Healthways double hose

[Creed]

Searat,
What are the sizes of the two o-rings?

[SeaRat]

Creed,

'Sorry about not posting in a while. I have had several projects going, and have the photos that are wanted in the camera. So I should get them on the site tonight. Concerning the O-rings, I'll take some measurements tonight too. They are a different size.

On your HP Seat, try turning the seat over once you get a O-ring for it. Either side can be used.

Does anyone know where to get the nonreturn valve for the Hope page mouth piece. I tried the USDs but they don't seem to fit correctly.

Thanks,

Any suggestions on getting it out in the first place? I didn't even realize it was removable until I saw the parts diagram.

Creed,

Many times you can use a "nut pick" tool for picking walnuts out of the shell. That works, but I think four the O-rings on the seat, I had to use a very small jeweler's screwdriver. Be sure to use the flat of the blade, and simply move the screwdriver under the O-ring and ratchet it out the other end. Don't let the edge of the screwdriver get onto the seat surface though. Now, when it's out you may wish to look at it and see if this is where your leak is coming from. It may not be the seat at all, but this O-ring. My O-rings have been usable after having a good coat of silicone grease applied for several days, then wiped clean. But if it's damaged or deteriorated, it may not be enough to seal.

I was assuming that you were talking about the O-ring. If you're talking about the non-return valve in the Hope-Page mouthpiece, then a different strategy is necessary. First, if they are in fairly good shape, don't try to remove it. Simply coat it with silicone grease, and let it sit for several days. Then wipe the grease off after it has been allowed to get into the rubber.

The one way valve is missing on one side of the mouth piece. Do youknow where i can get a replacement?

Thanks,

[Creed]

Sorry, John. I was referring to the hp seat, not the o-ring.

Creed,

The HP seat is easily removable. lift the levers to expose the pin the goes through and pushes against the poppet. It can also be used to push the seat out. To do this, simply unscrew the nut that holds the adjusting screw in the lever, then with the right Allen wrench, adjust this screw in quite a ways. Then use the lever system to push down on the pin, which should loosen the seat. You can then push down with the Allen wrench on the top of the pin to push it the rest of the way through the valve body.

Excellent suggestion! It worked like a charm! Thanks!

I didn't get time to measure the O-rings, but I do have one of the photos of the insides of the Healthways Scuba:



Just one note; I have the second O-ring out-of-place in this photo. It either goes around the restrictor orifice, on above it next to the sintered filter. In my case, I tried it on the restrictor, and couldn't get it back into the valve body. So I placed it above the restrictor, between the restrictor and the sintered filter. That was the way I also found it coming out of the valve body. I have another body, and its O-ring was above it (the restrictor had no O-ring groove, so it was made both ways). More as time becomes available.

Here are some more photos of the Healthways Scuba Regulator. This is the original Healthways Scuba, but the inner parts are the same as for the second generation too, except for the exhaust system. The third generation simply added an air ejector (venturi) to the system on the main valve housing. Here are the photos (I'll do more editing after supper):



Here you can see the blue rubber band that I am using to cover the interior holes for the exhaust. This, and the exhaust diaphragm, were initially the only exhaust valves I had.


The original system had a duckbill valve in the exhaust tube. I don't have one at present (Turtleguy gave me a hint, and I will be following up on it, to get one though). So I put a mushroom valve from the Nemrod Snark III mouthpiece I have into the exhaust line. I'll test it out soon to see how this works.

Assembled, and on my twin 50s, here's what it looks like (complete with the Hope-Page mouthpiece.

John,
First, that is a great looking setup! Second, did you get a chance to measure those orings? Thanks.

[SeaRat]

Creed,

I have the seat O-ring on my desk, and it appears to be using the American Standard system, in inches. Outside diameter is 7/8 inch, inside diameter is 5/8 inch, thickness appears to be 1/16th inch. Realize that this is a very old O-ring, but it appears to be in good shape. I tried the engineering American Standard ruler (in tenths of an inch) and that did not seem to match, nor did the Metric rule.

I don't have the other O-ring, as that is in the regulator, and I'll be diving it tomorrow. So I hope to get to it this weekend.

I just dove my Healthways Scuba regulator again today, and in some pretty severe current situations. I had the mushroom valve in the exhaust line near the regulator's exhaust, and I also had both mushroom valves in the Hope-Page mouthpiece. The regulator breathed noticably harder with the intake non-return in place (this was a new, silicone mushroom from USD, not the original mushroom valve), but the mushroom valve in the exhaust line took care of the problem I had earlier (mentioned above), with water coming up into the line. That said, it would be better for the exhaust hose to not have a mushroom, and go with the original flutter valve in the regulator's exhaust horn.

Because it was breathing hard (estimate about 3" water pressure), I decided to surface and switch to my DA Aquamaster for the rest of the dive. I was evaluating a new duckbill Dan had given me for evaluation in the DA Aquamaster, and this would be a fitting last test before my write-up. You can see that on the "Buy, Sell, Trade" part of this website soon.
