Spa return jets where to buy?

Can anybody help John?

Assuming these are standard gunite venturi jets, remove the external fittings and the jet nozzle which is deep within the fitting. You will need a long socket wrench. Then run the jet pump and see if all of the returns are behaving the same. This will also flush out any debris that may be stuck behind a nozzle. Inspect both the nozzles and external fittings for any clogs and/or damage.
