Automatic Relief Valves

[WayDownUnder]

Has anyone advice on replacing Halkey-Roberts valves with auto relief valves? I'd like to be able to leave my boat lakeside (in the sun) without the need to deflate it to absolute safe lower pressure.

Add in Leafield A6 pressure relief valves into some of your tube compartments. Doesn't need to be every tube but how you inflate becomes important, so the other compartments air pressure can push against the tube compartment with the relief valve. Installation requires cutting a large enough hole to insert the inside nut part, glue on a patch/circle, then install the relief valve. Not really that hard, but there are a few tricks.

I did add two relief valves to my boat, which has five compartments, and it is nice no longer worrying about it over pressurizing.

Thank you Peter. I had hoped that there would be relief valve that I could screw into the existing bases.
I'm not sure I'm ready to cut holes just yet. But, thank you again for your advice.

on my humber the relief valves are separate to the inflation valves. its sometimes a little concerning though when your out fishing on a hot day and one starts hissing

My mistake, I hadn't realised that you cannot inflate using the relief valves.
