My GF bought a march pump that has 3/4" FPT and MPT input and outputs. she wants to use 1/2" triclover fittings. is there an adapter that goes from the 3/4" FPT and MPT down to 1/2" for the fittings? I am no plumber and don't really understand which thread type is compatible with another, i just know I have terrible luck getting the correct ones unless i can fit it up in a store.....
