newbie question about inflating

Hi all,

I have been lurking on this forum for a while. It was really helping me greatly to browse through the forums and get the little bits of gems.

Our family have bought a second hand inflatable boat. It is super tough and the guy have really taken care of the motor (sparkling inside). The inflatable is in good condition and is quite heavy so I am guessing the quality is not too bad.

We haven't had the chance to try it yet as it has been raining lately in Sydney.

I just tried to inflate the boat this morning and every time I take the pump adaptor out of the valve the air just escape.

When I try to lock the valve pushpin then the pump doesn't blow any air in I have tried to leave it in for a few minutes and no air in.

As soon as I release the valve and put the adapter back only then will it pump (then of course when I remove the adapter a lot of air gushes out before I can get my hand to lock the valve pushpin)

I had a look on google and saw that there was one type of adapter that had a pin in it to push the pushpin in the valve. is it the one I need (or maybe I can just drill the hole in) to get or did I get it totally wrong?

I have one that looks like this:
The one is saw online looked like this:


I am using an electric inflator (not the expensive ones)

Sorry for the beginner question, and thank you very much for your help !

I bought a whole lot of accessories and I will show off the boat next time

hi and welcome the type of valve you have with that type of adapter is called a halkey Roberts . generally with this type when the pin in the centre is pushed in and turned a quarter turn it is locked in the open (deflate) position .to inflate it should be then turned back a quarter turn until it springs out then its ready to inflate the small bar in the adaptor is meant to push the pin against spring pressure open when inflating when you unplug the adaptor a combination of air pressure and the spring should close the valve no other turning is required apart from installing the outer lid/stopper whatever its called.

Thanks that makes sense, however I am unable to find any online or they don't specify if it has one of those pin. Do all halkey roberts have the pin? Mine certainly doesn't

The little yellow part in the centre. Push in and twist clockwise to lock open, opposite to close. Leave it in the closed position when inflating (it should be on a spring).

I think I have a problem when the adapter not the valve, the valve open and close but when it is closed it doesn't pump, I am thinking it has to be because my adapter doesn't have a pin or it should work without pin?

Some adapters have an extra little plastic lug on the end to open the valve. These may have snapped off on yours. They were on a Chinese 'Blue Wind' sib that I owned.

Thanks, that makes sense. On the photos I rarely if ever see the pin so I wasn't sure that it was something that was standard now I will try to drill a hole and add a paperclip to see if it works . I will still order a new one but we're going out this week if the weather is good

Of course I will post if it worked tomorrow !

By plastic lug do you mean the transparent ring around the adapter or is it inside? If it's the former I do have a small plastic bit around the adapter but it doesn't do much.

It's the two lugs below the bayonet fitting that protrude down into the valve body. Look at my last picture and you'll see a difference from the standard fitting.
