Anyone found any practical difference in polyethlyene (not rubber) foam pipe insulation that is available at the supply house versus the big box? I know for fact that Armacell (at least as of a year ago) manufactures Home Depot's Everbilt pipe insulation, though it is run on a different...

@Sylvan, @bigb56 and @Fitter30 - thanks so much for the speedy suggestion and info. You all are always so helpful! The 'more force' worked, so now I can install the thermostatic valve. I just wanted to make sure there wasn't some chemical bond between stainless and brass or that the stainless...

I have a stainless uponor heating manifold 1" valve with a uponor pex adapter installed, which I need to remove. At first go, with two 12" adjustable wrenches, it didn't give; however, I also didn't max out torque for fear of damage. Those threads have both megalock and blue monster teflon tape...

I'm starting to loose confidence in Uponor. They don't manage their vendors well (trying to sell HePEX that has had it's barrier all scratched up or had ends driven over), they don't ensure consistent pricing (a local supply house that I don't frequent and don't have an account with charged me...

I'm reassembling some heating, before temps plunge, and am working with 1" Uponor HePEX a and an older 2432-20 M12 expansion tool with factory head. I've done a few hundred connections previously, but been a couple years since I did much 1". 1) The head only rotates about 1/3 of a rotation (two...

Here in the west, water resources are scarce - it's the real deal as is conservation, else we'll be screwed when drought hits. So, I fully support that. However, do need a sink that can fill a bucket quickly. From what I can tell, Laundry Trays and Service Sinks are excluded from watersense...

Can anyone recommend a good utility / laundry sink faucet that is: - Deck mounted - single or triple hole - Good build quality and reputable company like Moen or Delta for easy to service and parts availability. - Can be turned on with messy hands (below style or the wing style handles) - Has...

I have some 30ish year old seasonal hose bibs that are pressurized off a valve on the irrigation manifold, and massive (4") roots have lead to an underground leak on the blue line and pinching another zone (below). For the repair of the seasonal hose bib poly (blue), is it necessary to use...

Ok, thanks. I thought I had successfully avoided buying a tool that would be used once (crimpers... instead, bought factory crimped sections), but I'll either do that or the metal strip spacer. Either way, I think I have to make a 6" section first, where I can remove it from above, but would...

@Fitter30 - went to install the ductwork, and ran into a real hitch. The flange on the bottom of the roof-top blower does not mate up correctly with 10" ducting. It's more like 10-1/4"-ish, but maybe not quite round. I called and talked to Broan tech support, who originally said it should be...

Can you clarify what you're saying? I have a number of low-lead brass valves in my plumbing and faucets with low lead brass valves. While of course some much lower level of lead will leach, you're saying... ? I believe thoughtfully grown produce also has low levels of lead, arsenic, chromium...

Residential frost-free wall mounted hose bibs - do inspectors in your area require them to be lead free? I was getting ready to order a hot+cold frost free hose bib, and realized that Woodford, one of the most respected manufacturers of frost free hose bibs, only makes one low-lead ('lead...

Fitter30... For galvanized ducting - what screw size is preferred? #8x1/2"? By self-tapping, you're referring to the first one, not the second (self-drilling) one? Edit: I removed a question about duct sealants, as I spoke to specialist at Hercules, and he guided me to their in-house...

Thanks. Most of the supply houses here I only see 26 and 30, vs 28. I'm not quite sure what I have already, but it feels a bit flimsy. Have grinders that should work and use PPE. I think I actually have both mastic and aluminum tape with a squeegee. Is one better for this application? I've...

Scratch this post... the duct work I bought from the supply house some time back isn't the 26 gauge I had on the receipt. I put a mic on it, instead of calipers, and read 0.014" +/- 0.001". I don't know what that is... maybe thick 30 gauge. I'll get new duct that's actually 26 gauge.

Fair enough. It's just trying to set a range based on current draw. Really old re-construction. Most of the home will be reasonably tight. Lunos spot HRVs will be used. There's no ducting on those; they work in pairs push-pull. Hopefully I'll be able to adjust the makeup air controls to be...

The roof top exhaust blower will be powered through the range hood, which as a pot style infinitely variable control. The makeup air system uses the Fantech FMAC controller that a 3rd party developed for their gen 1 makeup air systems, also used in their Gen 2. It uses CTs to measure current...

Thanks - I'll check it out. Sounds like this is not a rod but a cable.

I found a mepacademy.com article referencing a SMACNA chart, shown below. Also a NC mechanical code requirement of strapping at least 1" and an equal or thicker gauge to the duct. Now, that silencer is 30 lbs (much heavier than ductwork and 14" OD), so I assume I should go with the 1", 22 gauge...

Thanks! I went back and forth on it for grease reasons, but do see range hood mfg's selling them and the inspector approved. Residential range exhaust systems are offensively noisy! I might have heightened concern because I have a mitsubishi mini spit compressor on a solid brick wall that...
