We have lots of still usable (but not resalabe) parts from service udates, etc, I do not think we have what Dave needs, but perhaps someone else uses pumps and valves in their products and have some leftovers from service returns or R&D

Does the 4V110 solenoid value have three states ? That is can I have: pump hold vent This is an area I have very little experience as my questions probably indicate.

I know what you mean -- one of the best things about working with other folks is the opportunity to bounce ideas back and forth...

Max this is like being back in the work force. All kind of ideas. I knew I'd miss my co-workers when I retired but didn't think it would be for technical reasons. When you work for a company for 35+ years you create all kind of friendships.

The hand pump on the unit started to fail about a month ago. A call to the mfg got me a new pump since it was still under warranty. I ask if they had a non-manual pump. Not luck .. only manual pump. I suspect it's a liability to put an automatic system in a home. Could also be the cost to get it approved by OSHA.

Better the "NearlyHeadlessDave" than simply "HeadlessDave"

@"My wife's nebulizer pump is not as big but I can hear it from the other end of the house." Well, now you can get your own back :-)

I almost purchase the Harbor Freight compressor. With a coupon it was around 8 bucks. Then I started to think about noise. My wife's nebulizer pump is not as big but I can hear it from the other end of the house. Maybe a tank would be a better way to go. I have a automotive compressor I could use to fill the smaller tank. I'm not familiar with the air values. I'd need three states: pump, hold and release. My online search resulted in sticker shock ! In the hundreds of dollar range. That was from Grainger.

One issue with the inexpensive 12 volt tire pumps is that the volumetric flow is very low: It can take 10-15 minutes to fill a tire, which would alter the fill cycle time, and impact the therapy as prescribed. Although a tank is nice, a small tankless paint sprayer air pump like you'd get at Home Depot or Lowe's is a better choice. The suggestion for the 4V110 solenoid valve is a good one.

Not to worry. The tram I mentioned has two safety features. The first it the Velcro ... breaks loose around 35 psi. Second it the tram is on frame that is not fix it moves to release the pressure. I think I'll add a rip cord too so I can break the Velcro ... just in case the others fail.
