Just been pumping up the tubes on my Zodiac Futura with a foot pump and the pressure gauge. However it doesnt ever seem to set in the "Max" zone. When i pump it goes way above the green, then very slowly drops until its where i was 10 minutes ago (a margin below the green max zone!)
Do i need to just give this a few more hours or will it soon go pop! :-)
Are you using a pressure gauge incorporated on the pump body that has a central pushing pin on the connecting air valve hose? If so, maybe is loosing air pressure through the hose or pump body specially if the air valve is kept open by the air valve adapter, the air tends to go back to the inflator and be lost somewhere. Had some problems with this kind of inflators, no longer are used, that's why double action pumps & hand pressure gauges are employed for better/exact air fillings/readings.
Check the inflator by closing the air valve exit with finger, push with your foot to see if retains air while pushing, if not, it's leaking somewhere. If this is not the problem, check air valves & tubes by spraying soapy water to detect any air leaks on these main/critical parts.
