What is the best way to install? take apart or leave as one unit???? The always leaks , like this one not to....

Hi, The easiest way to install is separate it leaving the locking nut in place, then connect the locking nut to the other side.

Does the o-ring come with the pump side union half (glued in the groove or separate) ? I tried to remove the old o-ring, it was leaking, and it appears that it was glued into the o-ring groove. I could not remove the leaking o-ring without scratching the groove and leaving pieces of the o-ring in the union groove.

Hello, Jerry. The O-Ring/Gasket  (SPX1425Z6) and (SPX1485C) should not be glued in. It may corroded by chlorine or years of use.

Does this union include a flow control switching fro d.e. filter to Cartridge but noticed my D.e. filter has a flow control washer. thanks

Hi, Roger. This union does not have such a feature. That part is specific to the D.E. Filter you have.
