Full Version: Broken liquid force valve
Kite U.S. Forums > KiteMI & Ontario Canada Forum > Open Dialog

I noticed my kite was leaking air through the deflate valve on my 16m Liquid Force Session. The plug has a slight tear in it and appears to be causing the problem.

Unfortunately, I can not get a plug from LF and the kite has not been used very much.

Any chance someone out there has a Session that is in the graveyard? Would love to get just the plug for the deflate. It could be cut off.

For those of you who do not have a Session, it has an oversized plug.

If anyone else has a MacGuyver idea, I am certainly open to suggestions. I really don't want to replace a semi new kite.

Sorry if this is in the wrong section. Did not know where to put it.

Thanks,
Sam

Sam I once had a similar situation and found the proper size valve on one of my kids beach toys. If not bring you scissors with you to Metro next time and harvest one off Victors kite when he's not looking.

I also saw this but I'm not sure if it the correct size.

you could fabricate a new plug. get some clay stick the plug into it for a mold, pour in epoxy. I would put a short line in the mold too so you can tie the plug to your kite so you dont lose it

Common problem. Same thing happened to my Hi-Fi. I used some patching glue (rubber cement) and just glued it shut. Worked like a charm. Takes a little longer to deflate but I would just let it sit or manually deflate with my pump on reverse.

I think that might do the trick. I sent an email to Airtime to ask if it will be the correct replacement piece.

Great advice. You are so money. I am psyched to fix it myself!

11mm is standard size dump valve yours is oversize something like 20mm.

You can replace it with any size but use the oversize one here: http://www.live2kite.com/airtime-9mm-infla...alve-p-717.html. Cut out the old valve, clean with alcohol, stick new valve on. Pretty easy. Getting bladder in and out can be tricky. Use lots of baby powder. Or just glue the valve shut and be done in seconds. I know what you mean about getting geeked to repair yourself though.

That was confusing, by oversize i don't mean the valve. Any size valve will do. The patch is oversize to cover the hole you make removing the old one.

If you really want to get psyched fixing it yourself.....cut any valve off an old kite with a square of bladder at the base. Cut out old valve. Use a hot iron with wax paper and pencils to iron a seem in the bladder. Inflate to check for leaks before reinserting. Takes some practice but certainly economical. Check this site out which schools on aforementioned bladder repair technique: http://www.kitesurfingschool.org/bladderrepair.htm

warning do NOT try this dowel & iron method your first time on your bladder, it is way to easy to make a mistake and get a melted mess. you have to practice this on an old bladder first because you need to get the heat and pressure correct hot enough to seal but not so hot it melts

putting in a patch is much much easier just cut out old valve (or steam it out) and put in an airtime with an 11mm dump valve

turn the session kite into a fashionable sun tent for the wife and go buy a 2011 kite crisp and freshh

Tom great idea but I got two better options. Seal the value completely and just use the other valve to release air or use one off an old swimminng raft or rubber duckie. You can seal the valve off in a couple minutes , I know because it did to a Slingshot after that vave leaked.

Two interesting things from Airtime regarding Valve replacement.

1. Dump Valve size

"Ours will match up with your original. The 11mm designation for a deflate valve was established a long time ago but no longer reflects the actual size of the valve. Crazy, I know. But it's kind of like a 2x4. Not actually 2" x 4" any more."

Evidently what I thought was 20mm is not

2. Instructions on changing

"Typically the original valve can be removed by soaking it in hot water (not quite boiling) for about 30 seconds. If not, you will need to carefully cut away the old valve, being careful to cut as close to the valve base as possible to leave behind the smallest possible hole. Also be careful not to cut the backside of the bladder. If you need to do the cut method, place a piece of waxpaper inside the bladder to prevent the adhesive from the new valve from sticking to the backside of the bladder. This wax paper will float around inside after the install and will not cause any problems."

I pumped up the kite yesterday to assess the situation again. It does appear to be the valve.

However, the inflate valve which I thought was auto seal is not. I deflates just fine out of that vavle.

I found some epoxy in my house and sealed the deflate valve. It needs 24 hours to properly set so Iwill test it tonight after work.

Thanks for all the suggestions. I will let you know how it works out.

BTW, has anyone actually replaced a bladder or taken it out of the fabric. It looks impossible.

taking a bladder out and patching it is only slightly more difficult than taking an inner tube out of a bicycle. The only trick is always remember to tie some line on the bladder so you can pull it back in. And the first time you inflate take it slow and massage the kite while it is half inflated so you are sure it isn't twisted inside.

I tested the seal tonight. No leak!!!!

Putting the kite away took me about an extra 5 minutes to really get the air out of the struts and rolled up nicely.

I experimented with bladder repairs years ago. I had two blown out kites and I was in fairly remote location where it took weeks to get a new bladder shipped. After several surgeries and a lot of trial and error I had a frankenstein of a bladder that worked just fine. I used the method with iron/wax paper described in the earlier post. One thing I found was that making a double or "parallel" seam gave added integrity. I spent many days sidelined, patching bladder and checking for leaks. It sucked balls. It was fulfilling when I got the hang of it and actually put it to the test. At one point I was so excited to get on the water I did a hasty job inserting the bladder and it popped again when I was inflating it due to a twist. My oh my I could've just started crying like a bitch right there on the beach. In addition to the tips edt supplied: baby powder, baby powder, baby powder.

I think you made a good call gluing the valve shut. It worked for me.
