I am in the middle of a new construction. We want to eventually add a pool with a pool heater. Can we use the same gas line that would be used for outdoor kitchen or should I get a separate gas line stubbed out?
A pool heater's gas supply line is typically the 1st thing off a meter, even before the house supply because of the size of the gas demand.
As to where the connection for the outdoor kitchen is made, that is best left to the gas plumber. Every home is different and without seeing the plans, we would have no way of knowing without seeing your situation.
