General Discussion / Re: First Gas Cans, Now This

Nobody has found the retrofit kits at Mills Fleet? It's marketed as a "replacement spout" but comes with a new spout and barbed, push-in vent. Throw that old schnoozlepecker in the dumpster, drill a 1/2" hole in the back, pop the new vent into that hole, put the new spout on, and you now have a functional gas can again. The kits are like 9 bucks and work awesome

X3 on the vertical mount. Please make sure there is at least 4" of straight pipe on either side of the pump before any 90's to prevent turbulence and cavitation. It kills flow and pumps

M can and does get used for heating systems all the time, but as mentioned it is thinner wall. I use type L on everything including domestic water. M isn't even an option for most mechanical inspectors, if the system gets inspected. Needs to be L or K, which it thicker than L by about the same margin between M and L. ACR is the same thickness as L, but clean and registered for refrigeration usage. Much higher priced but will serve anything that L or M is suited for. As far as compressed air lines or anything high pressure or subject to wicked vibrations, lines "should" be brazed using sil-phos. Just like your central A/C lines; as the A/C unit is quite similar to an air compressor. Regular soft solder works just fine for compressed air lines if you know what you're doing

I may be a little late to the party here, but I hope you're planning on piping a plate exchanger into the boiler loop and running the radiant off a pressurized loop. I prefer individual pumps for each zone over a single loop pump and zone valves, but that's just me. 8 zone valves when 5 are on the same zone AND deadheading the pump? Come on man. Run a 1" copper loop through the plate, mixed down to 100ish degrees with 3 tees on both a supply and return header. Each zone would have it's own pump, garage and basement stats would power those 2 zone pumps and the snowmelt on a 12 hour timer or switch or whatever the customer wants to power the third pump. Each zone can run independently or all together with no risk of fighting each other. How small is this garage that it's only 1 loop??
