Dometic 310 toilet

i just installed a Dometic 310 toilet and cant seem to find the right connection for my 3/8" water line to hook to the toilet. It looks like the toilet has a 1/2" male nipple at the back. Anyone know what the hook up involves?
  • well I found out when I went back to Menards today that the 90 degree 1/2" npt x 1/2" barbed fitting that they pointed me to, was for lawn sprinkling tube, not the same as 1/2" hose. It was too big, I do have 1/2" hose to the toilet, all is good now
  • it's a 1990, and the I will check for sure here shortly, but I believe the hose going to it is 3/8" id, I guess thats uncommon?
  • 3/8" line......how old is your RV?

    If it really is 3/8" you would need to do some isle shopping in plumbing at your local hardware.

    Toilet water inlet is 1/2" NPT
