I have to raise a ten foot 2-1/2 IMC riser about three feet. Building is going from a flat roof to a trussed one. Can I use a 3 foot piece of PVC between the meter base and the 10 foot IMC?
I sugest that you use a threadless IMC coupling and connector and a short length of IMC to raise your riser mast. This will avoid having a problem with bonding the metal section of the mast. -- Tom H
