What size type anode do i need for my hot water tank.
Rv water heater anode thread size.
The thread size in these water heaters for the anode is 3 4 inch npt which is a tapered pipe thread.
Plumbonline have put together a comparison table see below to make selecting your anode as simple as possible as in most cases the owner manual for your hot water service does not detail the size.
To use a standard tap may actually remove portions of the existing threads as well as cut new threads something to be avoided in a water heater tank fitting.
Before you consider re tapping the threads re check to make sure you have the right sized anode rod.
