Old pool - no bonding system

I have a poured concrete pool built in the 60's with a permit. In attempting to add a propane heater, I have discovered that no bonding system exists. It has a poured concrete deck and approximately 8 feet wide with the pump located in a concrete block pump house. Does anyone know what the general practice was for wiring a pool prior to the 1962 code when the NEC formally began addressing swimming pool installations? How does one establish an acceptable bonding grid in this situation short of a major tear-down and re-build? Current code is fairly clear on bonding requirements and wiring requirements, however, nothing about this permitted installation meets code. I have not seen any threads that address this circumstance.
 
I am allowing this thread to remain open so long as it does not provide DIY advice. This is a serious issue and I believe we can help within the confines of the forum rules.

That said, I honestly have no good advice for the OP.
 
a 50 YO pool is probably about due to be ripped out anyway.

I can't see any practical way to do anything with it.

you would end up spending enough money that you might as well start over.

MikeB63,

Here is a discussion from another very reputable Forum on [ In-Ground ] Swimming Pool bonding.

http://www.thebuildingcodeforum.com/forum/pools-spas-hot-tubs/6530-swimming-pool-bonding.html


That said, ...IMO, depending upon where you are in the mix of actually performing some type of work on
this old swimming pool, I would strongly recommend that you have a frank discussion with the owner and
see what they actually want to do.........They may or may not want to do anything.........
"If" they want to
proceed, and you want to pursue this, ...then inform them that you will compile a list of code compliance
issues; along with the applicable code & sections [ i.e. - Swimming Pool Code, ...the NEC, ...the IRC, etc. ],
for a fee, and then evaluate the situation from there.......If you go to the effort to compile a list of
non-compliant issues, you should be paid for your efforts !

Short of removing the pool decking and starting over, I do not know of an acceptable fix for the bonding
issue.


Hope this helps !

I personally would not have any issues with continuing to use the pool as is, other than checking that the proper gfci protection is in place. IMo the cost of installing an equipotential system is not worth the very small increase in safety. Is an authority requiring you to "bring it up to code"?
 
I've encountered similar problems a couple times this summer already. The latest involved a solar array with 8 x8 aluminum support posts being installed into the concrete deck within a ft or so of a in-ground pool. When an attempt was made to tie the posts the the equi. grid, there is none.
The pool is approx 20 years old and I have no Codes to reference that era.
There does not appear to be any continuity between any metal parts, the pool light, pump, cover motor or anything.
Add to that the recent reports of pool electrocutions and shocks and it is a dilemma as to the best approach.
I am trying to find the bonding requirements for a 1990 pool :D
 
Well this pool is my pool and there is nothing bonded, including the slide, diving board, metal returns, metal ladder, metal suction/drain, concrete shell, deck, motor light posts outside the 8 ft deck, fence, or pool pump. No pool light is installed. I do not see anyway possible to bond this pool to meet code, however, there never have been any issues. If you cannot properly bond the shell, bonding anything else around the pool is pointless. In my opinion, if you bond everything accessible, it is inherently more dangerous as you create a greater chance of shock in that you connect everything in reach on one level of potential and leave the main body on a different level. The frustrating part is that the pool can never have anything added, such as a heater in this case, as the AHJ will need it to meet current code. With cost prohibitive modifications necessary to comply to current code, the pool won't be any safer with or without the new equipment. What it comes down to on the AHJ's side is liability. The AHJ (or town inspector) does not know what to tell me, or does not want to tell me what they will accept, other than it needs to be bonded to something.

In posting this thread, I was hoping to hear what others have come across in their experience and what solutions, if any, were found. Also I wanted to get opinions and a discussion of the bonding principle and the code requirements as it relates to old installations as I'm sure mine isn't the only one still out there. My training in bonding and grounding comes from my days as a power engineer in the phone company. I have no intention of ripping the pool out or performing major work in an attempt to get at every possible component as the code currently requires, but if someone came up with a reasonable approach that seemed plausible, I would consider it or propose it to the AHJ.

Thanks for your input.
