I should note that my Deluxe was hotrodded with a snorkel, which is why I was able to compare it to the Goldie!

Okay, been doin' a lot of thinkin'; yeah that was that horrible noise you might have heard! I may have figured out an exhaust valve for this thing: I had to clear my hoses way too many times, so I for one am going to install one. What I have in mind will be bolted in using the bolts/screws that hold the top can/cover on. Phil; as a side note, would you please post an image of the clamp for holding on the diaphragm? Jaybird Jaybird, Does this mean that you have used your DivAir in the water? If so, describe the experience, if you would, please. By the way, some of the ol' timers may have put a mushroom exhaust disc/valve from a Hope-Page into the convolutions near the exhaust horn on the exhaust hose. 😀 John This is what I was thinking!

Phil and Jaybird,
I just checked, and the H-P wagonwheel will not fit these hoses. What will is the second generation non-return from the Healthways SCUBA Deluxe and Healthways Gold Label regulators. So don't try putting the H-P wagonwheel into these hoses, as you'll probably rip them. Also, this works best in non-spiral hoses (USD/Voit style hoses).

I see there's a bit of corrosion and a bit of paint to clean up still, but ain't she sweet? Phil

If I can find some stainless wire/rod that's long enough, I'd like to try and make my clamp with that. The clamp I made was out of galvanized sheet metal/steel. John, I already tried the second generation HW-wagon wheels, 'long time ago Grumble, grumble, grumble... Don't worry gang, I will most certainly share the specs when I make this valve, and it's nothing fancy what I have in mind Side note: Oh boy, I just found an old Sear lantern from 1967 today, not J.C. Higgins or Ted Williams but a blue Sears Jaybird

You know, this thing had a lifetime warranty! It's still alive! Who do I send it to?
Or was it the company's lifetime... Shoot.

I remember about 10 years ago I got a letter in the mail saying that such-and-such company would extend the warranty on my car: both my wife and I just about burst a lung laughing; my two cars were a 1959 Rambler American and a 1956 Buick Century. Just for grins you grins you should find out the last address of the L.G. Arpin Co. and send it there explaining your problems: it would be funny if any one at all answered, even a response of, "We have no idea of what the heck yer talkin' 'bout pal..." JB

SwimJim's Divair Goes Deep- Last weekend at Fortune Pond, SwimJim put his restored Divair double hose regulator thru its paces. He strapped on a bail out bottle and took no chances, but the Divair worked perfectly. - Note the reserve lever. Very hard to reach but it DOES work.

Phil, here's my current theory behind my exhaust valve: I'm using a compass to empirically measure the arc of the channel in the regulator body. With a pen in the compass, I'm recreating/drawing those arcs on an old inner tube. The critical part is where it rests in that channel and over the exhaust port. I'm making it long enough to reach back to the two screws/bolts. Next, I'm going to cut two pieces of metal, same arc size: these will be metal tabs to help hold the valve down but stop just before the exhaust port. I'll glue/RTV both rubber valve and metal tabs down, as well as use a nut on the screws/bolts. If done right, at least in theory, the air bubble in the air horn should keep the water out, for the most part: hopefully the air bubble and water pressure will find equilibrium? So before someone jumps down my neck and tells me how bad this design is, please remember, this is a work in progress, and as far as I know, no one has any sort of exhaust valve on theirs, and if they do, it hasn't been made known Jaybird EDIT: Here's a dummy valve I made so you can better understand my idea:

Here's a useless bit of trivia: the metal can on a Divair and a DVD both have the same outside diameter!

More ideas: if I add two cross bars, or grates, like on wagon-wheels, it would give the valve somewhere to seat/rest better. If I remove part of the flange that holds the cover in place, that would give me a better seating for the valve too... I'll get this thing figured out yet!

I don't mean to try to one up you here. Your idea might be the best ever. I am interested, and want to see more.
BUT, I've been thinking about this, in re: this reg and the original SCUBA. I'm thinking that simpler is better.
What about a short section of hose 1-2" off the reg, with a simple wagon wheel/mushroom valve inserted into that short section, and coupled to the long exhaust hose to the mp? This would allow a larger diameter valve than the port could accommodate. You could get the wagon wheel right up to the fiberglass exhaust port, pretty much. Tsps rather than cupfuls. This is what John has been talking about, only he says the one way will be inserted into the hose. Not sure about that, but he could probably explain in finer detail.

Hmmmm? If I'm reading you right, you'd still be pushing that water and air through a confined space, that being the air horn, no? Please, keep the ideas coming! JB EDIT: If the air horns on these weren't so choked down, thicker, an original Scuba duckbill would be perfect...

- SwimJim was explaining how his Divair performed during his dive down to 130 feet. He said something about the Divair not having a duckbill (or exhaust valve... I forget exactly how he said it). But he said that it didn't seem to need one and his hoses were all totally dry for his entire 30 minute dive. He said he didn't even have to do the usual hose clearing roll that other double hose regs can sometimes need to clear the water out. - I don't know the workings of a Divair but I see you are discussing exhaust valves and modifications. I'm thinking that SwimJim's dive shows that maybe what is perceived as a problem at the surface may not be a problem at all in the actual DIVING use of the Divair?
