Reg servicing

Some folks get years out of a service maybe because they only dive 10 times a year.

The cost of a service kit or even just HP and LP seats isnt that much when you look at it.

I dive a lot of cave filled tanks (3600-4000psi) and I don't see the need to service my firsts. Maybe its the seat design but I have several that haven't been touched in 3+ years. Not a hint of IP creep.

2nds, well, they get it when they need it. Its pretty easy to tell when the seat is starting to go.

It has been an issue that I have brought up with Zeagle (I use Zeagle DSV and Flathead VI). There were different plastics used in HP seats and they sent me new seats to try out (POM plastic I believe). The issue they also brought up that service periods are based on consumers doing 20-30 dives per year. So when you do that amount every 3 weeks you need to service your regs more (on their recommendations).

That's funny, my zeagles haven't been rebuilt since 2003-2004. (except an envoy to O2 clean). I have a Flathead 6, DS4 and 2 envoys going strong.

Guess I shouldn't rebuild them if the new seats are a problem.........

New seats should have the better plastic so the guy said from Zeagle. It might come down to dives per service, Salt water instead of fresh, outside temp, and running the 300bar cylinders.

BTW what do you call alot of dives on High pressure tanks?

My flathead six has a several hundred dives on it as does the DS4. All were done on LP104s usually cave filled to 3600-3800. Average dive time was 60-90 minutes. A few longer and a few shorter. That said, most everything was fresh water.

I also want to add my 2nds don't last that long between rebuilds, just the firsts. Heck, I have a sherwood (1st and 2nds) that last saw a rebuild in 2002 and it still works flawlessly and breathes great (as good as it ever did)

G'day Mike,

I think the Saltwater is the major difference we have. Corrosion Build up is very noticable and ultrasonic cleaning is a must for a proper job. This is after a wash at the end of the day.

The DSV i have gets a flogging as its my single tank reg (Flathead VI are on my doubles). The DSV has well over 1000 dives on it and maybe I have had a full service kit put in twice. I pull it apart every 6 months or when the diving is quiet and inspect and clean.

What is your IP setting? 135psi as recommended or a little higher?

Your probably right on the saltwater stuff for the non-evironmental regs but the DS4 and Flathead 6 are environmentally sealed. Salt shouldn't affect perfromance.

On the IP, I actually go a bit lower. 130ish range. Its easier on the 2nd's seat and drops the tendency to free flow with worn 2nd stage seats. Still plenty good to 200'.

I do carry the tools with me on a dive trip and upping the IP is incredibly easy to do if I would want to. Heck, I carry enough to rebuild a reg in a hotel, which I have done before......

G'day Mike,

That maybe another issue as I am used to Apeks gear and set my IP around the 140-145psi mark. I might try lowering the IP to the 130-135psi range and see what happens. Might lengthen the life of my HP and LP seats.

Cheers Aussie
