Has hot weather burst my RIB?

Hi,
During the recent autumnul cooling of the weather I pumped up my tubes a bit as they were looking flabby on my Novamarine RH450. Then we got the recent warmer spell, and you guessed it the expansion has ruptured one of my tubes somewhere. It's not a fast leak, probably takes half an hour before it goes down noticably, so the boat is still usable, just incredibly anoying as The boat has zero repairs and I have not had to put air in it all summer.

Is there an expansion valve somewhere that could be letting the air out. I can't find the leak, where do they normally go when they are overinflated? I hope it''s not gone in the end of the tube thats not accessible where it butts to the other one! the inflation valve for the offending section is not leaking, nor can I find any other leak on the visible bits of the tube.

This must happen a lot to people. Do any ribs have pressure relief valves to prevent such damage?

They usually only fit pressure relief valves in warmer climates. Pump it up and go over it with some soapy water should be an easy locate and repair, if in doubt give kieron a ring at the ribshop, local to hamble.

I'd be amazed if it was caused by the 'hot' weather. I've dark blue tubes on both boats & while they get hot they never get so hot as to make me worry about the glue etc .........

There are some threads on here about this if you want to have a read.

Still , as suggested - get a bucket soapy water out & off you go - if you want it to look really good as a repair get a prop like RIBSHOP to do it .

First place to check/test with the soapy water, is the valves themselves.

Best to get a couple of heavily laden bikini clad lovelies to do it, hands-free. Far more effective.

I'd even bring a few patio heaters round to keep the temp up!

I pumped up my tubes recently as they were definitely looking a bit saggy - but the sun made them as hard as concrete.... I had assumed the valves would take care of regulating any over inflation. It seems from reading here that this is not the case...
