Vacuum Break Valve Small (for systems up to 24 Sq/M)

A small vacuum break valve that can be easily installed into a solar pool heating system using just a small grommet to keep it secure and leak free.

Used to release the vacuum pressure of a solar system when it is turned on and off to stop the collapse of PVC pipes.

Only to be used with smaller installations less than 24m², but for most installations we would recommend a Vacrel Vacuum release valve be used.
