    Trench drain installation question

    Finally! I am in the finishing stages of my garage, I bought a trench drain to put across the door, the instructions say to pour concrete around it 4" below and at least 6" all around. I feel like there is no way that a 12'-4"x6" block butted up against my floor is going to stay put after the...

    Insulating around Selkirk Insulation shield

    I'm just putting the finishing touches on my garage and I realized I'm getting a massive draft out of the gaps around the insulation shield of the Selkirk chimney. I didn't tape the vapor barrier to it and it just has roxul insulation pushed around it. The easiest thing to do would be spray...

    Mixing valve in a close loop

    Hi all, I am finally at the stage of my garage to hook up the in floor heat and I'm getting conflicting advice regarding water temperature. Some people report that 120F water cracked their floor and others say they run it as high as 160F. The one I have actually been in int he middle of winter...

    Anyone finished floor with Weldbond?

    I'm just interested in two things with a floor finish: preventing dusting and easy squeegeeing of water. Has anyone out there finished their floor with Weldbond and has a couple years wear on it yet?

    Mixing valve and expansion tanks with hot water heaters?

    I scored a couple year old John woods oil fired hot water heater with a Beckett burner to heat my floor, so I plan to build my closed system around that. It looks like I can keep it set low enough not to have to worry about mixing but maybe it's more effective to run it hotter and use a mixing...

    Opinions on insulation for under slab

    So I've decided to spend the extra money on Celfort C-300, but since I have a basic slab with no footer it raises a question. If I go the full 24x24 with foam, the entire slab is going to be sitting on foam and the edges are going to exposed because the gravel base is 12" above grade in the...

    Foam recomendations

    Hello everyone, I'm about to set my forms today and the guy pouring my floor suggested I use "foundation foam" that is 16psi and cut out holes where my 4 post lift will go to act as footers, the foam is what they use under residential basement floors and is half the price of C-300 pink but I'm...

    How to interface ACWU cable to conduit

    Can anyone tell me the proper way to interface ACWU or Teck 90 to conduit? I had one electrician tell me he just orders an oversize LB and buries a straight piece 2' down with the cable slipped up through it, while another said you have to get a Teck connector, but I don't see any that have an...

    DIY Ideal Air heat pumps?

    While researching mini splits I came across Ideal Air which have pre-vacuumed head units and DIY quick connects. Does anyone own one of these units? The cost of getting someone in to install a Fujitsu is really turning me off them, no one will just come in and charge it for cheap, they all...

    Whats a single pole 50A breaker for?

    I knew that my old ITE Blue Pennant panel only had a maximum breaker size of 50A available, I had always assumed it was a 2P/240v breaker. Turns out it is only a single pole, which I guess is going to be useless to me for feeding the garage, I'll have to go 2P 40A for now. Can anyone tell me...

    Heat pumps again

    The garage I'm building is going to be pretty short on space. I'll have pex in the floor for solar but it will not be hooked up for this first winter. I can get a hanging oil furnace to save space but I am considering a split heat pump since it takes up virtually no interior space. One...

    Garage door gutters/sewer grates?

    Maybe I'm not getting the terminology right here, but I've been to all the major places that sell rain gutter/weeping tile/water pipe etc. and no one even knows what I'm talking about. Since I can't have a floor drain in my slab, I want to have a grate along the front of the garage door so I...

    Attach 2-2-2-4 to breaker panel?

    Can any tell me what you need to attach 2 and 4 AWG wire to a breaker panel? the 40A breaker in the panel will not take wire that thick and I doubt it's rated for aluminum anyway. I assume there is some sort of intermediate junction box you can use?

    PEX Tubing in floor

    Hi, can anyone tell me what considerations you have to make when putting PEX into your poured slab? Do you have to go thicker than 4 1/2" to accommodate it? I want to pour a 24x24' and put PEX in for later on when I can afford to install solar panels. I will have a 4 poster lift in the garage...
