    Hi Alec, my inflator hose its just too long, is it possible to shorten this hose, and if so, how?

    Hi Alec
    Me and my wife are huge fans of your tec tips and vintage videos. As new divers we ahve learned a lot from you 🙂 .
    I hade a bad freeflow as i was diving here in sweden a couple of weeks ago( water temperature was about 1 degree celsius.No big deal even if the regulator was brand new . upon closer inspection i discovered that i was able to suck air and probably water through the drysuit inflator in other words the inflator hose was leaking air backwards and i was able to get air from the second stage when the first stage was off the cylinder . May this be the cause of the free flaw ?

    Hi Alec, thanks for the time to produce all these videos. I immediately subscribed to your channel after watching a few of your videos. They are very well presented I must say.

    Regarding this video, I was watching it as my inflator hose leaks when it's connected to the power inflator. I read some resources on the internet that this is due to the worn o-ring at the quick dettach end. (Not the first stage end.) I was wondering if you have any videos that can show us how to replace this o-ring.

    Again, great videos. Keep up the good work.

    Hi, my drysuit inflator hose is leaking and also my airhorn – is this the tool I need please for at least the drysuit hose?

    And what about the o ring inside the connector?
    $5 for a schrader valve? You can get a pack of ten, complete with tool for that money?

    Thank you so much! My dive shop didn't even test my lp hose! (was too short for their bench set up)…. Nice surprise to have to orally inflate bc during dive due to leak…. Ugh. Now I can fix it myself.

  7. Karl Marx says

    Thanks a million, right in time, as I had the problem. Thanks. The tool is a "long" version (two versions available at car part stores, the short, usual version does not reach deep enough). Thanks again, super.

  8. Katja S. says

    I replaced this little part… still leaking. What about the o-ring inside? How the heck do I get it out and the new one in?

  9. KlixTrio says

    My drysuit hose was also leaking and I figured it must be similar to car and bike tires. Unfortunately I had to go diving the next day so got the lds to do it. I was pretty blown away (pun intended) when I picked up and they wanted $25.

    Cheers Alec, nice tip

  11. Tantra Dark says

    Thank you Sir. I have watched lots of your video and I found them very informative and helpful. I am planning to buy an all-around dive bag. Is the meshed one better? TIA

  12. David S says

    I got 4 Schrader valves from my boss's car! American humor. Another great tip. Alec.

    Just caught up to the newest episode. Great content! Thanks, Mr. Alec!
    Very helpful tips especially for equipment enthusiasts. BTW, what do you think of the split fins? And, just a suggestion, if you have time, is it possible to open a channel and share some great diving experiences (locations/sea lives/routes/photos/vids/logs etc) from your rich diving experiences? It will also be a refresh of a lot of precious memories I believe.

    Mr. Alec Peirce, you are truly becoming the Britanica on scuba. Thanks to you I have saved so much time and even more money. I think what you are doing is awesome and I hope you keep it up. I plan on moving to Florida and I hope to swing in and shake hands with the legend himself. Keep em coming !

  15. Igor Ajranovic says

    I have learned so much from you. Thank you so much.
    Best wishes from Serbia

  16. Bierstadt54 says

    Great tip!

  17. Tom Sinel says

    Alec, simple and effective! Very nice. People just are not aware of where in scuba that simple valve is used do they! By the way, I caught your long hair reference. I guess in retirement you decided to grow your hair like mine! lol. Keep them coming…

  18. Tom Knudsen says

    Pure excellence. Truly a tip I'd never thought about before. Frankly i am not sure if I rinse this enough, well not entierly true, I normally put my whole regulator in fresh water. But never have I used WD40 on it and pretty sure no company in Norway (as far as I know) have a valve. Need to ask my local dive store about that.. But going streight out to the shed tomorrow to look at my hoses and connectors.. PS, when the o-ring on my regulator (the one that connects to first stage DIN) tends to fall off when I screw it of the first stage, is it time to change it then (Apex xtx200) ??

  19. Михаил Олонов says

    I see your video and and i anchor in my decision to end scuba tech course. 🙂

  20. Wow. That is a new thing for me. I have now 6 to replace. I always wondered from where dies my inflators leak.

  21. Jean-Pierre Verbeke says

    Hi Alex,

    I am using a second inflation hose to inflate my smb with an inflation tube…. I am always somehow struggling to pull back the clip ring, is there a way to permanently remove that clip ring. I have another inflation hose which is then clipped on the bcd inlet.

  22. Sur Buceo says

    Anither great ttutorial Alex, THANKS!!! Just a comment, what about the o'ring sitting in the QD end of the hose. That one is difficult to change!
