I wrote to the help desk a few weeks ago and got some very good advice about my stack pipe replacement. One piece of advice was to have the risers replaced while the wall was open.

The plumber who is redoing all potable water I the house has installed a new shut-off valve. But he went from the 1” galvanized pipe that enters my house to a 3/4” cpvc. (Plumbing 1)

Then it reduces again to 1/2” cpvc in the risers. Is that all right? In my mind it will cut down the amount of water that will flow through the pipes, right?

I REALLY DON’T KNOW ANYTHING ABOUT THIS but my original reaction to all of the new plumbing going in is that all that STURDY galvanized pipe now looks like its been replaced by “tinker toys”. And all these little twisty bends and 90-degree angles make it look like things are going to pop at any second! (Plumbing 2, 3, and 4)

Is this a common reaction to new replacement pipe?

Oh yes, the picture of the new stack is in “Plumbing 5”

Yikes!!

Are you having this work inspected?

I know enough to get by doing a little of my own work. It really appalls me the amount of people that seem to be practicing plumbing, heating, and electrical that know less than I do. I wonder how many of them are trained or certified in all 3? Any of them?

Huh?

A 3/4" main with 1/2" branches are the standard in my area. There's no doubt in my mind that you will get better pressure and more volume out of the 3/4" PVC then you'll get out of your old 1" galvanized. However, your plumber showed his inexperience with all those elbos and offsets. Let's hope he primed the pipe and fittings before he glued them. If he didn't you're in trouble on down the line. Good luck, Tom
