I know it doesn't help much, but Sharpie makes a nice metallic silver
ink pen. You'd still have to crawl in and find the screws the first
time. Or just stock up on plated screws and replace them as you run into
them (for which you'd still have to crawl - etc). I keep different tool
real handy for labeling dark olive drab and black containers. Layout
marks on dark materials too, for which I also keep silver lead pencils.
Sort of reverse dykem. Some of my simple but indispensable tools.

I wouldn't mind if the screws included in the units weren't black. It makes it hard to see them when you're fumbling around under a piano. Or perhaps throw in an assortment of screws, some black, some nickel plated...

Hi David,
Years ago (at least 15-20) I started finding tanks needing deep cleaning and hardware replacement. When I found out how much work it was and compared the labor cost to the price of new, it made an easy decision. I carry tanks, bars, and all hardware in my car. It's more practical for you, and better for the customer to have new. The HM5 package is wonderful for this. It gives you the complete water side and H5 humidistat with all the attachments, and hardware for both uprights and grands. And the box is small enough to easily fit in the trunk.
It sounds like you may be following one person who may have retired. This is an opportunity for you to make some money, develop good relationships with your new clients, and provide a much-needed service. Go for it!
As to the baffle, the low heat from the humidifier bar creates air movement (warm air rises) so the baffle does get that air circulating, as well as protecting the area directly above it.

I can't believe the biggest Dampp-Chaser issue for anybody is an on/off light, although it would be a good addition. It's extremely rare that I encounter a D-C system that has been kept plugged in and the water regularly filled. 7 or more times out of 10 the thing has been off for months or years and the pads are thickly crusted up with mineral deposits -- I mean 3/4" thick. I end up having to take the whole thing apart, take the tank out to the front porch or back yard and scrape all the gunk off with a pocket knife, which of course also scrapes the paint off the humidifier rod, but most times the paint has already sloughed off or been eaten off by chemical action. Then to get the last of the stuff off, I have to rub it down with a ScotchBrite pad or steel wool. The tank and filler tube are usually gross -- full of algae, mildew, mold. So I ask to go outside and borrow the garden hose to wash everything out. Can't do this when it's 20 degrees and snow on the ground, of course -- gotta reschedule for the springtime, or take the tank to your shop, clean it, and bring it back. And there's no way I know of to clean the black mildew or mold from the filler tube. Have to replace it, I guess. And in an apartment or other dwelling with no front or back yard, it's a major pain to try and do the messy job at their kitchen sink. These neglected systems are often so bad it would be better to install a whole new humidifier rod and tank, if you can get the client to pay for it.
The system does do its job -- I have one in my upright -- but I'm a technician and am aware of it all the time.
One thing I've always found a bit laughable is the baffle on the grand systems. Instead of all the warm humid air going straight up to one spot on the soundboard above the tank, the baffle just makes it go to two smaller spots at each end of the tank. I find it hard to believe that, especially in larger grands, the moisture gets distributed evenly across the whole bottom of the board. But maybe I'm wrong and the air currents in the room caused by convection, people moving around, doors opening and closing, fans, etc. are enough to create an even layer of humid air under there (??).
A problem I find with installations that are not my doing, is that the installer hasn't allowed an easy way to undo all the cords in order to be able to drop the tank all the way down to the floor. I have to undo all the clips, clamps and ties and relocate them all when I'm done. You can't do the above work with the tank still hanging from the rods! I'm in favor of just hanging all those hanked or coiled cords from hooks or from the ends of the support rods, rather than screwing everything semi-permanently to the beams, as though the unit will never have to be removed!
Again, these systems are OK; they do their job, but the majority of them get neglected and I dread what I'm going to find when I encounter one. I recommend them only for those pianos that take wild pitch swings with the changing seasons, but for the most part I can't rave about them.

I'm hoping since Charles Rempel has been on the list, it would be a good opportunity to voice my biggest irritation with dampp-chasers. It is a no-brainer in my opinion, and it shouldn't add much to the cost of the system and substantially improve it.
Those of us who install and promote humidity control know that one of the biggest problems with them is keeping them plugged in. This isn't as big an issue with the full-system as there is a light panel. However the basic system (humidistat and rods) has no LED telling you the thing is on. And so on a semi-regular basis these systems end up unplugged and the client doesn't realize it.
I hate showing up to tune a piano with an unplugged dampp-chaser!! Because if i tune it and plug it in, most likely the tuning will go south within a couple of weeks. What I usually suggest to the client is to leave it unplugged, but plug it back in 3-4 weeks before the next tuning. The other option is to just reschedule the tuning = lost income.
I've thought about trying to retrofit an led light to the system but it makes so much more sense to include it in the manufacturing process.
I hope my friends at Dampp-chaser will hear my plea! Please add a light to verify the system is on.
I also hope that other technicians will bug them about it to, as there is strength in numbers.
