I had several units for some years in studios at CSU Long Beach. At some point, a PLSS employee told me to use distilled water with a little pinch of salt. Plenty of the electrolytes to make the system work, and I used distilled water plus the juice, and I thought I had a lot less crust on my pads when it was time to change them.

At least where I live, tap water has lots of minerals, so it will lead to the pads having a short life. Better to start with tap water (for its electrolytes), then use distilled water thereafter. The electrolytes won't go anywhere. Or use distilled with the treatment liquid.
If you start with just pure distilled, the water level light will blink constantly, as will the pad light. (The unit will function fine, as long as you don't worry about the lights, and reach under the piano to feel for water level).

Good point, Garret. I followed up with Ed about this one, and he said that he only uses distilled water for the initial installation. After that, normal tap water and the PLSS juice.

regardless of what type of water you use it's very important to use the pad treatment. Using distilled water without the pad treatment can cause the system to not function correctly. Distilled water will not conduct electricity appropriately

My friend and colleague Ed Whitting sent the following, useful response to me personally. Hehas given me permission to share it with the group.
Dear Alan, watch your texts, I will be sending pictures of my tools and, I don't own a stubby Phillips.
If the support beams are painted black I use screws as supplied. If they are beautifully clear finished spruce I use wire ties to hold everything in place. The most critical point is the orientation of the humidifier tanks to one another because of the connecting tube.
It is much easier to place tanks on the hanger rods if they are cut to the right length. I use bolt cutters.
Note: put the plastic rod hangers on the rod, in the right direction before cutting the rod; the bolt cutters deform the rod at the cut point enough to make putting them on later very difficult.
I Use a 1/4" nut driver that has been magnetized for putting in the screws. Some use a portable drill, I don't. I also have a magnetized socket and ratchet that gets into tight places.
Dry fit everything. I put in the dehumidifiers first, then plan the tanks and humidistat. Plug in the 3 point electrical connector and plug in something on both sides of the humidistat so you know how much room you need for the connected humidistat.
Use the Velcro to hold it in place while you determine if there is enough room to unplug everything: Trial and error.
If using wire ties, mount the dehumidifiers in their plastic keepers. Go around the dehumidifer and beam make it med., tight , cut off the waste rend but leave enough do you can pull it tighter on your next visit. It takes longer to install this way.
Install the complete system but don't cut the tank connecting hose until everything else is in place. I put the low water sensor in the 2nd tank; it just seems mechanically correct.
Bring 2 gallons of distilled water
Watch for tool pictures
Hope this helps.

Hi Alan,
You probably have something like this already, but just in case...
I bought a 12volt DeWalt drill/driver which is small enough to fit into these tight spaces. Works wonders on a Steinway B.
I also bought a DeWalt 90° adapter which has paid for itself many times over. Add in a few 1/4" bits and you are all set.
Like I said, you may have a setup like this already, but someone reading this may benefit.
Good luck, for a big of a beast as they are there is not a lot of elbow room under there.

Greetings,
I will soon be installing a two-tank Piano Life-Saver System in a Bosendorfer 225 (ca. 2010). Although I have not seen the beam configuration under the soundboard in this particular Bosendorfer, I expect that the beams are in a "grid" configuration (as opposed to the more common "fan" configuration), like the two other Bosendorfers in which I have installed PLS systems. The "grid" makes fitting in the various components--at the recommended distances from each other--more of a challenge than usual.
If anyone has any experience-born advice on how best to lay out the components, and other tips for working in these relatively tight spaces (I am already armed with a stubby Philips-head screwdriver!), I would very much appreciate hearing about that.
Thanks,
Alan
