Would it be advisable to use a stainless or galvanized 1/4" wedge anchor to bolt down a jet pump onto concrete? Thanks in advance for your replies.

Should be fine. But that’s just my gut instinct.

Anytime I’m fastening anything of significant weight to concrete, I use ½” x ⅜” expanding concrete anchors (aka “shots”, which are expanded with a punch tool and hammer) + ⅜” threaded rod + ⅜” washers + ⅜” nuts.

I have never used a wedge anchor personally, but they work on the same principle - just different method of installation.

Also might be a good idea to put anti-vibration rubber pads between the concrete and the feet of the pump.
