv exposure, the foam deteriorates, however abs wont, use the solid abs for roof vent penetrations...

Edit: for clarity, there are two types of abs pipe you...

I chose the prestige from the list, I have installed a few of them, they were very easy to install, worked flawlessly with a snow melt system, indirect hot water, and infloor radiant heating system....

Put a riser clamp around the pipe and use backing to support the clamp.


I found a picture of what im suggesting, i would put in better backing then that though, it looks pretty flimsy...

Here the only reason to use the brass fittings is for fire rating, the plastic ones have no fire rating, the pipe itself has its fire rating, so without the fire rating fittings you cannot use it in...

Both tools will work fine, I still use my green tool, and used it just last week. As for coming out of the wall, they make two "nice" options for this, they work similar to what davesnothome...

Generally in plumbing brazing isnt very common, but I do it quite often.
I often braze large copper waterlines in residential towers. I use a cutting torch with a special tip, special care must be...

5'/second (3.6GPM) any more then that and its too much wear on the copper pipe, the pex pipe can handle higher rates, up to 8'/second which is what the pex table is based on, thanks for pointing that...

I disagree with alot of what has been said here.

I looked at my pipe flow tables developed from the university down the road from me.

Coldwater flowtable.

Copper should only be at 5'/second...

I agree completely with this, except i would wet vent both the toilet and tub through the lav by using a 3x2 double y, you can bush down the tub side and run 1 1/2 inch pipe.

that works fine but,...

Where I live that would not pass code, this is how we would do it here.
I apologize in advance for my crude drawing :)

I just solved a problem simular to what you are describing, The cause was a tree that grew too large near where the water line ran from the city shut off to the home. The roots squeezed the line and...

How are you certain the elements are still good?
Did you test for an amperage reading?

To test the elements you need to test for amps, an ohm reading is not accurate since you can still recieve...
