Water in the tube

I was launching the boat yesterday and damaged one of the side tubes, vertical rip about 10 cm long. This happened in the water and while I was getting the boat back to the shore, some water had gotten inside the tube. I was able to get very most of it out, however I think some is still there, even If I get all water out, some moisture will definitely stay inside.

Is there a trick to get the tube back dry inside again?

How can I unscre the HALKEY ROBERTS valve without special tool?

p.s. I've picks in the camera and will post it a little later, kind of tired from the trip now.

i once lent out
an avon redcrest dinghy ,when it came back , it had a fair amount of water in a tube ,,the borrowers son had used the foot pump to top up the tubes when it was left tied up and rain water had filled the boat ,hence a few pints of water was blown into the tube via the foot bellows /pump ,,. i finished up removing a repaired patch to get the water out as it was easier than trying to remove the very old seized metal valves ,,i dont think that it will cause much problems with a hypalon boat ,,eg fabric sticking together if left deflated for long periods as a you must get a certain amount of ambiant moisture in the air when filling,in different climates anyhow , i suppose you could push some of those silica gel sachets in side for a few hours ,the type you get when you buy things in boxes to absorb moisture or even old newspaper as long as you can get it out .mart

Thanks for the tip, I'll try.

Here is the pic of the ripped side.

Q 1: how to get the water fully drained out of the tube?
Q 2: How can I unscrew the HALKEY ROBERTS valve without special tool?

I started patching up the hole. I just let as much water as possible via this rip, and the rest of the moisture hopefully will leave via unlocked valve.

I made several pics that I'll post later. I will do pressure test tomorrow??? May be on Tuesday, I'll let the adhesive get dry more time.

NVM about my Q2, as I've used thin pliers to unscrew the HL valve.

Re: the water inside the tubes. Just leave the tubes out in the sun for a day - the moisture will evaporate and vent.

The hole you have there will require an inner repair as well as the outer.

I've made a simple guide for repairing holes bigger than 1".

Link is here - FYI.

Thanks, This is a nice basic guide.

However, rather than doing the inside patch, I did a little different. I stitched the torn fabric and applied patch with about 3cm overlap over the stitch. I'll let glue dry and will have a pressure test it in 2 days.

We'll see what happens.

Get a hand pump for inflating the tubes that will also deflate… stick it into the valve and start deflating with the valve at the lowest point and you should manage to suck out 99% of the water. Have done this and it did work.

1. due to the size of the rip, I've decided to stitch it before applying the patch.

2. patch has just been applied. I always use Stabond 2 part PVC adhesive. Works great. Takes 24hrs to fully dry.

3. about 36hrs later the tube, along with the rest of the boat has been inflated. Seems to be airtight. Not sure what to do with the different color of the patch, as it is a little too gray.

If you have any questions, just ask me.
