defective goods are a legitimate reason for a charge back, if the seller won't correct the issue.

the electric caulk guns I've seen have all been designed around high-volume dispensing of thick sealants, as used for windshields, masonry, and construction adhesives. Dispensing these by hand is a pain, because you either have to squeeze lots or squeeze hard, or both. I know windshield...

That depends on the battery. There are a lot of LiFepo batteries designed for drop in replacement of lead acid batteries. They have built in BMS to convert lead acid charging voltage to a whatever it is that they need. Such batteries are available for a lot of applications, from deep cycle use...

cool story, but like most things, an anecdote is pretty worthless as evidence. There is outstandingly strong statistical data that shows asbestos exposure increases the risk of lung cancer, that the risk is dose dependent, and there is a well understood mechanism of action. It’s also...

Too fast flow increases noise (probably not a problem in pex in concrete), and can cause erosion of the pipe. Even in laminar flow, higher flow rates transfer more heat, becuase the boundry layer is thinner.

I had one of those. When it clogged, I replaced it with a random one from amazon that was 1/5 the price. As far as I could tell, it was identical. It lasted until I dropped it from a ladder. it got replaced with another generic one, which lasted long enough, but I left a can on it for a...

Don't forget they can be painted. I've also seen a lineset that were hidden inside an actual downspout, run up to, but not connected to the gutters. I only noticed because I thought it weird there were two downspouts so close to each other, and looked long enough to see where the lineset left...

Call WD, and tell them their dealer *****. Good manufacturers consider that when deciding whether to renew a contract, it's bad for them if people won't buy their equipment because they have to deal with a local *******. It's also possible they can light a fire under the dealer's *** so it...

The problem with asphalt shingles, at least for insurance companies, is that susceptibility to wind and hail damage goes up dramatically with age, and there's not a good way to test for that. The shingles can look perfectly fine, and be leak free, but then suffer unnoticed (or noticed but not...

This kind of stuff shows up at the local habitat restore from time to time. A couple years ago, they had a bunch from an extended stay hotel.

Their insurance company can also pay your contractor to do it. That’s what anyone else would do.

For which he provided a worked example, showing the loss is four times higher with 3/8 tube instead of 1/2. Installing a pump capable of providing enough head is not the issue, it’s that it takes more power to do so. If it’s 20 extra watts for 3/8, then you have about (24hr/day * 180 days/yr *...

that's great. How is that supposed to work when the guy drilling the hole doesn't know there's a truss there, because the floor already has sheathing on it? Or in a remodel? or the drawing tells them to put their stuff their? Serious question.

It happens when the wall is directly on top of, and parallel with, the truss. There's no way to get into the stud bay without drilling a hole in the top (or bottom) chord.

One big advantage of floor trusses is that they have lots of empty space. that makes it possible for even a plumber or an HVAC installer to do their thing without cutting members.

No. It doesn't. Some places near St Louis might, but I think that's all in Missouri. Chicago has its own rules, but with the exception of requiring conduit it's pretty close to the NEC these days. There are some differences about conduit fill, sizing of grounding conductors, and much less...

<duplicate, sorry>

Almost nothing if you value your time at nothing. Pawn shops here know the value of what they're selling, you will not find a bargain there. Garage and estate sales have stuff, typically for the first five minutes, then a reseller or hoarder comes in and buys the lot, and lots of estate sale...

the only youtube tool opinions I take at all seriously are ones from people who don't review tools, they just use them. The reviewers are all shills, they know who is buttering their bread, and it ain't the viewer.

I've bought some stuff from the randomly named brands on amazon. Sockets and wrenches have all been fine for what I've used them for, which is basically been 'I need to put a few tools somewhere, for basic tool stuff'. Screwdrivers have been ****, which I expected, but I do use some o the...
