I don't have a water level plug but obviously have a whistle. What sort of PSI pressure is recommended?

From memory, mamod SV lifts off at 15 psi.

A 1/4 bsf brass bolt with the head cut off, a 3mm hole through the centre, makes a cheap and simple adaptor for the whistle hole.

If it helps, send me a PM and I will make one and pop it in the post.
