plumbing question

[max6220]

getting ready to install all my waste plumbing, My question is the pipe going into the grey tank do you just cut a hole with a hole saw then caulk it in, use a grommet type fitting, glue a fitting to the tank ?? thanks

The grommet type fittings like Uniseal are great. IMO, better than trying to caulk as they do allow for some wiggle as you bounce down the road and are removable if that is ever necessary

max6220, Howdy;

Fully agree with MtnDon on the grommet seals. It's what is used for the full-sized RVs.
