What a *^%$%Y up day!!

What Pex brand are you going to use? I use Wirsbo Uponor. I use Pex all the time and I love it. The fittings that cracked weren't Pex but the new ones are. I am planning on swapping out the rest of the fittings and pipe in the water heater cavity and install a master shut off on the incoming supply line.

It had to be cool today when I am trying to dry things out. It has been in the 90s all week and today 61 was the high and it has been dropping. It is real damp outside so I can't open the windows.

The brands of some of the parts vary, but most of it is Sharkbite brand.
Everything for the main flows under the house and to the risers is 3/4 inch Sharkbite slip together fittings and everything above floor is crimp ring PEX connections.
Everything is in red for hot and blue for cold (same price anyway) and will have chrome plated brass shut of valves at every appliance, and under every tub,shower and sink.
One end of the house will be separated from the other with 3/4 brass shut off valves for both hot and cold also. (in case I ever need to work on or replace anything, it won't shut off both restrooms and showers)

Those 3/4 to 1/2 Sharkbite T's are expensive little buggers at 10 a peice for 20 of them, but it'll make the under the house stuff go real quick.

The 18 or so 1/2 risers can be assembled while watching TV or whatever, then I'll pull the old grey crap out and stick them down through the same holes.
Once all that is done I can go under the house and assemble all the 3/4 and slip the risers into the Sharkbite T's.

I'm doing the entire house starting from the city line, and will obviously have to pull the water heater and start there since the city line comes in right next to it.

The estimates we got were all in the $2,500-$3,000 range but all the parts were only about $700 and I'd be damned if I was going to pay some dude 1,800-2,000 for one days work when I can do it. (probably 2 days for me)
We got all of it online between Home Depot and www.supplyhouse.com but the bulk of it from the online place because they beat HD on almost everything.
The crimp tool and PEX cutters were a lot less at HD.
Both were free shipping on everything.
