Water heaters come with two standard dielectric nipples installed from Factory to prevent that the leak was caused because whoever tightened it on to the water heater failed which caused the leak

if you have seen in the code where it says ok on electric but not on gas
please share that with me, i have looked and looked for that loop hole
it escapes me.
It is common sense, I agree with you
but all i can find is plastic pipe 18'' from water heater

Thanks for the blown up picture but I think we established that.

If it's an electric water heater I don't see any reason why not to put the piping right to the heater if there is no flue

First of all , I would run a bond / jumper wire between the 2 WH's . Than might ot might not cut down on electrolysis .

This is plastic pipe , just re-do it correctly & add any needed valves . If you wish to change it to a parallel setup , you can do it at that time .

With only 1 WH turned on , have you ever run out of WH ? If not , sounds like you are OK as is .

Really , plastic plumbing is not that difficult . Be sure to use CPVC ( hot water ) plastic , fittings , primer & appropriate glue / cement .

Or , buy the flexible fittings . Or use PEX .

Best of luck , :-)

God bless
