RSR 750 XXL Sump-Pump Connector

[ReefKeeperElite]

Have any 750 owners who have hard-plumbed the return and drains know if the part below can also be used with the 750? Can't find one that specifically indicates RSR 750. Looking to use these on all 3 fittings, remove the barb, and screen in a 3/4 MPT nipple to 1" slip, as outlined by Broadfield here on R2R. TIA.

#42221 is what you want. You can screw a 3/4” pipe into it after removing the nipple. And it doesn’t matter what it’s labeled as. It’s getting used for a purpose it was not meant to be used for.

Also, you can sand the exterior smooth to fit a 1” pipe coupler onto it and glue it.
