I’m replacing most of my ancient (iron) water pipes and started to remove the cold supply from the water heater. It ‘really’ didn’t want to move, so rather than use a bigger pipe wrench I stopped at the union above the heater. This got me to wondering if there is adequate support in the water heater to allow me to remove that last bit of iron pipe or if I would have more likely ‘broken’ the water heater, in trying?
And on a related note, can CPVC be used in to/out of a water heater (nat. gas), or does it have to be a certain distance away?
