Using standard primer and glue thx.

I just extended my emergency overflow piping to the sump and used
Carlon all weather quick set clear PVC glue, that requires no primer, and had no problems. It's the primer not the glue that I would concerned with. This glue is made for the grey electrical PVC which is the same as the white stuff except the grey pipe and fittings are uv resistant I'm told. Bought it at Home depot.
