Pex bends at a radius of about 8x it's OD. 1/2" pex has an OD of 5/8", so 5/8 x 8 = 5" Radius. 3/4" is about 7" and 1" pex is about 9". Radius, not diameter.

I've used these with good results when you really need a tight bend:


IMO, using 90's wastes a big benefit of pex: it's ability to bend. Obviously sometimes you need to use them, but if they can be avoided, you get better flow and save an elbow, 2 crimp rings and time.


Wondering - why are you guy's suggesting 1" for the main trunk? Pics look like 3/4" main. Not being a dick, just wondering.

1 inch will give you more volume..think of a garden hose..hooks up to a outlet on 1/2 inch pipe...large diameter garden hose will give more water than skinny size of the same length..also down the line if op upgrades water main to 1 inch, house piping will be there already..bigger is always better,,just ask your girl..

Like I said, I bought a Zurn crimpin' tool, 'n love it,...

From the meter, ya don't need 2 unions, so ditch the one not at the meter,...
From there pex to a T for the faucet, 'n a 90 at the wall, 'n another at the ceilin',...

When ya get to where ya wanta meet the copper, just use a pex to copper sweat fittin',....
or a threaded adapter to replace the iron union,...
code dictates a union on either side of the water meters...

I was planning on eliminating the faucet. Not a good idea?

It is 3/4". I've already purchased 3/4", 90s, and a few sweat connectors for the copper. I found the plastic 'benders', but not for 3/4". Just for 1/2". I'll go somewhere else to locate one.

I don't mind using the 90s, but if I don't need to I won't.

He is talking about the Sharkbite on the right if you look at the picture again.

You'll be glad it's there to drain the line before you start. It's not necessary if you never use it, but it could come in handy for all sorts of reasons.

You will no longer need it when you use the Manifold for Hot & Cold. Most times it is placed near the Water Heater if there is a wall or a way to attach Plywood to the foundation and place the manifolds there. I would place it up above the main.

Just remember that if your area is in the process of replacing the old meters with remote read, now is the time to have them do it, so that way you can get the old piping from the Curb to the Yoke connected. Also you can get the Manifolds installed and then go line by line as you work on them. I would put in a section of Copper with Shark Bites from the new connection for the Meter, until you can get the Hot & Cold lines ran to where you need and then connect and move the line over to the Manifold from the old line from the meter. Just remember that the water pipe can be 2' on either side of the markings that the "Before you dig" company marks.

The planning will be a nice project for you to work on, along with getting the materials by Spring, if you are dealing with Snow & frozen ground right now.

That's coming out too.

You'll notice that the outlet is at ground level as well. It's also ungrounded. It's not like basements ever flood, right?

There's lots of fun stuff in this house. 120 years of homeowners F'ing with it (including me). Every time I open a wall, I shudder. When I pulled down the drop ceiling, I had live wires popping out like cobras. Someone just clipped the wires and stuffed them up under the ceiling. They didn't even add wire caps. It was a metal support frame too, and me standing on an AL ladder.

You can't see it, but there's about 400ft of ancient electrical wires laying on the ground. Some of them were around when dinosaurs roamed the earth.

One of my favorite times was when I pull out the bathroom drop ceiling and was treated to a cascade of half eaten black walnuts. Apparently a squirrel lived in the basement at one time.

I'm slowly exorcising the house, but it's fighting me all the way.

Every now and then you come across surprises like that. The Basement is the very first place that I look up at the joist areas for surprises. It is not until it gets cooler, when I first looked into our attic for any problems.

Yours is easy. Take that mess and get a 6"x6" junction box to take that romex and make a proper junction inside, along with the transformer for whatever in a better location.

Already done. Ancient BX is gone, replaced with a new grounded Romex run. New junction box with all cables 'inside' the box.

That setup was powering half my basement. I had to tear out the ceiling to find it.

I can't believe what this contractor did. A firing squad is too good. It took me about a half hour to fix it, so how do you justify work like that? It probably took him that long to jury-rig it the first time.

Looks like they took the old clothe tape from the boxes that had the old BX in them, and reused them. You can get the Ideal connectors that allow you to splice those wires and place them in the wall, without needing a junction box.

We have a slight thaw coming this weekend, so I plan to tackle this plumbing project.

One thing that just occurred to me is how to handle the main electrical panel ground wire.

The current setup is in the pictures added to this post. The ground wire exits the panel, attaches to the existing galvanized pipe with nylon ties, snakes down the pipe, jumps the water meter (I believe the water meter has plastic parts), and attaches to the main pipe entering the house. If I replace the galvanized pipe from the meter onward, is it OK to just tie the ground to the Pex and leave everything else as is?

I assume that as long as the ground is attached to the main pipe into the house I should be OK - correct?
