Water-heater bypass valves redirect freshwater around an RV water heater during appropriate service or winterizing procedures. JR Products offers two similar three-way brass diverter valves, but the third port's pipe-thread gender differs. Compare all three fittings in the installed plumbing before buying.

Compare JR 62245 and 62255 valve connections

The third port's thread gender is the deciding difference. Confirm the plumbing layout before replacement.

MPN Component Location Connection size and style
62245 Three-way brass diverter valve Water-heater bypass line ½-inch MPT / ½-inch MPT / ½-inch FPT
62255 Three-way brass diverter valve Water-heater bypass line ½-inch MPT / ½-inch MPT / ½-inch MPT
Key fit distinction: MPT = male pipe thread and FPT = female pipe thread. 62245 has two 1/2-inch MPT connections plus one 1/2-inch FPT connection. All three 1/2-inch ports on 62255 are MPT. The valve does not establish universal compatibility with a specific RV water-heater model.

Replacement selection checklist

  1. Depressurize and drain the relevant freshwater plumbing according to the RV and water-heater manufacturer's service instructions.
  2. Identify all three existing threaded connections, including which are male and which are female.
  3. Use 62245 for the verified MPT/MPT/FPT layout and 62255 only when all three mating fittings require MPT valve ports.
  4. Match the existing valve's installed orientation and intended water-routing positions instead of inferring flow direction from exterior appearance.
  5. Use the appropriate potable-water-rated fittings and sealing method and check for leaks after restoring the water supply.
