Another hose failure on my JJ

**Mark Chase** · September 9th, 2012, 11:47 AM

Went diving Friday and janos told me i had a leek on my ADV feed hose. Thaught it was the o ring but it was a hose failure again.

Four hoses failed so far. Both HP hoses 02 feed to the head and Diluient feed from manifold block.

Not easily noticable so well worth checking them all out.

I checked my unit after Malin but this must have hapened in the last week or so.

Nice day out and i didnt miss the dive

This was the view as we left port.

Guess there was a reason why Jan changed em to miflex hoses, you have quite an early version yeah?

I assume you are doing the same?

Not realy.

I replaced the 02 feed and SPG hoses with Miflex but the rest are just standard reg hoses cut to fit using APD conections. Mainly to avoid the cost of MTM Miflex hoses

FFS Mark, just swap them out for Miflex. I did mine en masse last year and they've been faultless since then.

I just got a load of tube from JR and replace as required using Jans reusable fittings.
Don't want washing machine hoses on my favourite bereaver

Main point of me posting was to draw attention to the problem to people with the early JJ hoses so they do a detailed inspection of their rig.

"Just" replacing all the hoses is simple enough but i baught 4 standard Miflex and three SPGs (two for the JJ one ofr a deco tank) and that set me back £300.00

I dont se a big problem butchering hoses i already own and no longer use. I have never had this sort of failure on LP hoses before.

I know mate, I'm only yanking your chain.

I originally thought that the re-usable feature was great, meaning one could easily swap out a hose in an emergency using any old hose available and I still carry a few around with me on trips where I really don't want to miss a dive.

However the fittings are a bit prone to corroding and can look a bit shit if you've had to swap them out a few times as they're soft brass.

Another benefit of using 'washing machine hoses' is that they are a lot lighter if travelling is important. And the ends stay nice and shiny

Just buy a few meters of LP hose from somewhere and rebuild the JJ hoses if you don't want to shell-out for Miflex.

I have never done a dike on the duke.

but i am willing to give it a go :D

It wasn't the Duke M8 it was the Alberny (Canadian ship full of bones in 70m I wouldn't recommend it. No so much because of the skeletons but more because i didn't think much of it as a dive)
