Aerotec air leak through valves

[piotr]

I've noticed my Aerotec is loosing air through the valves. Did some googling and it looks like I need to clean or replace the "inner recessed valve"

This: http://www.westportmarina.com/zodiac/ZValvetucksm.jpg

Is there a special tool needed to replace this valve ?

ps: when I screw the cap on, the valve is at some point loosing air because the cap pushes the inner valve down, is this normal ?

All these types of valves hiss slightly or lose air, check the manual etc. The valve is *not* the final seal, the final cap with rubber O ring *is* the seal. If it is leaking there then just replace the O ring. Inner valves are a few quid on eBay and simple screw in/out with needle nose pliers.

Thanks for the info !

The cap o-rings turn square and shrink with age. I like to smear a TINY amount of Dow Corning 111 silicone grease on them.

I assume you have the semi-recessed valves. Are your caps threaded, or do you have the quarter-turn caps with the little L-shaped legs?

It is normal for the Z60055 insert to hiss a little bit.

That is the insert...it is the same for both the threaded & the quarter-turn semi-recessed valves.

What does the cap look like?
