Suction safety fittings recommendations?

HI,

I am renovating our pool. We have pool and spa, each with individual suction lines with their own valve. Generally they run together, but occasionally I shut one off, e.g. to vacuum the pool, or to drain the spa.

The spa suction goes to a SINGLE suction point on the spa drain, so is potential safety risk, even though the spa suction is almost never running whilst the main pool suction is shut off. The pool suction goes to skimmer, plus passive suction line to main drain.

Which of these types of fittings are safest for spa and main drain suction covers?:

Do you think it is safe enough if I install these covers, and have both spa and pool suctions open together in general use?

It will be extremely dificult to install a second suction point in the spa area.

I can't speak to Australian regulations, but in the US, these covers are regulated and have to pass safety inspections (usually commissioned by the CPSC directly to the company concerned).
