Hoping someone can help me troubleshoot this.

I have this iSUP..www.kitedanmark.dk/naked-race-addict-oppustelig-sup.html
Bought second hand, good condition. Have been paddling for about 6 months now in Copenhagen, Denmark, having fun!

However when I inflate it from 5PSI up to 15PSI the needle starts going fown, while I am inflating it. This is visible when I stop pumping...the needle starts creeping downwards. I cant hear any sound. Is the board really deflating???

This creates a panic where I have to really pump intensively and fight against the deflate to get up to the 15PSI.
Once I have removed the pump hose, and screwed the cover over the valve, all is fine. During paddling it doesnt seem to leak.

I researched a bit and then thought that the little plastic bridge inside the hose might be pressing on the valve a bit, causing it to deflate, so I cut that out with a penknife, so now it fully relies on the pressure to push the valve down and let air in.

What should I check for next...should I research getting a new valve installed? Or could it be the pump, the needle or pump hose? Suggestions welcome.

I have three inflatibles now from the same brand, so i have three identical pumps. I was pumping up my new fishing isup, with my oldest pump and i noticed this was happening to me. I had pumped it up to 5 psi and then reconnected and this sensation was happening to me. I think it was the pump, or hose, def. not the board if that helps. Just happened yesterday so ill keep you posted.

It'll be a valve in your pump. Dismantle it and have a look at the head.

Hose problem, tried other pump today and no worries, cgeck for air leakage at hose connector to pump and gauge at pump.
