gas hot water heater jump or not

What I'm saying is lots of systems are already bonded together i.e. the

mixing valve at a shower, most kitchen faucet sets, any set made of metal--

are bonded IMO don't require a jumper at the HW tank.

See 250.53(D)(1) for the requirement. :)

What is 250.53(D) talking about?
(D) Metal Underground Water Pipe. Where used as a grounding electrode, metal underground water pipe shall meet the requirements of 250.53(D)(1) and (D)(2).
Does this mean that if the pipe is NOT being used as an electrode (D)(1) and (D)(2) would not apply.
 
In Washington State we don't have to bond around a water heater if metallic mixing vavles provide continunity between hot and cold.

Benaround is correct. Jumping out the water heater went the way of the outhouse a long time ago.

Why do you say that? We still bond around them. No one using mixing valves around here.

Agreed. :)

Guess I'm in a sour mood today. A water heater is a lot more common than a filter. Whay doesn't the code just say water heater??

A water filter tends to seperate it's input and output without hope of the twain meeting again down the road. A water heater has a darn good chance of the two pipes meeting downstream.

Just because little thought is required to get the pieces of the system bonded and it takes care of itself, doesn't mean we should simply take it for granted. What I feel like is, I can breathe a small sigh of relief that installations I've done in the past were probably accidentally compliant, but it will be something I'll probably notice idly from now on.

This section would no longer apply, but 250.104(A) could be applied to the other half of the system. It just doesn't lend itself forward as well as 250.53(D) does.

Unfortunately, the way 250.53(D) is placed, it's a bonding requirement hidden amongst the grounding electrode requirements, it stinks. I've griped about this before. Common sense says it should apply regardless of whether or not the thing is used as an electrode, but I hate it when we have to apply common sense to the NEC. It should be written to remove all doubt, at least that should be their goal.

It's just a question of continuity

It's just a question of continuity

I have a Rheem 60 gallon direct jet water heater, if I remove the hot/cold water bond I lose continuity..

IMO you should always bond them.. Time required 15min, max....


FYI: (Town inspector says that some water heaters use a non conductive bottom to resist sediment damage) who knows if this is true, but my test proved to me a bond is needed..)

Mike,,

my water piping system in my home is being used for an electrode, so yes I do think it is required.
