Bonding - Arghhh

[MarkHoop]

Apologies if this is not in the correct forum but here goes.

I have an inground SWG pool that was installed in 2003. I know that the pool is not bonded. How do I know that... my in deck ladder supports have "dissolved" and there is no bonding wire coming into the pool shed which houses all of the equipment. My question is whether there is an advantage to bonding the equipment (Pump, Heater, SWG, Fridge) in the shed together or am I creating issues that may not currently exist?

Thanks in advance

You may be right that it’s not bonded but it’s also possible that it’s bonded but not run back to the equipment pad, or the wire may have been cut or buried over the past 20 years.

But all of the equipment is already bonded together through their respective ground wires. Adding an additional copper wire will do nothing to help or hurt the lack of bonding in the pool area. Are your vinyl pool walls metal? What kind of decking is around the pool? It may not be terrible to add a bonding wire, or could be lots of trouble.

Thanks for the response.

1. The equipment is inside a pool house with a concrete slab base and there is no bonding cable coming through the slab. You're right however but if the pool was bonded then I would have expected to see a copper cable in the holes in the deck where the ladder anchors used to be
2. It was my impression that there is a significant difference between being bonded and being grounded?
3. Yes, ,the walls are metal panels joined together to form the walls of the pool
4. The pool deck is stamped and colored concrete

1. I have a concrete equipment slab and the bond wire comes up through the dirt so it’s not a guaranteed one way or the other.

2. Yes, there’s a big difference. But if you aren’t bonding the pool walls or any other metal parts around the pool it isn’t bonding anyway. Connecting a wire between all the equipment wouldn’t be bonding anything, but would act as an additional ground.

You could cut out a channel all around the pool and run new wire to bond the pool wall and the ladder and then run it back to the equipment pad.

Check with your municipality.
Bonding requirements in Canada are different than in the US.

You are in Canada and have different regulations then we are familiar with in the USA.

Other methods then a bonding wire can be used to bond a pool. When a metal light fixture was used with metal conduit it can form a water bond with the pool.

Ladders not being bonded does not mean the pool and water is not bonded.
