Tube valves

[zubol]

Hello everyone,

I have AVON searider 5.4 and unfortunately 4 of all tubes loose air.
I would like to ask you if its possible to replace old valves to new one without making extra hole in tubes.

Thanks for your help,

Are you sure you're losing air through the valves?

Inflate the tubes, then spray them down with soapy water - the leaks should become quite apparent (large mass of small bubbles.)

Thanks for your response.

Unfortunately I made this test a few times and I could not find any bubbles.
So I've deducted valves. When I sprayed water into the valves I saw bubbles.

I fitted complete new valves to Aging Youths Humber for him a couple of years ago, as they were buggered.

They arrived with a circular patch of Hypalon already attached, so I just cut tightly around the old valve with a craft knife and stuck the new valve/patch over the hole.
It was a bit fiddly as the tube was obviously deflated, but it wasn't too bad.

This may not be the proper way to do it, but they held air perfectly at least up until he sold it a couple of months ago.

You can also just replace the inserts if you are careful. Do a search for Ribshops post about doing it with a piece of cotton as a safety line.
I did the valves this way on my boat following his method and it worked fine, but my valves were not that bad and did only need the inserts changed.

So, there is no chance to replace them without making holes....
Iwill have extra work for winter

It would be worth trying to replace just the inserts if you can identify the type required.

They are surprisingly cheap and can make the valve like new.

Thanks all of you. There is a still huge chance to do this without "surgery"

Do you know what kind of valves my RIB has? It is AVON searider 5.4
I am a new in RIBs, this is my first boat and I do not want to brake something.

Cheers.

I have just last night changed the insides of a couple of A& valvves - first tiem I have ever done any valve type work & it was very simple stuff . A little bit of car eneeded not to drop the bits inside the tubes, but they are like new now.

As was said have alook at what you have, get the right bits & give it a go !

[zubol]

At least I have identified my valves. Its called A7.
I found repair kid for them but I have no idea how I can use it.
It is difficult ?

Regards.

I'd say get the kit to replace the bits :

and once you have this it gets pretty obvious what/ how you can change. if once you have it its not clear post again or PM me/ someone who can guide you through it.

Bascially you unscrew the body of the valve (hence the big 'nut' appearance on the face of the valve) make sure you dont drop it inside the tubees (otherwise you send ages getting them back to the whole - use the string, unclip the old spring etc & do the reverse to refit .

It is pretty easy just follow these instructions.

Better explanation from RIBShop guys & after you have done the valves ( having purchased the bits from them ) get some RIB revive as its ace stuff & will make tubes look a lot better ! Used it on mine last week ( main boat & SIB ) for an end of year clean up & its great stuff !

in most cases the valves just need a bit of care ,cleaning up and lubricating rather than total replacement ,.on most boats they are the least part of the boat to get any care and maintanence whatsoever ,
