cold water regulator

[rubbachicken]

hi there
can anyone help me out of a desicion, i have a sherwood magnum regulator, which seems to be leaking a little too much from the dry bleed valve on the first stage, it has been regulary serviced, whilst on my last dive trip one of the dive guides was a little concerned when he saw it first underwater, any how from that perhaps it's time for me to buy a new reg, i have been recomended to buy a sherwood blizzard, {as i plan to go and dive in scappa flow in much colder water than i'm used to} i was recomended the blizzard as it will be able to cope with colder water temperature, and will be OK in warmer waters
what other regulators can you recomed for me to consider, budget and weight are the two other factors in my search for a new reg
also whats the difference between 300 bar din and 210 bar din valves, i think it's the length of the thread, can anyone confirm

thanks for reading

Dont give up on the Magnum just yet. The dry air bleed can be fixed if it is releasing to much air. Take it to a Sherwood Dealer and have them inspect it. Sometimes its as simple as adding a new rubber seat or a piston. Alot cheaper than buying a Blizzard. Good luck.

The 200 bar DIN valve is indeed shorter and has less threads. LP vs HP

hi there
thanks, do you know if the magnum will be OK in cooler water, i don't want to get up to scapper flow and find that my reg is free flowing, due to the colder water


thanks again

We dive Sherwoods year around. We have used every model they have and any freeze up's have been our fault and not the regs.

Being on an active PSD team in North Idaho we don't baby them at all and they never fail us. All of us dive the Maximus now but every model has been used in the past.

With your Magnum lower the first stage psi to that of a Blizard and it should be just fine.

Just rebuild yours, the leaking can be slowed down. A lot of people just freak out when they see a reg leaking. Just remember the Sherwoods are Trucks, not Sports Cars.

i guess as it was the guy who offered to sell me a new reg, is the same guy that would service it, so perhaps he might be wanting to make a bit more money out of me.
do you have any idea of the operating pressure of the two different regs, so that i can let the man know that i might have a little more than no knowelge of the workings of a reg {even though i don't know, it won't hurt him to think i might know what's going}
is it something that i could service myself, i'm a mechanic by trade, so a little thing like a reg can't be any more complicated than rebuilding a motor, can it

I service them to 135 to 145 psi with no problems. Sherwoods are probably one of the easiest regs to service but before attempting would try to take a class or something. Its not so much taking them apart and putting them back together that is the hard part. Its the adjusting afterwards. Adjusting the Intermediate pressure and then the 2nd stage takes practice and an understanding of how it works together. Not difficult if someone shows you and explains but not many will. Good luck and safe diving.

hi there
how much is a service kit for a sherwood magnum, the fist time i had it serviced in london they charged me $50 just for the service kit, and more than that to do the job, i make it my business to tell people to stay away from them theiving bunch of @@#*'s

This will probably make you madder.....US $8 for the 1st stage kit and US $5 for the 2nd stage kit.
