Pressure relief valve

[gareth9702]

One of my pressure relief valves has failed (Leafield A6). Has anyone succeeded in changing a valve without cutting into the tubes to gain access to the rear? All suggestions welcome.

You shouldn’t need to cut the tube. The valve is in 2 halves & unscrews. Deflate the tube, grip the back of the valve through the tube material & unscrew the front half. There is a special spanner to unscrew the front, but you may be able to improvise.

Would you guys recommend fitting PRVs retrospectively?

I am considering it. I will only be using my boat in the UK, but I am worried about the pressure/tempreture changes.

My tubes are in great shape but they are 20 years old. Ie 20 year old glue.

Many thanks.

ive had boats with and without i just blip the valve when its hot if not fitted. interestingly my new SIB has one fitted to the bow chamber only so the rest of the chambers are filled after that one meaning final pressure
