New garage time!

I'm optimistic about this!!!! Hoping it all goes well!!!!

The twist type pex fittings kinda suck. Normally barbed fittings are used with steel clamps. Much easier to do.

Looking good!!!!

It's getting exciting... hoping OP the best here. He has been gracious to share his journey.

You're gaining.

Can't understand not being able to get chairs locally. I only have one Lumber Yard in my County and they stock chairs.

Thanks for the update!!!

When I built my barn I had a hard time finding rebar chairs.

How thick is the underslab insulation and where did you get it?

fatjay · Jun 1, 2020

I pressurized the system for the leak test, in 2 hours i went from 45psi to 42psi, so I snugged up the fittings. Left it and 6 hours later i had dropped to 39psi. Tomorrow I'm going to get a spray bottle with soapy water and spray down the whole manifold. I'm almost certain it's a fitting somewhere. I'm leaving it overnight to see what it's at in the morning.

It is the barbed fittings with the steel clamps, no twist. I just had to get it lined up properly which was a pain.

Foam is 2" thick, got it from the local lumber yard.

That amount of pressure drop could be explained by a temperature drop.

My back wont allow pulling any concrete so I hired my pour for tomorrow. Yes it will cost me a $1 a foot for the flatwork. But I consider it well worth it. Pouring a 30x32 slab for a garage. Made the center 12 foot of form so I can pull it and get the truck into the form due to no access except the one side. Will put the chairs back as the truck backs up. With pex and foam this is not an option for you. Back not been an issue I would pour it myself with a helper.
Truck driver will make or break you. The good ones will work the chute without much direction while watching the flow and grade pins. Local plant will send extra chute if you request it. Always have your trucks scheduled in the same round. When ones empty you need the next one ready to pour.
Good luck with yours.

Possible but this would mean about a 50degF temperature drop.

ovrszd · Jun 2, 2020

It's not temp drop. He's got a leak. Assuming he didn't splice any of his runs, which I hope he didn't, the leak will be at the manifolds.

Edit: when operational you'll only run about 15psi.

I found the formula that pertains to your statement:

UpCodes: Unsupported Browser

So yes a 50°F temperature drop would be required. And that could have happened if Fatjay started his pressure test in sunlight when the pex piping was absorbing infared heat and the test finished in the evening when the piping dropped to ambient temperature.

fatjay · Jun 3, 2020

Pressure test was at 1pm at 42psi, 8pm at 38psi, 8am 37psi, and 8pm today it was 35psi. The temperature has been all over hte place, plus sun/clouds. Yesterday ti was sunny and 80, today overcast and 65F. I may have a leak, but I'm fairly sure it's in the manifold if I do.

I cleaned up my existing garage today because I need to get my bobcat in there to fix. Every time I do this, I think there's no way. But every time I manage to do it.

dragoneggs · Jun 3, 2020

Existing Garage/shop... much improvement but it will be a mess in a couple days again. The good news... you can forget those cramped days soon! Again, good luck with the pour.

EddieWalker · Jun 3, 2020

Are you squirting soapy water over the manifold?

While that is the likely place for the leak to be, I would not assume that's where it's at until I found the leak.

MossRoad · Jun 3, 2020

Could you fill it with contrasting food colored water (like green), pressurize it, and look for the leak?

Where's the chop saw. (Like in Where's Waldo?) LOL Jon

There's good stuff in your garage. Have you settled in on a likely cause of your skid steeer problem?

Miter saw is in the back behind the drill press on the ground. Almost everything that was in the garage is still in the garage. The only thing that came out were a couple empty boxes. I do this every couple weeks as it evolves into an unmanageable mess.
